Show HN: I'm an airline pilot – I built interactive graphs/globes of my flights

1539 points by jamesharding 1y ago

Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all https://jameshard.ing/pilot/globes/all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

alabhyajindal 1y ago
Very cool! I didn't know pilots are required to maintain a logbook. What's the official recommendation for this - using a paper logbook?
- jamesharding 1y ago
  Each country has slightly different requirements! For the US, here is the FAA rule for it: https://www.ecfr.gov/current/title-14/chapter-I/subchapter-D/part-61/subpart-A/section-61.51 https://www.ecfr.gov/current/title-14/chapter-I/subchapter-D... A lot of people still use paper (and fill it in after landing each flight), but there are quite a few digital options on the market now. I use one called LogTen, which stores everything in a SQLite file behind the scenes which is what I used to make this.

    What happens if you lose it?
    - markdown 1y ago
      You go back to every airline you ever worked for, beg for your flight logs, hope they are willing to provide them, and then over the course of weeks re-enter them into your paper logbook or software. Then you hope that the airline will also be willing to sign-off your logbook. TL;DR: you're screwed.

    You are only required to log time required for 61.51.a.1 or .a.2, but are not required to log “all [your] flying hours” by the FAA. (Your airline might require it and it’s a good idea to log all your flights, but it’s not a law.)
arccy 1y ago
I wonder if you can spread out the airport labels a bit when they're clustered together, like the cluster around CYOO in the US.
- jamesharding 1y ago
  Good idea! Not sure exactly how to do this with globe.gl but I will look into it.
jonlucc 1y ago
This is great data visualization of interesting data! I'm curious about the last graph; there seems to be something making some of the longest flights take more time/nm. Is that real or an artifact, and is there an explanation for the tail?
- jamesharding 1y ago
  Great question! It is not an anomaly, it is very geographically specific. Due the the Ukraine war (and my home base being in the UK), we have to fly the long way around to get to far-east destinations like Tokyo and Hong Kong. Flying outbound from London we have to fly down over Turkey (which adds about two hours of flight time). Flying home from Tokyo with the ongoing airspace closure, if the the weather is suitable at the ETOPS airports enroute, it is actually quicker to fly home eastbound again, flying up over Alaska. A proper around-the-world in 4 days!
  - rob74 1y ago
    So for London-Tokyo the return route is completely different from the outbound route? Fascinating! I guess that has something to do with the jetstream (which only helps you when travelling eastbound)?
    - jamesharding 1y ago
      Exactly that! This is the only route that I know of where this is the case. Looks like today’s flight home is following that route: https://uk.flightaware.com/live/flight/BAW8/history/20250629/0000Z/RJTT/EGLL https://uk.flightaware.com/live/flight/BAW8/history/20250629...

  Oh come on, lighten up a little, it's Friday, it's kinda cool as a display tool. should we reduce the number of flights and CO2 released? Of course. But no need to be rolling in on a guy that just did something neat...
  - lucasban 1y ago
    I’m also not sure how much sense it makes to talk about the personal carbon footprint of a pilot flying for their job, in terms of “could they make decisions that would change how much is released”

Having a computer engineering background, what motivated you to become a pilot and switch careers?
- iamspoilt 1y ago
  Looking at your projects, seems like you still have the hacker going in you! Saw Home Assistant one! Kudos!
  - jamesharding 1y ago
    Love Home Assistant! I have a screen on my split flap display that shows aircraft flying overhead our house (at very high level) - all fed by home assistant and various HACS addons.
- jamesharding 1y ago
  I had always been interested in aviation, and I was fortunate that I was in the right place at the right time after graduation to join an airline on a sponsored "cadet scheme". I still (hopefully evidently) very much love software/engineering, but I guess I chose the path of "professional pilot, hobbyist engineer" over the alternative of "professional engineer, hobbyist pilot".
  - joshvm 1y ago
    I'm surprised how wide the acceptance age range is for BA's program (18-55). Is it common for people to transfer from unrelated careers? Nice to know that door isn't technically shut for a while!
  - avgDev 1y ago
    I loved programming before doing it as a job. Now, I really can't be bothered to program outside of work. At what age did you make this change? I love medicine, researching diseases I hear about and learning about the body is hobby for me. I would love to get into it but I am almost 40.
mkoubaa 1y ago
Are you allowed to code while sitting in the cockpit but not actively flying?
- jamesharding 1y ago
  On the long flights where we carry more than two pilots, we have allocated break time away from the cockpit. During those breaks, you can do whatever you like (sleep, watch a film, read a book, etc). I tend to try to sleep on the plane, but I always bring my laptop on trips to work on projects while downroute. Especially on west-coast trips with the 8 hours timezone change, I am usually awake at 2am which is great for being productive!
  - walthamstow 1y ago
    I am insanely productive when programming on flights without wifi, provided I've cached what I needed to beforehand. Something about it just works
    - amelius 1y ago
      Ok, so no high-quality LLMs possible.
    - bschwindHN 1y ago
      I'm jealous - all that time sitting around to get something productive done, and I can't concentrate at all because I can't relax, the plane suddenly shakes and distracts me, and it feels like I'm lacking oxygen and am not thinking clearly. I remember trying to code some stupid iterator thing in Rust for a few hours and couldn't crack it. On the ground it was solved in like 10 minutes.

andreygrehov 1y ago
This is great work! I have a somewhat off-topic question. How are your ears? Do pilots have any tricks to save their ears from getting clogged due to the constant pressure changes? Second question. Would it be possible to predict flight delays based on the number of inbound and outbound flights?
- jamesharding 1y ago
  Thank you :) I haven't had issue with my ears (other than the occasional lingering cold), but usually a good yawn or chewing gum will clear it. On a normal day, I am fortunate to have wide eustacian tubes I guess!
- lbotos 1y ago
  Not a pilot but fly frequently -- A lot of the modern larger planes 787 Dreamliner or an A330/350 have something that helps with the ear clogging. I travel NY/LON a lot, and I rarely have any ear popping. If I travel on a smaller plane say NY -> Miami, I easily get the clogged feeling.
  - netsharc 1y ago
    The newer planes pressurize their cabin to a lower simulated altitude. https://aviation.stackexchange.com/questions/1728/does-the-b787-dreamliner-operate-with-higher-cabin-pressure https://aviation.stackexchange.com/questions/1728/does-the-b...
nelblu 1y ago
Love it :-). Do you also need to log the gps co-ordinates as you are flying? I would love to see how you avoid the airspace in the war hit areas.
- netsharc 1y ago
  Not OP, but commercial airliners fly on airways: https://www.youtube.com/watch?v=EwaYDVbQvKI& https://www.youtube.com/watch?v=EwaYDVbQvKI& , from waypoint to waypoint. When there's missiles in the air heading to land on innocent babies, the airlines choose waypoints so that they don't fly over these areas.
- jamesharding 1y ago
  I wish I had it! Our flight plans contain the full routes (waypoints and airways), but there is no easy way to capture this information. While not exact prohibited airspace, this map shows where GPS jamming is highest, which roughly corresponds to the warzones: https://gpsjam.org/ https://gpsjam.org/
ok_computer 1y ago
Cool visualization for your personal logbook. How is the raw or display data stored? The globe map reminds me of this hexagonal grid article from my bookmarks I’d found on here or reddit. https://www.redblobgames.com/grids/hexagons/ https://www.redblobgames.com/grids/hexagons/ As an airline pilot, I am curious, have you watched the season 2 of Nathan Fielder’s Rehearsal on HBO, that comically addresses the topic of pilot-copilot communication? If so what are your thoughts on his portrayal of the existence of copilot communication friction. And without intending to dig into your personal business, do you think there is a tendency and survivor (retention) bias for the profession to remain high functioning ______, without recognizing a need for help. Or is this portrayal of stunted coworker dialog an edge case that is amplified from his perspective.
- wetoastfood 1y ago
  > How is the raw or display data stored? He answered in the post that he uses LogTen Pro[1] which enables querying with SQL[2]. In the SQL post he says the app has an export for CSV but the app stores it in SQLite which you can access and query from directly.

- jamesharding 1y ago
  The data is all in a sqlite file from my logbook software! I wrote a little post about extracting the data here: https://jameshard.ing/posts/querying-logten-pilot-logbook-sql https://jameshard.ing/posts/querying-logten-pilot-logbook-sq... I have only seen a few clips from The Rehersal (the bit with Sully listening to Evanescence), so I don't have much to go on. Pilot communication is definitely something that we spend a lot of time talking about and training (under the larger banner of CRM - crew resource management), and in my experience the industry is making real efforts to be better in this area!

I'm curious to know what is the small concentrated cluster of flights Northwest of Dulles airport, where the flight durations seem way too high compared to the effective distance between the points.
- jamesharding 1y ago
  Those are all of my flights in light aircraft around my hometown in Canada! They fly a little bit slower than the A350 :) There is a similar cluster around the south of Spain where I completed my Commercial/ATPL training.

Those few days that show back-to-back 14hr days must have been an experience :) What's your favorite thing to see up in the sky and in the clouds?
- jamesharding 1y ago
  The 14 hour days certainly felt long! I think that seeing the northern lights (quite common on our flights to west-coast North America) or large thunderstorms over the equator at night (from a safe distance) are probably the highlights for me :) SpaceX launches are becoming more regular occurrences too!
jasonthorsness 1y ago
I love the sequential globe especially! For an idea - anything you could do with altitude? Your average height above sea level per day? I dunno :p
- NKosmatos 1y ago
  I’ll second this idea. Keeping track of your hours on high altitude is important sine you get more radiation than us on the ground. I’ve read various articles about pilots & flight attendants health affected by higher exposure to radiation.
  - willsmith72 1y ago
    True, but is it counterbalanced by their ageing at least a few microseconds more slowly thanks to spending so much time closer to the speed of light?
    - cyberax 1y ago
      You actually age faster on an airplane, because you are in a less dense space and experience less gravitational redshift. General relativity works against the Special Relativity in this case.

        Well shucks to my high school physics teacher
- jamesharding 1y ago
  I wish I had the data! Likewise, collecting the number of passengers carried would be a nice cumulative statistic at the end of my career (I guess I can start recording this when I become a Captain?)
  - FL410 1y ago
    You could (probably) pull the ADSB data for a "representative" flight on given routes and use that to at least get close - probably would still be useful for things like radiation exposure mentioned elsewhere. Otherwise, maybe you can get Claude to vibe code you a mobile app that runs in the background and collects all the interesting data (GPS, cabin alt, etc)

      I wish I wasn't medically barred from having a pilot's license. Not for the pay, but I just like the idea of flying. Unfortunately, I cannot. I recommend people use their salaries to learn how to fly regardless! It's maybe ~$15-20k to get a PPL which is doable for the tech crowd with some planning.
    - BrandoElFollito 1y ago
      I think GP meant some girls outside of software engineering. I would love to switch (back) to teaching but a 10x pay cut is not doable. Maybe close to retirement I will give it a try.

  Your handle is "supportengineer". Presumably you outrank OP if you count assists, or a share of others' successes. Do the developers of the libraries he used count this site as a personal accomplishment? Do the airplane mechanics? Do their support engineers? We participate in a circulatory economy, but we haven't yet adopted a perspective of circulatory attribution. Maybe we never will. Maybe we never should. Maybe you should recognize your piecemeal contributions as a sort of ikigai, or maybe you should see this as a wakeup call to carpe diem. Thanks for the opportunity to pontificate!
weinzierl 1y ago
That is beautiful. Besides the globe and the cool animations I like the dashboard that shows summary stats. This made me think. Either Frauenhofer or Helmholtz in Germany used to have a site where you could enter your specific flights and it would tell you your overall radiation exposure. This was meant mainly for flight personnel and it was not nearly as beautiful. The accumulated exposure would be a useful addition for the dashboard.
- jamesharding 1y ago
  A great idea! The company that I work for does actually provide us with our cumulative dosage data for the month/year/lifetime, but not at such a granular level. Do you know of any statistical way that I could calculate this? I suppose I could work out the great circle routes and the approximate dosage in that airspace at a given time?
  - defrost 1y ago
    For any third parties (I'm getting a wee bit old for these diversions) geophysical survey companies (the ones with crop dusters with stingers on their tails, high wing twin props with stingers and wing tips sensors, etc.) have ongoing globally spread about calibration flights for radiometric (environmental ground radiation) surveys. The surveys are (usually) 200m spaced grid lines 20km (or so) long flown 80m above ground, the calibration flights are stacked lines from quite high up down to ground level so that the post processing can estimate and subtract cosmic radiation "from above" and how it falls off through the current atmosphere (density, humidity, etc. thinning out current gamma inflow from up high). Such things, if accessed, would fine tune a radiometric exposure by height model in the same way that using the global magnetic model(s) (there are two main ones) can tune up true north magnetic readings .. it's a fine adjustment that only matters to some. Some working airport that your cross somewhere in the world likely has a hanger full of geophys survey craft (helicopters and planes) .. might be worth chasing up.

  do pilots get to mess around on a laptop while flying? My understanding is that most of a flight is just sitting there waiting for landing to start, could mean a lot of spare time to pick up programming
  - mbreese 1y ago
    I don’t think the cognitive context switching required would be a good fit. I imagine pilots always have to be “on” just in case something happens, even if they are letting the plane do some of the routine flying.

There seems to be some crossover between the software and flying 'communities'. Perhaps this is rather unsurprising given some of the shared prerequisite skills? Is it your experience there are many commercial pilots who code? Do you expect to get 100% of the way to the sun over your career?

ortusdux 1y ago
Very cool! Can you share any info on the 945min flight from back in June?
- jamesharding 1y ago
  Thank you! That flight was the return from Tokyo (RJTT) to London (EGLL). Due to the closure of Russian airspace, the outbound flight is longer than pre-war as we fly over Turkish airspace. Due to the wind patterns, it is almost always longer flying westbound, so we usually fly east both ways. In this case, the weather at one of the ETOPS alternates that we use (Shemya, https://en.wikipedia.org/wiki/Eareckson_Air_Station https://en.wikipedia.org/wiki/Eareckson_Air_Station) was out of limits, so we had to fly back Westbound with the associated headwind and longer flight time.

halilkoklu 1y ago
Inspiring profile with beautiful charts. Glad to have found someone else with a similar background who decided to fly jets. I had a good run as a software engineer and executive for the last 20 years. I have just completed my Airbus 320 type rating waiting for my base check. I will be flying for a national flag carrier.
- jamesharding 1y ago
  Congratulations, and thank you! I moved from the A320 to the A350 just over two years ago, and they are remarkably similar to fly (by design)! I would go so far as saying that you could hop in the A350 sim with zero training, and you would be able to operate it to a safe standard.
  - halilkoklu 1y ago
    I've got my eyes on the A350 for ages now so I'm glad that I landed on the Airbus fleet (80/20 odds in favour of Boeing here at my airline). I've got two possible progression tracks from here: 1. gain experience on the A320 for a year, get upgraded to the A330, after two years get certified for the A350 to fly A330/A350 mixed. 2. spend years on A320, upgrade to captain, many more years, then finally upgrade to A330 as captain, then two years later A350 added. I am planning to fly jump seat to see all the types we're flying.
    - jamesharding 1y ago
      May I ask which airline you fly for? Feel free to email me if you like (email is on the website!) if you'd rather not post it in public :) Career progression in airlines is interesting - with lifestyle being so heavily influenced by seniority at most airlines, there is often a big tradeoff decision to make between lifestyle and salary. At my current airline, the most well-trodden career progression has historically always been Short-haul FO -> Long-haul FO -> Short-haul Captain -> Long-haul Captain. Curious if this is the same at other airlines?

I'm flying your most recent route next month(ba218). If I see you I'm going to say something weird, like "I know where you've been flying James". I hope that's okay. Regarding ideas, I noticed that you use great circle distance in some of your measurements, what about getting the actual flight data, and the graph showing deviation of your flight from the ideal.
- jamesharding 1y ago
  Haha, if there is another James flying the plane, they might be spooked! I'm not flying to Denver for until at least August based on my current roster. It would be great to use the actual distances (and would help me lap the moon a few more times), but there is no easy way to get the data. Our company flight plans which contain the actual route are in PDF format and with no easy API, and EuroControl (who hold the filed flight plans) charge quite a bit to have access I believe. I supposed I could screenshot the route and upload it to my server and have it OCR the route!

If I understand OP journey, was he fortunate to have been scholarship to fund his studies to become a pilot? I was looking into pilot school here and they cost upwards to $100k
- jamesharding 1y ago
  Exactly this. When I joined, the company offered a cadet scheme where the company would underwrite the loan required for your pilot training (84,000 GBP in 2016), and then that amount was repaid to us over 84 months of employment (while on a reduced cadet salary). It essentially spread the cost of training out over 7 years. The current cadet scheme is better in the sense that you do not have to take on a personal loan for the flight training!

voxleone 1y ago
Very cool. I just wanted to say how much I enjoyed reading through your detailed flight logs — the way you’ve documented your experience, from distances and time in the air to the nuances of roles (P1, P2, PICUS), was fascinating. As someone concerned with these matters — developing SpinStep, a quaternion-based library for modeling orientation and vector state evolution in physical systems — I found myself unexpectedly inspired by your data. It got me thinking: could these kinds of spatiotemporal logs, with their emphasis on direction, roles, and environmental influences, be approached through something like rotational state modeling? For example: .Aircraft headings and orientation changes could map naturally to quaternions. .Role transitions (e.g. P1 ↔ P2) resemble discrete state changes within a continuous system. .Wind effects or flight network patterns might even be modeled as external fields influencing orientation over time. I hadn’t envisioned SpinStep in this context, but your log offered a compelling perspective. Whether or not it leads to something concrete, I just wanted to thank you for the inspiration. .https://github.com/VoxleOne/SpinStep/blob/main/README.md https://github.com/VoxleOne/SpinStep/blob/main/README.md \ .https://github.com/VoxleOne/SpinStep/blob/main/docs/01-rationale.md https://github.com/VoxleOne/SpinStep/blob/main/docs/01-ratio...
- jampekka 1y ago
  The repo reads a bit LLM written. Quaternions have some nice properties for some operations with 3D rotations, but they are not a panacea.
jakub_g 1y ago
If you're interested in the subject, let me introduce you to GCMap. GCMap can plot a line between any two IATA airport codes; actually you can put arbitrary number of pairs comma separated; and best of all, they can be passed as a URL param. For example: `JFK-LHR,LHR-CDG,CDG-FRA` http://www.gcmap.com/mapui?P=JFK-LHR,LHR-CDG,CDG-FRA http://www.gcmap.com/mapui?P=JFK-LHR,LHR-CDG,CDG-FRA I track my own flights by sending an email to myself with a GCMap URL every now and then.
- kccqzy 1y ago
  GCMap doesn't have a whole lot of different map projections to choose from. Having more than one pair on a single map will result in a pretty bad map projection. That's my biggest complaint. They really need to add more better projections such as Mollweide, Winkel Tripel, Robinson, etc. Or they should just have a globe.

So cool! I assumed that pilots just generally flew the same hops back and forth over and over, but it seems at first glance that there is actually a lot of variety. Does it make you nervous when you have to land in a new place for the first time?
- jamesharding 1y ago
  I guess the variety of flights is based on which aircraft one flies! I flew the A320 for the first 6 years, which covered all of Europe and a little bit of North Africa (Egypt, Lebanon, Jordan). Now flying the A350, there is more of the world unlocked, but there are still some routes that only other aircraft (777/787/A380) fly at my company. We have comprehensive company data for each airport that we operate to, and some of the more challenging airports have special training (in the simulator) as a requirement, or a video briefing. Nervous would be the wrong word, but it is always exciting to fly somewhere new!
HeavenFox 1y ago
Very cool! As a semi-frequent flyer I am also passionate about logging every flight I have taken. I have been using OpenFlights for the last five years but the constant bugs always bugged me :) This year I finally decided to build my own: https://jetsetter.quest https://jetsetter.quest
poly2it 1y ago
Very interesting visualisations! I'm surprised but at the same time not surprised at the apparent overlap between pilots and programmers. Do you have a favourite/least favourite plane to fly, or are they all the same?
- jamesharding 1y ago
  Slightly biased, but right now I am really enjoying the A350! There are a few "gadgets" that really improve the QoL for pilots (moving map on the ground, camera in the tail for taxiing on the ground, much improved safety systems for situations like blocked pitot tubes, etc).
aitacobell 1y ago
Super cool. Harkens back to days of Microsoft Flight Simulator
b0a04gl 1y ago
when a route doesn't come back as a roundtrip , like you fly LHR > HKG but not the return . how does that usually get handled on your end? do you deadhead back, get reassigned regionally or wait out a layover cycle?
- jamesharding 1y ago
  Good question! There are a few routes in my data where the outbound and inbound sectors don't match for this exact reason. Since almost all of our flights begin and end at LHR, if a flight is cancelled we either operate the flight the following day, or fet "positioned" (our word for deadhead) home as a passenger. Usually when a route changes aircraft, there is a requirement to "position" some pilots out a few days before as passengers to bring the aircraft home when it lands there for the first time. Logistically, very complex!
intalentive 1y ago
Cool. It would be neat to see velocity and altitude too.
aquafox 1y ago
I would plot the destination matrix as a jeatap where each row is a departure and each column an arrival and color is the number of trips. Additionally, you could cluster the rows and columns of this heatmap.
joemi 1y ago
Nice metrics and visualizations! The kind of graph you used for the destination matrix doesn't always feel very useful, but in this case it worked really well. One thing I immediately thought to check after seeing your hours graph was what percentage of the year you were in flight (or in a plane, I guess). For your peak year (2024), it worked out to be about 8.7% of the year! It probably even higher if you just count your waking hours, but I don't know your sleep habits or how many of your flights you might have slept during.
- jamesharding 1y ago
  You did the math! Thank you :) It is one of the pecularities of the job, in that I will be "at work" for 4 days, but only actually strapped into an airplane for 8-14 hours at the beginning and end of that - the rest is mandated (and much needed) resting.
schubart 1y ago
Do all your flights start or end in London?
- jamesharding 1y ago
  Almost all, but not quite all! For example, about 6 months ago, I operated the following trip pattern: LHR -> GIG -> EZE -> GIG -> LHR The Rio to Buenos Aires and back "shuttle" flight was a day of flying on its own, with 24 hours rest afterwards before flying back to London.
frenchman_in_ny 1y ago
Very cool. One nit is because of the graph smoothing, it looks like you have negative hours P2 time 2014-2015 and Heavy time 2021-2022. I thought the ICAO "Heavy" designation applied to aircraft above a certain MTOW instead of time? Wouldn't the time designation be as acting as relief captain/FO? In any case, great visualizations.
- jamesharding 1y ago
  The term "Heavy" (for wake separation) in the ICAO context is 100% based on MTOW! In the context of this graph, these are flights where we carry 3 or 4 pilots, and I am not in the seat for takeoff or landing. We still operate at the control during the middle of the flight when the other pilots are on their rest break. Not sure where the name "Heavy" came from here, but is it just the term used at my airline (and probably others? Some use "relief crew") Good call on the data smoothing - I will look into a fix for this!

kinow 1y ago
Amazing visualization. Any plans to add more features to each log? e.g. difficulty of taking-off/flying to/landing, or trajectory with/out turbulence, etc.?
- jamesharding 1y ago
  Thank you! I have text comments/remarks for all particularly memorable flights (for all of the above reasons you mentioned, plus famous passengers, family on board, etc), but some of those are quite private and also difficult to show in a visualisation like this. I would love to track more data over time, but balancing that with it being easy to collect is the challenge!
  - pcollins123 1y ago
    You could summarize that data using some form of machine learning. A good new skill to develop. Then you don’t need to share the exact details, just a count per category. E.g. personal incident (32), late take off duty to X (23), passenger medical incident (15). Hopefully in aggregate form that data is less of a privacy issue and less of a commercial risk for your company.
drpizzamd 1y ago
just out of sick curiosity...something about flights with ill-behaved fliers. Ultimately, as one who does not work in the airline business and has flown often, how often are pilots and staff perturbed by customers?
- jamesharding 1y ago
  I have only had very few incident with ill-behaved passengers, and none that escalated. Ill passengers is a different story, especially on longer flights! With no hard data to back this up, I think that medical emergencies are probably the most common form of abnormal event that we encounter.
jbergler 1y ago
Very neat, something that would be cool to see is the commercial vs GA split over time. In your graph by type it’s quite hard to see how much flying you still do on your own time!
- jamesharding 1y ago
  I do actually have my GA flying included in this data, it’s just pretty minimal these days! GA flying is very expensive in the UK. I still fly our family airplane when I am home in Canada, but it only amounts to a few hours a year. You can see the flight time for “7KCAB” very slowly trickling up in the cumulative time graph at the bottom.
  - jbergler 1y ago
    Oh cool, neat plane to have! And on desktop that's definitely easier to see than on mobile.

Should add the amount of CO2 emissions per flight since you know the model of plane(s). And if you have occupancy data for each flight, can even determine efficiency.

This is awesome and I love it. Thanks for sharing! I'm just wondering what made you wanna be a pilot instead of sticking with a regular software engineering career, especially since you’ve got a degree in that and, of course, your talent here :)
- jamesharding 1y ago
  Thanks! My father being a pilot certainly played a large part, not in the sense that he forced me into it, but rather that I had the opportunity to sit on the jump seat as a kid (pre-9/11) and it planted the seed quite early. After finishing my degree, British Airways had opened their cadet pilot scheme - windows of opportunity like that are usually short and infrequent, so I went for it! The nice this is that I can still code and keep up on the software engineering trends (what I tell myself while checking HN for the n-th time in a day) on the side, and I think it is also a safe set of skills to have in case I can no longer fly (pandemics, losing my medical, etc)

alabhyajindal 1y ago

Very cool! I didn't know pilots are required to maintain a logbook. What's the official recommendation for this - using a paper logbook?

jamesharding 1y ago
Each country has slightly different requirements! For the US, here is the FAA rule for it: https://www.ecfr.gov/current/title-14/chapter-I/subchapter-D/part-61/subpart-A/section-61.51 https://www.ecfr.gov/current/title-14/chapter-I/subchapter-D... A lot of people still use paper (and fill it in after landing each flight), but there are quite a few digital options on the market now. I use one called LogTen, which stores everything in a SQLite file behind the scenes which is what I used to make this.
- pinoy420 1y ago
  What happens if you lose it?
  - markdown 1y ago
    You go back to every airline you ever worked for, beg for your flight logs, hope they are willing to provide them, and then over the course of weeks re-enter them into your paper logbook or software. Then you hope that the airline will also be willing to sign-off your logbook. TL;DR: you're screwed.

- sokoloff 1y ago
  You are only required to log time required for 61.51.a.1 or .a.2, but are not required to log “all [your] flying hours” by the FAA. (Your airline might require it and it’s a good idea to log all your flights, but it’s not a law.)

arccy 1y ago

I wonder if you can spread out the airport labels a bit when they're clustered together, like the cluster around CYOO in the US.

jonlucc 1y ago

This is great data visualization of interesting data! I'm curious about the last graph; there seems to be something making some of the longest flights take more time/nm. Is that real or an artifact, and is there an explanation for the tail?

jamesharding 1y ago
Great question! It is not an anomaly, it is very geographically specific. Due the the Ukraine war (and my home base being in the UK), we have to fly the long way around to get to far-east destinations like Tokyo and Hong Kong. Flying outbound from London we have to fly down over Turkey (which adds about two hours of flight time). Flying home from Tokyo with the ongoing airspace closure, if the the weather is suitable at the ETOPS airports enroute, it is actually quicker to fly home eastbound again, flying up over Alaska. A proper around-the-world in 4 days!
- rob74 1y ago
  So for London-Tokyo the return route is completely different from the outbound route? Fascinating! I guess that has something to do with the jetstream (which only helps you when travelling eastbound)?
  - jamesharding 1y ago
    Exactly that! This is the only route that I know of where this is the case. Looks like today’s flight home is following that route: https://uk.flightaware.com/live/flight/BAW8/history/20250629/0000Z/RJTT/EGLL https://uk.flightaware.com/live/flight/BAW8/history/20250629...

mkoubaa 1y ago

Are you allowed to code while sitting in the cockpit but not actively flying?

jamesharding 1y ago
On the long flights where we carry more than two pilots, we have allocated break time away from the cockpit. During those breaks, you can do whatever you like (sleep, watch a film, read a book, etc). I tend to try to sleep on the plane, but I always bring my laptop on trips to work on projects while downroute. Especially on west-coast trips with the 8 hours timezone change, I am usually awake at 2am which is great for being productive!

This is great work! I have a somewhat off-topic question. How are your ears? Do pilots have any tricks to save their ears from getting clogged due to the constant pressure changes? Second question. Would it be possible to predict flight delays based on the number of inbound and outbound flights?

jamesharding 1y ago
Thank you :) I haven't had issue with my ears (other than the occasional lingering cold), but usually a good yawn or chewing gum will clear it. On a normal day, I am fortunate to have wide eustacian tubes I guess!
lbotos 1y ago
Not a pilot but fly frequently -- A lot of the modern larger planes 787 Dreamliner or an A330/350 have something that helps with the ear clogging. I travel NY/LON a lot, and I rarely have any ear popping. If I travel on a smaller plane say NY -> Miami, I easily get the clogged feeling.

Not OP, but commercial airliners fly on airways: https://www.youtube.com/watch?v=EwaYDVbQvKI& https://www.youtube.com/watch?v=EwaYDVbQvKI& , from waypoint to waypoint. When there's missiles in the air heading to land on innocent babies, the airlines choose waypoints so that they don't fly over these areas.
jamesharding 1y ago
I wish I had it! Our flight plans contain the full routes (waypoints and airways), but there is no easy way to capture this information.

Cool visualization for your personal logbook. How is the raw or display data stored? The globe map reminds me of this hexagonal grid article from my bookmarks I’d found on here or reddit. https://www.redblobgames.com/grids/hexagons/ https://www.redblobgames.com/grids/hexagons/ As an airline pilot, I am curious, have you watched the season 2 of Nathan Fielder’s Rehearsal on HBO, that comically addresses the topic of pilot-copilot communication? If so what are your thoughts on his portrayal of the existence of copilot communication friction. And without intending to dig into your personal business, do you think there is a tendency and survivor (retention) bias for the profession to remain high functioning ______, without recognizing a need for help. Or is this portrayal of stunted coworker dialog an edge case that is amplified from his perspective.

I love the sequential globe especially! For an idea - anything you could do with altitude? Your average height above sea level per day? I dunno :p

I’ll second this idea. Keeping track of your hours on high altitude is important sine you get more radiation than us on the ground. I’ve read various articles about pilots & flight attendants health affected by higher exposure to radiation.
- willsmith72 1y ago
  True, but is it counterbalanced by their ageing at least a few microseconds more slowly thanks to spending so much time closer to the speed of light?

    You actually age faster on an airplane, because you are in a less dense space and experience less gravitational redshift. General relativity works against the Special Relativity in this case.

  You could (probably) pull the ADSB data for a "representative" flight on given routes and use that to at least get close - probably would still be useful for things like radiation exposure mentioned elsewhere. Otherwise, maybe you can get Claude to vibe code you a mobile app that runs in the background and collects all the interesting data (GPS, cabin alt, etc)

Sometimes I wish software development didn’t pay so exceptionally well. I’m interested in so many other things, but it’s hard to justify switching to another full-time field, knowing it would mean a significant pay cut.

    I wish I wasn't medically barred from having a pilot's license. Not for the pay, but I just like the idea of flying. Unfortunately, I cannot. I recommend people use their salaries to learn how to fly regardless! It's maybe ~$15-20k to get a PPL which is doable for the tech crowd with some planning.

That is beautiful. Besides the globe and the cool animations I like the dashboard that shows summary stats. This made me think. Either Frauenhofer or Helmholtz in Germany used to have a site where you could enter your specific flights and it would tell you your overall radiation exposure. This was meant mainly for flight personnel and it was not nearly as beautiful. The accumulated exposure would be a useful addition for the dashboard.

jamesharding 1y ago
A great idea! The company that I work for does actually provide us with our cumulative dosage data for the month/year/lifetime, but not at such a granular level. Do you know of any statistical way that I could calculate this? I suppose I could work out the great circle routes and the approximate dosage in that airspace at a given time?
- defrost 1y ago
  For any third parties (I'm getting a wee bit old for these diversions) geophysical survey companies (the ones with crop dusters with stingers on their tails, high wing twin props with stingers and wing tips sensors, etc.) have ongoing globally spread about calibration flights for radiometric (environmental ground radiation) surveys. The surveys are (usually) 200m spaced grid lines 20km (or so) long flown 80m above ground, the calibration flights are stacked lines from quite high up down to ground level so that the post processing can estimate and subtract cosmic radiation "from above" and how it falls off through the current atmosphere (density, humidity, etc. thinning out current gamma inflow from up high). Such things, if accessed, would fine tune a radiometric exposure by height model in the same way that using the global magnetic model(s) (there are two main ones) can tune up true north magnetic readings .. it's a fine adjustment that only matters to some. Some working airport that your cross somewhere in the world likely has a hanger full of geophys survey craft (helicopters and planes) .. might be worth chasing up.

Very cool! Can you share any info on the 945min flight from back in June?

jamesharding 1y ago
Thank you! That flight was the return from Tokyo (RJTT) to London (EGLL). Due to the closure of Russian airspace, the outbound flight is longer than pre-war as we fly over Turkish airspace. Due to the wind patterns, it is almost always longer flying westbound, so we usually fly east both ways. In this case, the weather at one of the ETOPS alternates that we use (Shemya, https://en.wikipedia.org/wiki/Eareckson_Air_Station https://en.wikipedia.org/wiki/Eareckson_Air_Station) was out of limits, so we had to fly back Westbound with the associated headwind and longer flight time.

Inspiring profile with beautiful charts. Glad to have found someone else with a similar background who decided to fly jets. I had a good run as a software engineer and executive for the last 20 years. I have just completed my Airbus 320 type rating waiting for my base check. I will be flying for a national flag carrier.

jamesharding 1y ago
Congratulations, and thank you! I moved from the A320 to the A350 just over two years ago, and they are remarkably similar to fly (by design)! I would go so far as saying that you could hop in the A350 sim with zero training, and you would be able to operate it to a safe standard.
- halilkoklu 1y ago
  I've got my eyes on the A350 for ages now so I'm glad that I landed on the Airbus fleet (80/20 odds in favour of Boeing here at my airline). I've got two possible progression tracks from here: 1. gain experience on the A320 for a year, get upgraded to the A330, after two years get certified for the A350 to fly A330/A350 mixed. 2. spend years on A320, upgrade to captain, many more years, then finally upgrade to A330 as captain, then two years later A350 added. I am planning to fly jump seat to see all the types we're flying.
  - jamesharding 1y ago
    May I ask which airline you fly for? Feel free to email me if you like (email is on the website!) if you'd rather not post it in public :) Career progression in airlines is interesting - with lifestyle being so heavily influenced by seniority at most airlines, there is often a big tradeoff decision to make between lifestyle and salary. At my current airline, the most well-trodden career progression has historically always been Short-haul FO -> Long-haul FO -> Short-haul Captain -> Long-haul Captain. Curious if this is the same at other airlines?

I'm flying your most recent route next month(ba218). If I see you I'm going to say something weird, like "I know where you've been flying James". I hope that's okay. Regarding ideas, I noticed that you use great circle distance in some of your measurements, what about getting the actual flight data, and the graph showing deviation of your flight from the ideal.

jamesharding 1y ago
Haha, if there is another James flying the plane, they might be spooked! I'm not flying to Denver for until at least August based on my current roster. It would be great to use the actual distances (and would help me lap the moon a few more times), but there is no easy way to get the data. Our company flight plans which contain the actual route are in PDF format and with no easy API, and EuroControl (who hold the filed flight plans) charge quite a bit to have access I believe. I supposed I could screenshot the route and upload it to my server and have it OCR the route!

Exactly this. When I joined, the company offered a cadet scheme where the company would underwrite the loan required for your pilot training (84,000 GBP in 2016), and then that amount was repaid to us over 84 months of employment (while on a reduced cadet salary). It essentially spread the cost of training out over 7 years. The current cadet scheme is better in the sense that you do not have to take on a personal loan for the flight training!

voxleone 1y ago

Very cool. I just wanted to say how much I enjoyed reading through your detailed flight logs — the way you’ve documented your experience, from distances and time in the air to the nuances of roles (P1, P2, PICUS), was fascinating. As someone concerned with these matters — developing SpinStep, a quaternion-based library for modeling orientation and vector state evolution in physical systems — I found myself unexpectedly inspired by your data. It got me thinking: could these kinds of spatiotemporal logs, with their emphasis on direction, roles, and environmental influences, be approached through something like rotational state modeling? For example: .Aircraft headings and orientation changes could map naturally to quaternions. .Role transitions (e.g. P1 ↔ P2) resemble discrete state changes within a continuous system. .Wind effects or flight network patterns might even be modeled as external fields influencing orientation over time. I hadn’t envisioned SpinStep in this context, but your log offered a compelling perspective. Whether or not it leads to something concrete, I just wanted to thank you for the inspiration. .https://github.com/VoxleOne/SpinStep/blob/main/README.md https://github.com/VoxleOne/SpinStep/blob/main/README.md \ .https://github.com/VoxleOne/SpinStep/blob/main/docs/01-rationale.md https://github.com/VoxleOne/SpinStep/blob/main/docs/01-ratio...

The repo reads a bit LLM written. Quaternions have some nice properties for some operations with 3D rotations, but they are not a panacea.

jakub_g 1y ago

If you're interested in the subject, let me introduce you to GCMap. GCMap can plot a line between any two IATA airport codes; actually you can put arbitrary number of pairs comma separated; and best of all, they can be passed as a URL param. For example: `JFK-LHR,LHR-CDG,CDG-FRA` http://www.gcmap.com/mapui?P=JFK-LHR,LHR-CDG,CDG-FRA http://www.gcmap.com/mapui?P=JFK-LHR,LHR-CDG,CDG-FRA I track my own flights by sending an email to myself with a GCMap URL every now and then.

kccqzy 1y ago
GCMap doesn't have a whole lot of different map projections to choose from. Having more than one pair on a single map will result in a pretty bad map projection. That's my biggest complaint. They really need to add more better projections such as Mollweide, Winkel Tripel, Robinson, etc. Or they should just have a globe.

piker 1y ago

So cool! I assumed that pilots just generally flew the same hops back and forth over and over, but it seems at first glance that there is actually a lot of variety. Does it make you nervous when you have to land in a new place for the first time?

jamesharding 1y ago
I guess the variety of flights is based on which aircraft one flies! I flew the A320 for the first 6 years, which covered all of Europe and a little bit of North Africa (Egypt, Lebanon, Jordan). Now flying the A350, there is more of the world unlocked, but there are still some routes that only other aircraft (777/787/A380) fly at my company. We have comprehensive company data for each airport that we operate to, and some of the more challenging airports have special training (in the simulator) as a requirement, or a video briefing. Nervous would be the wrong word, but it is always exciting to fly somewhere new!

HeavenFox 1y ago

poly2it 1y ago

Very interesting visualisations! I'm surprised but at the same time not surprised at the apparent overlap between pilots and programmers. Do you have a favourite/least favourite plane to fly, or are they all the same?

jamesharding 1y ago
Slightly biased, but right now I am really enjoying the A350! There are a few "gadgets" that really improve the QoL for pilots (moving map on the ground, camera in the tail for taxiing on the ground, much improved safety systems for situations like blocked pitot tubes, etc).

aitacobell 1y ago

Super cool. Harkens back to days of Microsoft Flight Simulator

b0a04gl 1y ago

when a route doesn't come back as a roundtrip , like you fly LHR > HKG but not the return . how does that usually get handled on your end? do you deadhead back, get reassigned regionally or wait out a layover cycle?

jamesharding 1y ago
Good question! There are a few routes in my data where the outbound and inbound sectors don't match for this exact reason. Since almost all of our flights begin and end at LHR, if a flight is cancelled we either operate the flight the following day, or fet "positioned" (our word for deadhead) home as a passenger. Usually when a route changes aircraft, there is a requirement to "position" some pilots out a few days before as passengers to bring the aircraft home when it lands there for the first time. Logistically, very complex!

intalentive 1y ago

Cool. It would be neat to see velocity and altitude too.

aquafox 1y ago

I would plot the destination matrix as a jeatap where each row is a departure and each column an arrival and color is the number of trips. Additionally, you could cluster the rows and columns of this heatmap.

joemi 1y ago

Nice metrics and visualizations! The kind of graph you used for the destination matrix doesn't always feel very useful, but in this case it worked really well. One thing I immediately thought to check after seeing your hours graph was what percentage of the year you were in flight (or in a plane, I guess). For your peak year (2024), it worked out to be about 8.7% of the year! It probably even higher if you just count your waking hours, but I don't know your sleep habits or how many of your flights you might have slept during.

jamesharding 1y ago
You did the math! Thank you :) It is one of the pecularities of the job, in that I will be "at work" for 4 days, but only actually strapped into an airplane for 8-14 hours at the beginning and end of that - the rest is mandated (and much needed) resting.

schubart 1y ago

Do all your flights start or end in London?

jamesharding 1y ago
Almost all, but not quite all! For example, about 6 months ago, I operated the following trip pattern: LHR -> GIG -> EZE -> GIG -> LHR The Rio to Buenos Aires and back "shuttle" flight was a day of flying on its own, with 24 hours rest afterwards before flying back to London.

frenchman_in_ny 1y ago

Very cool. One nit is because of the graph smoothing, it looks like you have negative hours P2 time 2014-2015 and Heavy time 2021-2022. I thought the ICAO "Heavy" designation applied to aircraft above a certain MTOW instead of time? Wouldn't the time designation be as acting as relief captain/FO? In any case, great visualizations.

jamesharding 1y ago
The term "Heavy" (for wake separation) in the ICAO context is 100% based on MTOW! In the context of this graph, these are flights where we carry 3 or 4 pilots, and I am not in the seat for takeoff or landing. We still operate at the control during the middle of the flight when the other pilots are on their rest break. Not sure where the name "Heavy" came from here, but is it just the term used at my airline (and probably others? Some use "relief crew") Good call on the data smoothing - I will look into a fix for this!

I would love to track more data over time, but balancing that with it being easy to collect is the challenge!
- pcollins123 1y ago
  You could summarize that data using some form of machine learning. A good new skill to develop. Then you don’t need to share the exact details, just a count per category. E.g. personal incident (32), late take off duty to X (23), passenger medical incident (15). Hopefully in aggregate form that data is less of a privacy issue and less of a commercial risk for your company.

drpizzamd 1y ago

just out of sick curiosity...something about flights with ill-behaved fliers. Ultimately, as one who does not work in the airline business and has flown often, how often are pilots and staff perturbed by customers?

jamesharding 1y ago
I have only had very few incident with ill-behaved passengers, and none that escalated. Ill passengers is a different story, especially on longer flights! With no hard data to back this up, I think that medical emergencies are probably the most common form of abnormal event that we encounter.

jbergler 1y ago

Very neat, something that would be cool to see is the commercial vs GA split over time. In your graph by type it’s quite hard to see how much flying you still do on your own time!

jamesharding 1y ago
I do actually have my GA flying included in this data, it’s just pretty minimal these days! GA flying is very expensive in the UK. I still fly our family airplane when I am home in Canada, but it only amounts to a few hours a year. You can see the flight time for “7KCAB” very slowly trickling up in the cumulative time graph at the bottom.

jamesharding 1y ago
Thanks! My father being a pilot certainly played a large part, not in the sense that he forced me into it, but rather that I had the opportunity to sit on the jump seat as a kid (pre-9/11) and it planted the seed quite early. After finishing my degree, British Airways had opened their cadet pilot scheme - windows of opportunity like that are usually short and infrequent, so I went for it! The nice this is that I can still code and keep up on the software engineering trends (what I tell myself while checking HN for the n-th time in a day) on the side, and I think it is also a safe set of skills to have in case I can no longer fly (pandemics, losing my medical, etc)

  here's what the last three months of retirement travel look like: https://share.icloud.com/photos/0bfsKT8PAv_CxDl4pVRWe9-iQ https://share.icloud.com/photos/0bfsKT8PAv_CxDl4pVRWe9-iQ Among many cool experiences was taking "Le Shuttle" under the English Channel - it's perhaps the most impressive piece of civil engineering I've seen.

If you want something similar for yourself personally, I've found Flighty on iOS to be amazing https://apps.apple.com/us/app/flighty-live-flight-tracker/id1358823008 https://apps.apple.com/us/app/flighty-live-flight-tracker/id...

Noticed the last logged flight is KDEN>EGLL. I do that KDEN<>EGLL route many times per year, sometimes multiple per month. I wonder if I’m ever on a flight with James :) Will have to listen out!

If you ever hear my name on the PA, please come up to say hello! In fact, after the flight when it is not busy, we are always happy to have visitors in the flight deck. Feel free to drop me a message any time too, the A350 is a pretty small fleet, so the chances are higher than one would think! :)

I love what you've done with your logbook, but the coolest part of the page was the photo of you on the flight deck with your Dad. I'm an airline pilot here in the US and it would be the privilege of a lifetime to be able to do that with one of my kids.

It truly has been the career highlight for me! He will be retiring in a few months, so we have the last flight together planned aleady. Hopefully you will be able to have the same experience with your kids! What fleet are you on currently?

  I fly the mighty Bombardier CRJ for a certain Utah-based regional airline in the US :)

That destination matrix is something I’ve never seen before!

That's a super cool way to visualize your career! Did you use a specific mapping library or build something custom?
