100% of ultimate load, which is 150% of limit load. The limit load is what goes into the flight manuals and is what the aircraft is certified to withstand. The ultimate load is a safety factor on top of limit load and is what the engineers

I loathe this term. It’s like they’re shifting the blame for ineffective treatments onto the depression. If the treatments don’t work, the problem is with the treatments. Come up with something else!

It’s rhetorical.

A TTC is a TrueType Collection. Multiple fonts in one file. Instead of having separate files for every size, weight, etc. they’re combined into one. The major advantage is the ability to share glyphs between fonts instead of duplicating inf

I’ve heard this idea a lot and it always strikes me as one of those things that’s technically true but wildly off base. I get that the equations are mathematically reversible. Presumably we’re more interested in the world than we are the ma

Order matters in English , because it lost its Germanic declensions. In highly inflected languages order is less relevant to meaning.

UTC != Unix time. UTC is a standard by which time is measured, independent of any particular representation. Unix time is one way of representing or encoding a given point in time.

You can have as many type ratings as will fit on your certificate. Company policies limit pilots to one or two types at a time, depending on the company.

Oh, bummer. That would’ve been a fun case study if it had been true.

IIRC there was a bug in an early version of a certain fighter jet where it would go inverted when crossing the equator. Oops.

Some cultures end the day at (wait for it...) sunset. And now we're back to the original problem.

And it's a reminder that "edge case" is relative. It's not an edge case for people who live there!

Well that's almost enough to make one think daylight saving time is a bunch of cracked-up nonsense!

Indeed. Christopher Hitchens called himself not just an atheist, but an "anti-theist."

You're teetering on the brink of an epiphany there with the phrase "in our society." Being a night owl wasn't a problem until we built a world that didn't include us. The problem isn't night owls. It's the

Depends on whether your parachute is integral to the seat or you’re wearing a pack. If the chute is in the seat, I would highly recommend staying harnessed to it.

Less than the chance of the original emergency killing you! That’s what the full trim is for. It makes the aircraft pitch away once you let go of the stick.

I flew an L-39 with inoperative ejection rockets. The bailout procedure was: 1. Roll inverted. 2. Trim full nose down. (Down = skyward at this point.) 3. Blow canopy. 4. Fall out.

I was once a fervent devotee of semver. It's so predictable! It's structured! There's a system! Everyone loves a system, especially engineers. I've since become disillusioned. The problem with semver, in my experience,

The Arctic includes parts of Alaska, Russia, Greenland, and Scandinavia. It’s not just ocean. Greenland’s ice cap is melting too, and China (for one) is very interested in mining there. https://www.nytimes.com/2012/09&#

No, they meant the Arctic. The sea ice covering the Arctic has a natural cycle of growth and retreat with the seasons, but the overall trend in the last decade is one of unprecedented decline. This has led countries like Russia, Canada, and

Ah, thanks for the clarification. From an engineering perspective that makes total sense - and is disastrous from the pilot's perspective!

Indeed. And it goes to show that rejecting “impossible” values is a dangerous strategy.

Critically in that case, the stall warning stopped when the nose was pulled up even further, because the computers rejected the indication as too large to be correct. So every time the nose was lowered, the stall warning activated .

What speed is that? I don’t know about 737s in particular but some AoA sensors work at speeds as low as 20 knots—far less than V1 on any runway a 73 is going to use.

Autopilots run the gamut from simple wing-levelers to fully automated departures, en route navigation, arrival procedures, landings, and runway rollouts. You'd be amazed what even a light piston single-engine can pack. Just today I fle

Theoretically it’s possible that both AoA vanes could ice over, but that would mean failure of both vanes’ heating elements. (Not a jet pilot myself but I teach instrument and charter pilots, and I’m in the clouds a lot!)

I'm not typed either, for the record. Current flight instructor and my boss is a check airman at a major--that's about all I've got to offer. :) As I understand it there's a potentially dangerous pitch-up moment that occ
