They use these kinds of transponders for TCAS (traffic collision avoidance system), so yes, it should be plain text if you like planes not crashing in to each other...
- dagw 11y agoIsn't position and velocity (and acceleration?) enough for TCAS? Why do you need full identity and flightplan for the aircrafts?
- jMyles 11y agoI think the problem is that some of us aren't up to speed on the particulars. Is that what's being blocked (and proposed for encryption)? Just the "full identity and flightplan"?
- ce4 11y agoFlight history of blocked aircraft is inaccessible as well. E.g. executives may not want to reveal insightful flights. E.g. American Airlines AA1 recent flight history: http://www.flightradar24.com/data/flights/aa1/ http://www.flightradar24.com/data/flights/aa1/

- vwcx 11y agoSure, but why should we be biasing the maintenance of a corporate advantage here?
- _djo_ 11y agoBecause the intention is to migrate air traffic control systems to the use of ADS-B data to replace or augment Secondary Surveillance Radar.
- fit2rule 11y agoIf I'm in a plane that is being controlled through a TCAS input, you can be damn sure I'd like anyone on the ground at all to know that I am in that plane. The reason is: planes are a life-threatening situation. You cannot live in a plane. They are a temporary place in which you must park your body during periods of extremely high risk. If two planes crash, because: IT HAPPENS, then not having to decrypt the flight manifest to determine who was on the plane, is a mighty fine use of public force, i.e. law-making. I care not a fig for someones' privacy, if it means life-saving activities have one less layer of human cruft attached to the process. If you're coming to find my body on the side of the mountain because I was unfortunate enough to hitch a ride with my rich millionaire and his drunk pilot, please know exactly who I am, and how to contact my immediate family, in case of my demise.
- dagw 11y agoI guess we'll have to agree to disagree. I feel very strongly that if one wishes to get away for awhile and not tell the world where you are heading then you should very much be allowed to do that.
- VLM 11y agoIts exactly analogous to refusing to ring your fog bell on a boat while stuck in a fog bank, or refusing to use turn signals on a car.
- dagw 11y agoIt's not at all analogous. A turn signal tells the people around me that I'm just about to turn, not that I'm on a road trip from Chicago to Tucson. Nor is my entire turn signal history centrally logged and searchable.
- jMyles 11y agoThere are two analogies: - The broadcast of your location data is analogous to a turn signal. - The FR24 community is analogous to a group capturing data about use of turn signals at various intersections and aggregating them. Both are perfectly reasonable analogies. And yes, it's completely possible for people using only publicly-visible information to put together your entire turn signal history and make it searchable.
