You only have to transmit data when something is wrong. You can use software to determine when to start sending updates.

- marcusbooster 17y agoYou have to re-construct the flight before things go wrong to know when things went wrong. Maybe something you thought was right turned out to be an error given a different parameter. Kinda like debugging I guess.
- shiro 17y agoThere certainly are cases with well-understood causes (e.g. birds flew into both engines to make them stop), but I guess there are cases that originally caused from combination of previously-unknown failure pattern; since the failure pattern understood enough to write a software to detect, it may likely be backed up by some fail-safe mechanism. I don't know much about aircraft controlling software, so this is only a guess from my experience of general system software crash recovery; usually the hardest case is caused by something I've never imagined to happen.

- JimmyL 17y agoWhen a plane is flying and not transmitting anything, is the reason that nothing's wrong, or that the system that sends updates when something goes wrong (possibly among others) is broken?
- HeyLaughingBoy 17y agoNo. Part of failure analysis is understanding what led to the failure in the first place. If you only transmit when something goes wrong, you may end up knowing what went wrong, but not why And why is usually just as important.
