MacOS and related don't run the airplane. Pilots have an iPad for some checklists and other things where "have you tried turning it off and on again" works as failure prcedure. If a failure, caused by a compiler bug leading to an overflow in a rare flight situation, happens on an airplane system a reboot is not really the option you want to depend on.
- jasonjayr 7y agoIronically, I recall reading about a mid-flight incident where the procedure to bring things back involved turning the entire plane off and on again.

(I.e. somewhere I read that the A380 is a quite good glider, among other reasons since the wings were designed for larger versions; an F-16 however won't really glide) In a critical situation this is impossible, though.
- sandos 7y agoThat will not always work very well, inertial navigation systems often wants to be completely still for a couple of minutes to calibrate themselves. I have heard about just flying with no G-load for a while and getting some basic instruments working. But I dont think you will get full nav functionality back.
- adwww 7y agoI write software for in cockpit ipad apps - they are becoming more and more integral to the workload of pilots, everything from route planning, guidance, checklists, manifests and ordering fuel. There was actually an incident posted on HN a while ago where IIRC an ipad did a software update or similar at a critical moment, and caused complications bad enough to get an incident report published on some aviation agency's website.
