Yes the temp. Would cause everyone to pass out . that's why they ask you to keep the mask on if that happens so you wont pass out. I have a question if the auto pilot was engaged and the plane is flying itself wouldn't that send data and speed and aircraft where about is . I am so lost how you build a aircraft and tell everyone how you can track it . and how you can turn off tracking devices . but dammm so funny how police cars and other things we have you can track and also have extra security for tracking . I think they should make something that will kick on if the transponder and acars system was to shut down alerting military radar so a team of f16 jets can check the where about are . this can be prevented if we use our BRAINZ
Please review the two links I've given earlier from pilots.
The internet is alive with, "if XYZ can do it, surely an airplane could."
Not true.
If signals were lost because, for example, antenna or transmitter power was lost then switching from Box A to Magical Box B is not going to get the signal out.
If for example, safety circuits turned things off (fire or potential fire) they wouldn't allow Magical Box B to be switched on either.
And because of fires and other scenarios that have already happened, they build airplanes so that pilots can turn off any significant system - and by safety regulations, Magical Box B would probably be included right after it was invented.
Next - autopilot doesn't tell anyone except the pilot what it's doing.
Finally - when the data recorders are recovered, and what happened is known, that will be the time to see what, if anything, can be improved.
Lots of brains have been looking at flight safety, beginning with the flight path that the Wright brothers took for their first flight (no fooling).
You will never be able to completely prevent this sort of problem unless you ground all aircraft. Refer to my earlier post about what happens when you build a better mousetrap or make things more idiot-proof.
Sorry.
PS - fwiw, I've been through and inside every part of a Boeing 707, from the bare metal outside through each and every layer and subsystem leading to the interior as well as a number of other vehicles while working for the USAF. I've not been through a 777. And I am not a pilot.
I'll continue to make every effort to identify where I'm stating opinions.
Very little of what we're facing here involves known facts.
