Automatic 7700 selection
Just curious.
Given the advancement of onboard FMS systems, would it not be possible to create a system whereby certain flight conditions would automatically cause the selection of 7700 on the transponder?
Understandably, the first task of the crew is to fly the aircraft, so if a way could be found to automatically alert ATC to an emergency descent which possibly also includes a turn off track - in a busy traffic environment, that cannot be a bad thing?
