201. We lose an airplane for 2 really simple, stupid reasons

Tue Mar 11, 2014, 01:36 PM

Mar 2014

1) We build planes in a way that allows the pilot to turn off the transponder. That makes no sense. That thing should be on as long as the plane is in the air, not just for these cases, but for everyday safety concerns. It is stupid to allow a design where a pilot (or hijacker) can turn it off.

2) We have an air-to-ground communication network for passing all sorts of information that helps the airline run the day-to-day business. We should be mandating that the essential aircraft status information (in a distilled form that won't overload that network) be automatically transmitted in real time as long as the aircraft is in the air. Some airlines use this capability, but there is no indication that was an available source in this case.

If we had these two things, we would have known what was happened BEFORE the plane crashed (assuming that it crashed.)
