GPS position reporting system
One question from an electronics engineer. I understand that most problematic element in any security enhancement, or indeed any change in aircraft design, is mostly centered on extensive testing that is required on one hand, and the need for it to be integrated in an already extremely complex system. However, if we add system that is very small, autonomous, and only physically attached to some external part of the aircraft, than the cost and time necessary for its introduction would not be so big.
It would be very easy to add external device with internal GPS that can send aircraft position every 5 minutes or so over its own satellite uplink. It would need only power from the plane, nothing else. No attachment to any other aircraft system. No plane would be lost ever again, anywhere. Rescue effort can begin immediately, even at the first hint of a problem. Some lives would be saved and psychological problems of relatives and possible survivors would be much easier. No survivor can feel that he is lost or abandoned for the moment. It’s that easy. Technical problems are insignificant, cost of the unit also. No significant change to aircraft needed. It is not necessary to calibrate it, control, or maintain. It is simply kind of external, autonomous satellite mobile phone with included GPS attached to whatever part of the plane is most easily adapted for that purpose.
Is it possible to implement something like that?
