GPS software and aircraft displays
With the latest software that is now available in stand alone GPS devices.
It might be an idea if a separate GPS system with its own power supply was provided to give the crews a better spatial monitoring system.
It would allow the crew to view a 3D perspective of where the aircraft is in relation to the ground below and whats ahead.
Imagine a flight sim screen but showing the aircraft in profile against the surface of the earth which is monitoring the position and altitude in real time.
Just a thought if any makers are reading,
