GPS can tell you ground speed but not air speed. The latter is the crucial informatiom the pilot needs.

They are different but by how much? Could not ground speed be used as an approximation in an emergency situation? Put the airplane level, put engines on a reasonable power and get to a place where you are not forced to act second by second. When the airplane is level and has a reasonable ground speed should that not preclude stall?

How do you propose to get the plane level without knowing the airspeed, pitch, and/or angle of attack? If the pilots or computers had this information, then they would not need the GPS system you describe.

You are describing a navigation system, not a flight computer or an emergency recovery system.

They can be different by a lot - easily more than 100mph in some conditions.
