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.
