I would like to know what the GPS speed is doing there in the 1st place. It does not tell you a darn thing about the aircraft as far a flying goes. The aircraft does not fly on GPS speed, nor does it fly on TAS (Unless you are talking MMO) BUT it does fly on IAS (or CAS if you are a purist) However a good AOA gauge should tell you everything you need to know, IF you knew a little about aerodynamics and knew how to read the gauge. (And pull yourself away from the FMS and actually fly the thing)
