GE SR-22 Flight Simulator Demo: Testing Static Stability
Google Earth SR-22 flight simulator demonstration: Testing the static or longitudinal stability. This is the ability of the aicraft to return to the original trimmed attitude after a disturbance in pitch.
For a vehicle to possess positive static stability it is not necessary for its speed and orientation to return to exactly the speed and orientation that existed before the minor change that caused the upset. It is sufficient that the speed and orientation do not continue to diverge but undergo at least a small change back towards the original speed and orientation. This is what we see in the simulation.
