"jitter" when the aircraft was stopped.  This is a fundamental
characteristic of the gear model, and can't be fixed without major
surgery (and not a small amount of blinding insight).  But we can at
least clamp it so the value can't change unless the wheel is moving
with a nontrivial velocity (5cm/sec in this case).
