212man,
I raised a number of issues....and certainly not all of the possibilities. Any idea why they raised the autopilot training issue?
In the foggy recesses of my alcohol ravaged brain, I seem to recall the 76 uses a combinaton airspeed and RadAlt height to trigger the gear warning.
It seems that if you had a strong headwind and some forward speed the horn would not go off which makes me think it requires both inputs to trigger the warning. Someone more current on the 76 can tell us how that works.
Of course at cruise speed....it would not be the horn that woke you up when you hit the water.
