Reading from the above it would seem that the alarm system is totally
inactive until the GPS indicates I am moving 25+ knots.

I believe the 302 uses airspeed, not GPS ground speed, to do the
measurement.

If so, how
can I test this system on the ground? Anyone else install this system
and have any experience? This weekend I will experiment to see if
the 302 programming is smart enough to allow testing while I am
standing still.

Thanks, John DeRosa

Launch, release from tow, open spoilers with gear up, listen for
warning horn.

That only tests the gear warning, which can also be done on the ground
with the fuselage in the trailer dolly and the gear up.

To test the "spoilers unlocked" warning, the airspeed must increase past
25 knots while the spoilers are unlocked, and once you have released
from tow, the airspeed won't do that.
