REFLECTOR: Gear warning horn

What might be your intentions? If I stretch /a lot/, I can come up with 
a couple of scenarios - none of which I would regard as really 
necessary, and most certainly of very limited duration. I would view the 
horn as a tolerable bother for a couple of minutes, or (more logically) 
just add enough power to turn it off during the descent. If I'm making 
such an unusually expeditious descent, I'm clearly way behind the 
airplane which is precisely the purpose of the horn. Throttle position 
switch (that is already there) is more reliable and less complex than an 
airspeed switch and I already have more failure modes than I really need.

Are we PVORT again? .... Jim S.

PS What might be the purpose of "an airspeed switch go prevent gear up 
while on the ground"?
... inquiring minds need to know ....
