In my S35 the gear horn start at about 13-14 inches. Bottom of the
green is 15 inches. I reduce to 15 inches about 5 miles out. My gear
speed is 165 but I like to be around 145 or less to save wear and tear.
After putting some time on my Bo this last 11 months I am convinced
that many gear ups happen because pilots don't slow down enough in the
pattern. I have a hard time getting below 100 without putting the gear
down. I know Bonanza pilots who are deathly afraid to ever get below
100 unless their wheels are inches from the ground.

With regards to my Bonanza, this horn is practically useless as it will
only sound when manifold pressure drops below 12 inches, well below the
green arc on the MP gauge (implying that for the majority of the approach
the horn would be silent).

It is not until power is pulled almost all the way back, which in my case
typically is less than 50 feet above the runway or about a second before
touchdown.
