With the throttle at idle, and plane trimmed for best glide, what is
your plane's descent rate (in fpm)?

I tried this with my Cherokee 180 and found the resulting descent to
be somewhere between 900 and 1000fpm. (This was measured on the VSI,
not via altimeter plus stopwatch, so it is prone to error).

Varying the glide airspeed 5 or 10 mile an hour did not make a big
change in the descent rat, probably 50fpm or so.

Anyone tried the same?

I got about the same results with a 172.
