Best Glide / Rate of Descent

In article , says...


Did you read Barry Schiff's article on this subject in the May AOPA PILOT?

Bob Gardner



Yep - I was going to mention that when I saw this thread.
The article was a bit smug (he should have just trimmed to 70Kt, and he
would have gotten his Skyhawk without getting in a row with the CFI) but the
content was very good. In my opinion it would have been even better if he
had talked us through his complete approach to his selected landing area,
directly beneath, including his management of speed, when and how he changes
from best rate to best glide for better control etc. I say this because many
of us do these simulations during checkrides, but not much in between. The
last time I had to do it in a 182, I was a bit surprised how rusty I was on
it, and I'm guessing I'm not the only one.

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

Schleicher Ka8-B : 35 knots, approx 150 fpm :-)

(Approximate, because any air current will affect the rate. Indeed, in
some air currents I get to climb. But I'm sure you worked out by now the
Ka-8 is a glider)

Having crashed both, I can definitively state that a C-210 sinks at roughly 700
fpm cleaned up and a Piper Lance comes down at 1100 fpm in the same situation.
While the extra cabin space is nice, the Cherokees are definitely lead sleds
when it comes to power off descents.


My Beech 23 is easily out glided with the power off by a comparable
PA-28, so that must make the Beech a super lead sled. G

The short winged Cherokee and Musketeers don't glide as well
as the newer -151 Piper versions.
