Testing your glide. Are people doing this?

("Yossarian" wrote in the Catalina Perep thread)
My first trip I was that low too, but now my FBO insists on a continuous
climb to the middle of the channel for better glide distance if your
engine
quits. 4500' in a 172 is only like 7 miles glide.


I wonder how many people have actually glided their planes (rentals or
otherwise) and so know what their real world glide range numbers will be -
from say, 6,000 ft AGL down to 3,000 ft AGL? Into the wind vs tailwind, etc?

I'm under the impression that 5:1 is a good (safety) number to have in your
head for an average 172 flying at 3,000 ft AGL, and below. Gives you some
"what the hey?" room and *some* turning room.

Can't quite make a 3 mile target with exactly 5:1 at 3,000 ft AGL....15,000
ft. Leaves you 840 ft short of 3 miles. Still, (a mile glide per 1,000 ft of
altitude) seems like a good number to keep in your head for lower altitudes.
Almost 5:1.

I wonder how much better (than the made up safety number 5:1) people will
see up at 6,000 ft AGL. Are people getting book numbers, in their planes,
when they go up and practice real world glides - from say 6k down to 3k?
