Glide Ratio
I am just curious what other aircraft out there get as far as glide ratio's are concerned. I know some high performance gliders are capable of glide ratio's on the order of 36:1, or so I've read, I have no glider experience. The PC12 I fly travels 2.6 miles for every 1,000 feet lost in its glide. That seems to work out to a glide ratio of 13.728:1. I don't have any POH's other than for the Pilatus on hand and I'm curious what other aircraft out there get for an (all)engine(s) out glide ratio.

1966 Mooney M20E 1.9 nm per 1000' = 11.552:1
1977-1979 Grumman Cheetah 1.7 nm per 1000' = 10.336:1
1980 Cessna 172N 1.5 nm per 1000' = 9.12:1
(1.4nm with floats = 8.512:1)
Math is hard

Ok, I just realized that I was converting feet to miles by a factor of 5,280 instead of 6,076. By those (the correct numbers), the PC12 is over 15:1, not quite 16:1 in its glide ratio. Sorry, that was pretty stupid. I was forgetting the difference between nautical and statute miles.
