I'm kind of embarrassed I don't know this:
. Everyother airplane I ever flew, they gave you the best glide ratio and what speed to obtain it in the event of an engine failure. So I set out to figure it out myself in my 8. I always thought 1 nautical mile was 6000'. Turns ot it's actually 6076.115 feet.![Eek! :eek: :eek:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Anyway there are you guys out there who are way smarter than me. I've got XM Sat Wx on my GPS and it shows the winds. So I went out experimenting, today, by trying out simulated engine failures flying 90* to the winds ( no headwind or tailwind), throttle closed, and CS prop full decrease RPM. ( A glide ratio of say 9:1 means for every 9000' you go forward, you lose 1000' in altitude, right?--( Told you I was dumb). Lets forget the 6076. 115 Ft--let's just say 1 NM = 6000'. So if I go 2 NM or 12000' horizintally, and lose 1000' in the process, that's a 12:1 glide ratio,right??![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
If my thinking on how this works is correct, I found the recommended 71KIAS glide speed is a recipe for disaster. About 84 KIAS seems to give the best results--BUT-- of course the slowest speed possible at the bottom is life saving. ( I know--speed depends on weight 1518 Lbs. fully loaded for me-- but I'm just looking for some education)
