What is best glide speed? • Speed to fly for greatest distance • Speed to fly for greatest time • They’re the same thing – The longer you fly the further you go. • It depends Federal Aviation Administration 4

Distance • Maximum range speed – – Greatest distance covered for altitude lost Often referred to as best glide speed Roughly half way between Vx & Vy Speed Increases with weight Aircraft Vx Best Glide Vy C 172 53 65 73 AA 5 A 78 83 91 PA 28 161 63 73 79 Federal Aviation Administration 5

Time • Minimum sink speed – Lowest rate of descent – Slightly slower than maximum range speed – Rarely cited in POH Federal Aviation Administration 6

What about my airplane? • Experiment with your CFI – Best glide speed and attitude. Note sink rate. – Minimum sink speed and attitude. Note sink rate. – Power off approaches and landings Federal Aviation Administration 7

Forced landing tips & tricks • Know how far you can glide 1. 5 NM per 1, 000 Ft. AGL Federal Aviation Administration 8

Forced landing tips & tricks • Frequent practice – At typical mission weights • Flaps up approach to between 1 st & 2 nd third of runway or landing area. Federal Aviation Administration 9

Forced landing tips & tricks • Frequent practice – At typical mission weights • Flaps up approach to between 1 st & 2 nd third of runway or landing area. – Add flaps and/or slip to move aim point closer to approach end of the runway – Better to land long & leave runway at slower speed than to stall or land short of the runway.
