Pilot Mike,
Thank you. I have the theory, what I need are actual operating speeds from a Cessna expert. Our poster has now brought up a Cessna graph for the 172 that gives 60kt as Vmp, 75kt as Vmd and 95 - 105kt for cruise. This would make gliding for best angle 75kt, and gliding for endurance 60kt. Is this what you actually do? And what climb speed do you use?
