I have practiced engine out glide with my full feather three blade Hartzell prop (Model number HC-H3YF-2UF) in the full feather position and fully stopped. My Lancair glides at 120 KIAS with 550 fpm descent at moderately loaded weight. This translates to 21.8 to 1 glide ratio. It glides unbelieveably well, with plenty of time to calm oneself as you prepare for an engine out approach, programmed into the Chelton as mentioned previously.
I can now simulate this engine out glide with a flat pitch 2500RPM prop setting and 10.5" MAP, which is just a wee bit less than the power setting on a normal final approach.

Hello guys
For what I have gathered so far the lancair 4p has a glide ratio similar like a piano LOL In other words if the engine quits then open the door, throw out your keys because there is where you land LOL
Well, this might not be true, or is it?
So how about the full feathering prop ? Does anyone have experience with the before and after installation? How much they cost and data?
Thanks -- Ronald
