I personally train myself once a quarter on the following procedure to check if I can make an airport landing when engine is off:
When an airfield is in the Skydemon gliding range (software widely use un Europe), I stop the engine, and see how I manage to land safely on the targeted airfield
Glide ratio needs to be set in Skydemon: It turns out that 9:1 is the right setting for a CTSW
This helps me in my emergency procedure if engine die:
- Check if any airfield are in the blue circle: if yes, fly straight there with flaps at 0° and speed at 63 knots. If not, then I target a field.
