You don't know where the engine will stop... for many reasons. You must estimate your altitude, gliding efficiency, landing point, and where you will land. I'm always training for an emergency landing, if it happens, from different altitudes over the airport.
- Hi Dave, thanks! You mean this black thing on the top of wing? This is new safety system Phantom 450, who is activated without a rocket. Its efficiency is very similar as rocket systems. Max weight 450kg/speed of flight 150km/h. Its certificated DULV/DAeC
