WHAT IS A GYROCOPTER?

A Gyrocopter is an aircraft that shares common features with airplanes and helicopters. Like a helicopter, it uses a rotor that develops lift, however, unlike helicopters the rotor is unpowered and it turns in autorotation to provide this lift. It also uses an engine-powered propeller, similar to that of a fixed-wing aircraft to provide thrust. 

This means that if the engine stops is not a dangerous event, but something that is usually caused by the pilot, as the engine must always be stopped for landing. The lift provided by the rotor in autorotation ensures a smooth and perfect landing.
