HELICOPTER GROUND RESONANCE : Understanding this dangerous phenomenon.

To be a good helicopter pilot and to avoid accidents, you need to know the hazardous flight conditions well. This is the second video in the series of "Hazardous Helicopter Flight Conditions". We study the Helicopter Ground Resonance.
