Ground resonance is a hazardous condition during touchdown or at other times when the helicopter is running while sitting on the ground. A series of shocks to the landing gear can pass through to the rotor disk and cause an imbalance in the rotor system. Under extreme conditions, the imbalance causes violent oscillations that quickly build and result in catastrophic damage of the entire airframe. While filming an episode for MacGyver this Gazelle helicopter pilot encountered the first symptoms of ground resonance and managed to recover from this potentially dangerous situation by taking off. During takeoff, the helicopters door opened in flight but the footage was kept and was aired in the episode.
Wayne Mackey won the 2008 Short Takeoff and Landing competition in the experimental category at the “May Day” Fly-In & Air Show in Valdez, Alaska. His plane is a replica of the well known Piper J-3 Cub and he won the experimental category with an incredible takeoff distance of 49 feet, and an equally impressive landing distance of 71 feet. Check out some of his very impressive short takeoffs and landings out in the bush.
It’s a very hot day and this Russian Ilyushin Il-76 Candid is full and ready for a 3000 kilometer trip. As it reaches the holding point, the pilots prepare this monster for a very long takeoff run. And boy, it’s gonna be a really long one… the plane takes off right at the end of the runway barely lifting its weight into the air giving traffic controllers quite a thrill.
