Wheel-barrowing

Wheel-barrowing is a problem that may occur when an aircraft pilot places excessive forward pressure on the elevator control of a nose-wheel equipped aeroplane during the takeoff or landing phase of flight. Forward pressure on the flight controls places an up force on the horizontal tail, thereby transferring weight from the landing gear main wheels to the nose wheel. The aircraft, in effect, behaves like a wheelbarrow and directional control is compromised. In extreme cases, the propeller of a single engine airplane may strike the ground damaging it and the engine, or the aircraft may tip over on the nose-wheel and one main wheel causing wing damage.
