摘要： A shimmy damper for centering a landing gear includes a cap and a housing. The shimmy damper further includes a damper shaft extending from the cap to the housing. The shimmy damper further includes a plurality of magnets configured to exert an opposing force on the cap and the housing via the damper shaft, providing a centering mechanism of the damper shaft within the housing. This centering action in turn provides for the centering of the landing gear during flight.

摘要： An aircraft landing gear assembly is disclosed including a landing gear bracket, a fore lever receiving a fore aircraft wheel, an aft lever receiving a rear aircraft wheel, the fore and aft levers being independently moveable, wherein the bracket further comprises a fore lever stop to prevent downwards movement of the fore lever past a lowest rotational position with respect to the bracket at a first angle α1 forward from the notional bracket axis, and a rear lever stop to prevent downwards movement of the rear lever past a lowest rotational position at a second angle α2 behind from the notional bracket axis, wherein the first angle is greater than the second angle. An aircraft and a method of landing an aircraft are also disclosed.

摘要： A system and method for display of judgmental oversteering taxi data receives a plurality of parameters from aircraft, environmental, position and path sources and determines and displays accurate oversteering data to a pilot. The system enables the pilot to make a variety of taxi turns confident that all aircraft wheels remain on a prepared surface. Aircraft sources include data associated with the aircraft including whether the aircraft has steerable body gear. The environmental parameters include weather, surface friction, and additional data applicable to a turning radius of an aircraft. Position data includes GNSS data to accurately position the aircraft aligned with the taxiways. Path data includes an assigned ATC clearance as well as taxiway data associated with the assigned taxi route. The method compares each of these received variables with stored database information to ensure the aircraft maintains a safe position on the prepared surface during a turn.
