A. Description
The Landing Gear (L/G) system has: - two Main Landing Gears (MLG) and their related doors (Ref. 32-10-00) - a Nose Landing Gear (NLG) and its related doors (Ref. 32-20-00) - two extension and retraction systems for the L/G and their related doors (Ref. 32-30-00) - L/G wheels and their related braking systems (Ref. 32-40-00) - a NLG steering system (Ref. 32-51-00) - a L/G indication and warning system (Ref. 32-60-00).
The L/G support the aircraft on the ground and are oleo-pneumatic shock absorbers that absorb taxi and landing loads. During flight the L/G is retracted into the landing gear bays in the belly of the aircraft. When the L/G is extended or retracted the related doors close to make the aerodynamic contours of the aircraft.
