Claim 0:
1. A landing gear system for an aircraft comprising:
a nose gear disposed proximate a front of the aircraft, the nose gear comprising:
a main strut/gear link;
a rotatable aft/retract link rotatably attached to the main strut/gear link;
a pivot-piston rotatably attached to the aft/retract link;

the nose gear controllably movable between a first position, in which the nose gear is extended, and a second position, in which the nose gear is retracted; and
a main gear, coupled to the nose gear, the main gear disposed proximate a rear of the aircraft, the main gear controllably movable between a third position, in which the main gear is extended, and a fourth position, in which the main gear is retracted;
wherein, in a ground position, the nose gear is in the second position and the main gear is in the third position and a fuselage of the aircraft is substantially level with the ground; and
wherein, in a pitch angle position, the nose gear is in the first position, and the main gear is in the fourth position and the fuselage of the aircraft is rotated to a positive pitch angle with respect to the ground;

a valve coupled to a main cylinder and the pivot-piston, the valve comprising a closed position and an open position;
wherein, in the closed position, the valve prevents a flow of a fluid between the pivot-piston and the main cylinder;
wherein, in the open position, the valve enables the flow of the fluid between the pivot-piston and the main cylinder.
