Abstract: The disclosed embodiments relate to an aircraft having an in-flight leveling system for a seat onboard the aircraft that includes a swivel mechanism providing selective rotational movement of the a rear portion of the seat to compensate for an angle of inclination of the aircraft during flight. A locking mechanism is coupled to the swivel mechanism to retain the seat in a first position for use on the ground and a second position for use during flight. An actuator moves the locking mechanism between a locked condition and an unlocked condition permitting the seat to move between the first position to the second position enabling the seat to be substantially level when the aircraft is on the ground and during flight.

Abstract: An adjustable depth control mechanism for use with earth penetrating equipment. The invention includes a hub and spindle assembly for use with an adjustable depth gauge wheel, which is mounted on a support axle. It may also include a position indicator that an operator can readily view to determine the relative position of the depth gauge wheel and, accordingly, the depth setting of the ground penetrating disc. The indicator rotates to certain positions that correspond to the depth to which the disc is allowed to penetrate into the ground. Preferably, both the position indicator and the adjustment mechanism of the assembly are located internal to the depth gauge wheel and are covered and protected by the rim of the wheel from contamination by soil and crop residue.
