Abstract: A boresighting mechanism for adjusting an armament of an aircraft. The mechanism includes a housing comprising a proximal end, a distal end, and an inner cavity. The mechanism further includes a jackscrew with a threaded portion disposed in the inner cavity and an unthreaded portion extending from the proximal end of the housing. The mechanism further includes a follower threadedly coupled to the jackscrew at a first end within the inner cavity and extending from the distal end of the housing. The follower is configured to be coupled to an adjustment feature of the armament at a second end. The mechanism further includes an adjustment knob coupled to the unthreaded portion of the jackscrew and configured to rotate the jackscrew to thereby cause linear motion of the follower. The linear motion allows for adjustment of the armament via the adjustment feature.

Abstract: A harness includes a primary locking mechanism, at least one strap of webbing coupled to a primary locking mechanism, and a secondary locking mechanism associated with the at least one strap of webbing. The secondary locking mechanism is located downstream from the primary locking mechanism and is movable to selectively contact the at least one strap of webbing to restrict movement of the at least one strap of webbing relative to the secondary locking mechanism.
