An aircraft nacelle is disclosed and includes a first fan cowl and a second fan cowl. An opening is defined in an exterior surface of the first fan cowl. The aircraft nacelle also includes a blade, a latch mechanism, an arm, and a linkage assembly operably connecting the arm to the blade. The blade is moveable along between a stowed position and a deployed position. The latch mechanism is moveable between a latched position an unlatched position where a portion of the latch mechanism obstructs a path of movement of the blade. The arm is unable to move from an extended position where a portion of the arm extends through the opening in the exterior surface of the aircraft nacelle into a retracted position within an interior volume of the aircraft nacelle when the blade is in the deployed position and the latch mechanism is in the unlatched position.

Mechanism for indicating position of a latch mechanism for an aircraft nacelle

A latch indication assembly includes a latch and an indicator assembly. The latch is movable between a locked position and an unlocked position, and is configured to secure a fan cowl of an aircraft. The indicator assembly is operably coupled to the latch, and includes an indicator movable between an open position and a closed position responsive to movement of the latch. The indicator extends from an exterior of the fan cowl when in the open position, and is visible from an exterior position proximate at least one of a side or an underside of the aircraft when in the open position. The indicator assembly extends to the open position when the latch is in the unlocked position, and is configured to be retractable to the closed position when the latch is in the locked position.
