Abstract
There is provided a latch indication system for a fan cowl of an air vehicle. The system has a door movable between a closed position and an open position, and has a handle movable between a handle stowed position and a handle deployed position. The system has a linkage assembly mechanically connecting the handle to a cover assembly. The cover assembly has a movable member movable between a movable member stowed position and a movable member deployed position, such that when the door is in the closed position and the handle is in the handle stowed position, the system indicates that one or more latch assemblies of the fan cowl are in a latched condition, and when the door is in the open position and the handle is in the handle deployed position, the system indicates that one or more of the latch assemblies are in an unlatched condition.
