Abstract: A flag mechanism for an aircraft door includes a first arm and a second arm each having a flag on a first end and a catch on a second end. A first cam is operatively coupled to a first latching member and a second cam is operatively coupled a second latching member. The first and second latching members are each configured for latching the aircraft door, which are locked when the first and second cams are rotated to a locked position. A first stud extends from a side of the first cam and a second stud extends from a side of the second cam. The first and second studs are each configured to be received by a respective catch of the first and second arms while the first and second cams are rotated, thereby moving each respective flag from a first position to a second position for simultaneous visual inspection.

Abstract: A door stop includes a scissor link member including a pair of links pivotably coupled together at a central pivot point. The scissor link member has a first end pivotally coupled to a door and a second end pivotally coupled to a floor. The pair of links are configured to abut against one another adjacent the central pivot point when the door is fully open to prevent pivoting at the central pivot point for holding the door open. The scissor link member is releasable such that the pair of links pivot about the central pivot point when the scissor link member is released, thereby enabling closing of the door. The pair of links fold into a nested arrangement when the door is fully closed. The pair of links are configured to deform under dynamic loads to protect the surrounding aircraft structure and indicate a need for inspection.

Abstract: A latch positioning mechanism for an aircraft door includes one or more locking members configured to be partially driven into a frame around the door via rotation of a pivot pin. A frame bumper extends outside of the door in a pre-catch position for contacting the frame. A catch bellcrank is operatively coupled to the frame bumper, and a biasing member biases rotation of the catch bellcrank to bias the frame bumper into the pre-catch position. The catch bellcrank is configured to contact a catch cam when the catch bellcrank is biased into the pre-catch position such that the catch cam prevents release of the one or more locking members for locking the door. Upon the frame bumper contacting the frame when the door is closed, the catch cam is released enabling the one or more locking members to be moved into a locked position.
