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.

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.

A safety open and closing system for an overpressure door on fuselage of an aircraft. Wherein the safety opening and closing system allows safe access through the overpressure door to the compartment. The safety open and closing system including an assembly of a hollow beam, a blocking bar in the hollow beam, a spring biasing the blocking bar with respect to the hollow beam and a lever at the end of the blocking beam which pivots between a position A that allows closure of the overpressure door and a position B preventing closure of the door.

A door latch assembly configured to be used in an aircraft lavatory door. The door latch assembly includes a housing that includes a housing interior, a switch member operatively associated with the housing that is rotatable between a first position and a second position, and a locking bolt that is movable linearly between an unlocked position and a locked position. Rotation of the switch member from the first position to the second position moves the locking bolt from the unlocked position to the locked position.

A monument arrangement for a cabin of a vehicle has a first monument, with a washroom formed therein, a second monument and an aisle. The first and second monuments enclose the aisle, wherein an access opening to the washroom is directed toward a side wall of the second monument and is adjacent to the aisle. The distance between the access opening and the relevant side wall of the second monument is at most 1 m, and the side wall of the second monument has a first, rigid side wall portion and at least one second side-wall portion, which is mounted on the first side wall portion such that it can be pivoted about a vertical axis and which can be pivoted from a neutral position, running in the direction toward the first side wall portion, into an angled position, directed away from the first monument and the aisle.

Cradle assemblies for supporting a door of an aircraft to facilitate servicing the door, and arrangements and methods for the same are provided. In one example, a cradle assembly includes a base and a cradle support subassembly pivotably coupled to the base. The cradle support subassembly is configured to support an outer section of the door.

The handle attachment includes a base portion that can be attached to a portion of a wall surface of a door, a flap portion that applies, as a result of a pulling operation, a pulling force to the door via the base portion, a flap rotation mechanism that rotatably connects the flap portion with respect to the base portion around a rotation axis, and a biasing member that biases the flap portion in a first rotation direction around the rotation axis with respect to the base portion. The flap portion includes a base end portion connected to the flap rotation mechanism and a distal end portion arranged at a position away from the flap rotation mechanism. The first rotation direction is a direction in which the distal end portion of the flap portion separates from the wall surface of the door.

An aircraft door, and, more particularly, to an electromechanical door system for operating an aircraft door that closes an opening in the outer hull of an aircraft, as well as to a method of operating an electromechanical door system of an aircraft door that closes an opening in the outer hull of an aircraft. The electromechanical door system may be adapted for operating in a normal opening mode, an emergency opening mode, and a closing mode. If desired, the electromechanical door system may include a lifting and lowering lever, a lifting and lowering electric motor, and a gearbox that transmits a force from the lifting and lowering electric motor to the lifting and lowering lever.

Door assemblies, aircraft including door assemblies, and method for making door assemblies are provided. In one example, a door assembly includes a hinge subassembly and a door pivotally coupled to the hinge subassembly. The door has a channel disposed therein with a holding member disposed proximate a channel distal portion. A sliding member is movably disposed in the channel. An arm has a first portion pivotally coupled to a second hinge subassembly and a second portion pivotally coupled to the sliding member to move the sliding member as the door moves between a closed position and an open position. A stay member is coupled to the sliding member to move towards the holding member which holds the stay member in position when the door is moved to the open position to hold the door open.

A monitoring system and method are configured to detect a status of a door for a component on a vehicle. The monitoring system includes a sound sensor positioned within an auditory range of the door. The sound sensor detects sound energy generated in relation to a closed position of the door and an open position of the door. The sound sensor outputs a sound signal indicative of the sound energy. A monitoring control unit is in communication with the sound sensor. The monitoring control unit receives the sound signal and analyzes the sound signal to determine the status of the door.
