SYSTEM FOR LATCHING AND LOCKING AN AIRCRAFT DOOR

Abstract:

Systems for latching and locking an aircraft door and associated methods are disclosed. The system comprises a latch and a lock. The latch can be configurable between: a latched configuration where the latch interferes with a lift mechanism for causing lifting of the aircraft door to permit opening of the aircraft door; and an unlatched configuration where the lift mechanism is permitted to cause lifting of the aircraft door. The lock can be configurable between: a locked configuration where a configuration change of the latch from the latched configuration to the unlatched configuration is prevented; and an unlocked configuration where the configuration change of the latch from the latched configuration to the unlatched configuration is permitted.
