1. An aircraft comprising:
a pressurization vent door that is moveable between a pressurization position to close a depressurization vent to allow the aircraft to be pressurized, and a depressurization position to open the depressurization vent to depressurize the aircraft;
a locking vent door that when moved to be open in an opening position opens a lockout vent, and when moved to be closed in a closing position closes the lockout vent, wherein the locking vent door is prevented from being moved from the closing position when a pressure difference between an interior air pressure and an exterior air pressure meets a threshold; and
a handle that controls the pressurization vent door and is moveable to an engaged position to control the pressurization vent door to be in the pressurization position, and a disengaged position to control the pressurization vent door to be in the depressurization position, the handle being releasably connected with the locking vent door,
wherein the handle is releasably connected with the locking vent door so that:
when the locking vent door is in the closing position, the handle is secured in the engaged position so that the handle is prevented from moving into the disengaged position, and
when the locking vent door is in the opening position, the handle is moveable to the disengaged position to permit the pressurization vent door to be in the depressurization position.
