ABSTRACT:
An aircraft waste storage system and method intended to avoid leakage of liquid waste from an aircraft waste holding tank through the tank outlet tube during flight. The system uses a valve movable from a position at a predetermined depth within the outlet tube to form a liquid-tight circumferential seal with the outlet tube interior surface during flight to an open position during ground servicing in which the valve is withdrawn into the tank to allow the waste to discharge. The waste system uses an electric motor and drive screw to move the valve, which is controlled from the aircraft. It incorporates an alarm to provide a warning if the valve has failed to reach the predetermined depth within the outlet relied upon to prevent leakage.
