Abstract: The invention provides systems and methods adaptable to all gaseous agents including Helium to suppress fire in at least one enclosed space. Suppressants are delivered by a dedicated subsystem connected to cargo compartments or to engine nacelles, or by an integrated system connected to cargo compartments and engine nacelles. For example, at least a first reservoir stores fire suppressant composition for knocking down a fire in an enclosed space. Piping delivers the composition from the at least first reservoir to the enclosed space. A pressure sensor senses pressure of the composition in the piping, and a controllable purging device permits air to exit the enclosed space responsive to sensed pressure in the piping of the composition.

Abstract: A system for automatically correcting flight path of an aircraft onto a predetermined trajectory is provided. A sensor is configured to sense speed and direction of air relative to the aircraft at a predetermined distance in front of the aircraft. A navigation system is configured to determine displacement of a flight path of the aircraft from a predetermined trajectory. A processor is coupled to receive the sensed speed and direction of air from the sensor and the displacement of the flight path from the navigation system. The processor includes a first component that is configured to determine whether the speed of the air at the predetermined distance is indicative of turbulence, and a second component that is configured to automatically generate control signals to correct the flight path of the aircraft from the displacement onto the predetermined trajectory by a time when the aircraft enters the turbulence.

Abstract: A stowable module, i.e., a storage container, that provides storage space in the airplane without occupying revenue floorspace. The stowable module comprises an integrated feature of a sidewall lavatory. The stowable module stows inside a sidewall lavatory during ground, takeoff, and landing operations. During flight, the stowable module is deployed by a flight attendant into an adjacent doorway area so that the lavatory can be used by passengers and crew.

Abstract: An aircraft locking system (11) is provided that avoids inadvertent or deliberate operation of an aircraft exit opening means (50) during take-off roll, in-flight, or during landing. The aircraft locking system includes means for determining whether engines of the aircraft are running (12), means for determining thrust lever position (14), means for determining whether the aircraft is in an air mode or a ground mode (16), and means for determining whether a predetermined number of service/entry doors are closed (18). Means for generating a lock/unlock signal (32, 40) are responsive to the engine running determining means, the thrust lever position determining means, and the service/entry door-closed determining means.
