    Abstract: Air vehicles, fly-by wire systems, and method for preemptive mitigation of turbulence are provided. An air vehicle includes a flight control surface, a sensor, and a controller. The sensor is configured to determine a velocity of an air mass that is separated from the air vehicle by a predetermined distance. The controller is communicatively coupled with the sensor and is configured to determine whether the air mass will disturb smooth flight of the air vehicle. The controller is further configured to manipulate the flight control surface in response to determining that the air mass will disturb smooth flight of the air vehicle.

    Abstract: An auxiliary power unit inlet assembly includes an inlet duct having a first end and a second end. The auxiliary power unit inlet assembly further includes a door associated with the second end of the inlet duct. The door moves between a first position and a second position. The door closes the second end of the inlet duct when in the first position and permits air to enter the second end of the inlet duct when in the second position. The auxiliary power unit inlet assembly further includes a sound absorbing component mounted to the door and disposed proximate the inlet duct. The sound absorbing component is positioned at a location on the door such that a noise generated by the auxiliary power unit will directly impinge on the sound absorbing component.

    Abstract: A tunable stay device for an aircraft closure has a mounting base that is mountable to the closure or in an area of the aircraft in close proximity to the closure. The mounting base extends, at least in part, along a mounting axis. A holding element is mounted for movement along the mounting axis and configured to effect, at least in part, a hold force. An adjuster is mounted to at least one of the mounting base and the holding element and is configured and arranged to effect a change in position of the holding element with respect to the mounting base along the mounting axis. When the stay device is mounted to the closure or in the area of the aircraft in proximity to the closure, the hold force biases the closure in one of an open orientation and a closed orientation.

    Abstract: Air stair support systems, stair support cable assemblies, and hooks are disclosed herein. A stair support system includes, but is not limited to, an aircraft fuselage, a door seal, a stair door, and a stair support cable assembly. The aircraft fuselage defines a door frame and a stair hook receptacle. The stair door has a retracted position within the door frame and an extended position that forms an entry/exit stairway. The stair support cable assembly includes a cable and two hooks. The first hook includes a curved end portion configured to hook onto the stair hook receptacle, a cable end portion secured to the cable, and an intermediate portion having first and second intermediate legs that extend the intermediate portion away from the door seal when installed on the door frame and the stair door. The second hook is configured to hook on the stair door.
