Computerized system and method of controlling a refueling device including, when the device is in a non-engaged state: receiving a first roll angle of a tanker, determining a first desired roll angle, and providing a command for controlling a roll element, thereby attempting to achieve or maintain a first roll angle that is substantially the same as the roll angle of the tanker. And, when the device is in an engaged state: receiving a second roll angle of the tanker, determining a second desired roll angle, and providing a command related to the desired roll angle for controlling a yaw element, thereby attempting to achieve or maintain a second roll angle that is substantially the same as the roll angle of the tanker, wherein the roll angle of the device during the engaged state is facilitated due to a degree of freedom between the refueling device body and refueling nozzle.

A self-adjusting flight control system is disclosed. In various embodiments, an input interface receives an input signal generated by an inceptor based at least in part on a position of an input device comprising the inceptor. A processor coupled to the input interface determines dynamically a mapping to be used to map input signals received from the inceptor to corresponding output signals associated with flight control and uses the determined mapping to map the input signal to a corresponding output signal. The processor determines the mapping at least in part by computing a running average of the output signal over an averaging period and adjusting the mapping at least in part to associate a neutral position of the input device comprising the inceptor with a corresponding output level that is determined at least in part by the computed running average.

A coupling comprising a brake plate (70); a first friction pad (64) operable to be selectively biased against the brake plate (70). In a first mode of operation the first friction pad (64) is biased against the brake plate (70) by a first force. In a second mode of operation the first friction pad (64) is biased against the brake plate (70) by a second force. The second force is substantially greater than the first force.

A system and method of controlling one or more flaps of an aircraft may include receiving first and second sensor signals from respective first and second sensors coupled to respective first and second actuators that are moveably secured to a first flap of a first wing of the aircraft.
