Abstract: An aircraft control system includes: a motor with a rotating shaft; a pilot control input; a linear actuator connecting the pilot control input to the rotating shaft; a sensor identifying a position of the pilot control input; and a transmitter transmitting the pilot control input position to a controller, the controller adjusting an aircraft performance device based on the received pilot control input position.

Abstract: In one embodiment, an aircraft display system includes a first module that identifies a label in an ARINC 429 communication between a flight director and a display, a second module that removes flight director data from the ARINC 429 communication, the flight director data associated with the label, and a third module that inserts substitute data in the ARINC 429 communication. The display receives the substitute data before an error is detected.

Abstract: An aircraft safety system includes a Stall/Spin Warning & Recovery Computer, an angle of attack sensor, a side slip sensor and an angle of attack display. The Stall/Spin Warning and Recovery Computer detects whether the aircraft is in a safe condition or an unsafe condition. The angle of attack display includes a first configuration that displays information indicative of safe aircraft condition when the orientation detector detects a safe condition and a second configuration that displays information indicative of unsafe aircraft condition when the computer detects an unsafe condition. The display may transition from the first configuration to the second configuration when the orientation detector detects an unsafe condition and then to a third configuration, which may include visual control-input instructions that enable recovery to a safe condition.

Abstract: A power line warning system for a helicopter, comprising a positioning system operable to determine the coordinates of the helicopter, an obstacle coordinate database comprising the coordinates of at least a portion of a first power line, a sensor operable to detect electromagnetic radiation from the first power line, and a visual display operable to represent a position of the first power line relative to the helicopter is described. When the coordinates of the first power line are within a predetermined distance of the coordinates of the helicopter, wherein the representation of the position of the first power line is modified when the sensor detects electromagnetic radiation from the first power line.
