  • Patent number: 5614897
    Abstract: An aircraft flight instrument display panel (10) has a combined speed and heading indicator in the form of a central square (11) surrounded by a scaled matrix (12). Displacement of an aircraft (100), in which the display is installed, from a desired speed and heading being indicated by displacement of an aircraft symbol (14) in the y and x directions from the central square. The aircraft (100) has an attitude sensor system (102) and the flight instrument display (108) has a flight instrument control system (104), the attitude sensor system and the flight instrument control system having an interconnection (106) with control laws such that, when the aircraft (100) is displaced from its desired speed and heading, pilot adjustment of pitch and roll, respectively, in a manner tending to return the aircraft (100) to the desired speed and heading, causes the aircraft symbol (14) to move towards the central symmetrical square (11).
