NAVIGATION ASSISTANCE INSTRUMENT FOR AN AIRCRAFT

摘要

The instrument has a liquid crystal display device (R3) extended horizontally, where centre of the display device realizes a longitudinal axis of an aircraft. A mobile marker is displaced on either side of the center of the display device indicating a flight direction of the aircraft with respect to the ground, so that an angle describes the longitudinal axis with a horizontal component of speed vector of the aircraft and the angle is positive of right side of the axis. The marker is spaced apart from the centre of the display device so that the aircraft is moved form a straight flight path.
