Description
technical field [0001] The invention belongs to aviation instrument technology, and designs an improvement to a landing guidance device. Background technique [0002] At present, the landing guidance devices all use the principle of electromagnetic induction, and the two command sticks in the pitch and tilt directions are used together on the horizon gauge to guide the aircraft to land. During the flight, the command stick is hidden in the horizon gauge display window. When the pilot gives After the landing signal is issued, the command stick appears in the display window of the horizon indicator. The position of the aircraft relative to the destination is different, and the control voltage of the command stick will change, so that the command stick is in a different position in the window. Position determines the position of the aircraft relative to the destination. [0003] The current landing guidance devices have disadvantages such as complex structure, poor indication ...
