PCT No. PCT/EP95/00661 Sec. 371 Date Aug. 30, 1996 Sec. 102(e) Date Aug. 30, 1996 PCT Filed Feb. 23, 1995 PCT Pub. No. WO95/23734 PCT Pub. Date Sep. 8, 1995An apparatus for guiding the pilot of an aircraft approaching its stipulated parking position in a straight line with a distance measuring device, which looks at the aircraft from the front in the direction of movement and which determines the actual position of the aircraft, and with an indicating device, which tells the pilot the distance remaining between the actual and parking positions, is characterised in that at least a 2D laser sensor is provided as the distance measuring device which surveys the front of an aircraft point by point in a (not horizontal) plane within a predetermined viewing angle and in successive measuring sweeps and which resolves each measuring point into its horizontal and vertical coordinates and from the horizontal coordinates, determined in a measuring sweep, of such measuring points, the vertical coordinates of which fall within at least one height range which is separately definable between the threshold values for each aircraft type, forms the average value as the actual position of the aircraft and compares it with the parking position which is also defined as a horizontal coordinate and produces a signal for the indicating device in dependence on the distance between the actual position and the parking position.
