Abstract
The present invention utilizes a conventional aircraft landing and approach indicator in conjunction with a pilot controllable television camera and supporting aircraft computer for tracking an airdrop target and displaying the locus of payload ground impact points directly on the television image of the terrain being approached by the aircraft. The airdrop information is presented in such a manner which does not distract the pilot from the basic task of flying the aircraft by providing automatic calculation and continuous automatic updating of the airdrop information with respect to meteorological and aircraft flight path characteristics.
Claims3
A method for tracking and displaying an airdrop target point to the crew of an aircraft which comprises:
- (a) displaying an image of the terrain ahead of an aircraft including the airdrop target point on an apparatus showing the aircraft flight path characteristics;
- (b) generating a line representing the locus of instantaneous impact points of an airdrop load along the terrain and superimposing said line on said image;
- (c) generating a line representing the instantaneous impact point of an airdrop load on the terrain and superimposing said line on said image;
- and,
- (d) aligning the flight path of the aircraft with said line representing the locus of instantaneous impact points until said line representing the instantaneous impact point overlays said airdrop target at which point an airdrop load is released.
