Abstract: A display panel of selectively operated pilot guiding lights is mounted on the belly of a fuel tanker aircraft for guiding a piloted receiver aircraft into proper orientation for an in-flight refueling link-up in which a fuel dispensing boom that projects rearwardly and downwardly from the belly of the tanker aircraft is coupled to a complimentary, refueling receptacle mounted above the cockpit of the receiver aircraft. The guidance-lights are selectively and automatically operated by computer processed position signals developed by an optical position sensor system that continuously monitors the position of the receiver aircraft relative to the boom. A first set of guidance-lights are disposed lengthwise of the aircraft to form a fore-aft position indicating array, and a second set of lights are disposed in a cross-shaped array for providing a coordinated visual display of elevational and azimuthal position.
