In an in-flight refueling system of an aircraft having a recess therein containing a slipway leading to a fuel inlet port, an improvement is provided in the form of a guideway having a) a pair of lead-in lines on the surface of the aircraft which taper and converge towards the slipway and port and b) a plurality of dashes or bars on the surface, spaced longitudinally between the lead-in lines, a desired distance apart, to provide visual cues in aiding an operator in guiding a fuel boom and nozzle from a refueling aircraft to the slipway and port of a fuel receiving aircraft, to provide a visually more salient means to achieve a quick and effective refueling hook-up while avoiding or minimizing nozzle strikes that can damage the aircraft, the boom or its nozzle.

1. In an in-flight refueling system for an aircraft having a slipway leading to a fuel inlet port in a recess in said aircraft, the improvement comprising, a guideway having, a) a pair of lead-in lines on the surface of said aircraft which converge towards said slipway and port and b) a plurality of marks on said surface, spaced longitudinally between said lines a desired distance apart, so that said lines and marks aid in guiding a fuel boom and nozzle from a refueling aircraft to said slipway and port. 2. The guideway of claim 1 having said lines and marks forward of said slipway as the aircraft flies. 3. The guideway of claim 1 wherein said lead-in lines taper, as well as converge, in the direction of said slipway and port. 4. The guideway of claim 1 wherein the outer edges of said lead-in lines point towards said port at the far end of said slipway. 5. The guideway of claim 1 wherein the inner edges of said lead-in lines point toward the near end of said slipway. 6. The guideway of claim 1 wherein said marks are bars or dashes. 7. The guideway of claim 6 wherein said dashes or bars are mounted along a centerline between said lead-in lines. 8. The guideway of claim 7 wherein said dashes or bars are positioned laterally to said centerline. 9. The guideway of claim 8 wherein said dashes or bars are positioned orthagonally to said centerline. 10. The guideway of claim 1 wherein said recess is closed by a pair of doors which pivot toward each other on hinges, which doors when open, reveal padding over said hinges to protect them from contact with said nozzle. 11. The guideway of claim 1 wherein said lead-in lines are on the surface of the aircraft and are over two feet long and at least three of said marks are longitudinally spaced between said lead-in lines, which marks are about one foot apart. 12. The guideway of claim 1 wherein said lead-in lines which converge and said marks which are spaced between said lead-in lines, provide multi-visual cues as to distance, direction and rate of motion between said lead-in lines to said slipway and said port though one or both of them are obscured, at least in part, from the vision of the boom operator behind said boom and/or nozzle. 13. The guideway of claim 1 wherein said slipway and port are protected before and after refueling by a pair of hinged doors which pivot toward each other.
