Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 113 words
An advanced fuel receptacle lighting system mounted on a tanker aircraft for aiding the refueling of a receiver aircraft, the lighting system comprising: a first black light adapted for mounting on a first tanker aircraft stabilizer; a second black light adapted for mounting on a second tanker aircraft stabilizer, the black lights illuminating an area below and behind a fuel boom and a ruddervator of the tanker aircraft; and fluorescent color markings attached to a fuel receptacle area on the receiver aircraft, the markings illuminated by the black lights for enhancing the refueling of the receiver aircraft by the tanker aircraft by improving the visual cues of depth perception of a boom operator.
Claim 2
Dependent Claim 113 words
An advanced fuel receptacle lighting system mounted on a tanker aircraft for aiding the refueling of a receiver aircraft, the lighting system comprising: a first black light adapted for mounting on a first tanker aircraft stabilizer; a second black light adapted for mounting on a second tanker aircraft stabilizer, the black lights illuminating an area below and behind a fuel boom and a ruddervator of the tanker aircraft; and fluorescent color markings attached to a fuel receptacle area on the receiver aircraft, the markings illuminated by the black lights for enhancing the refueling of the receiver aircraft by the tanker aircraft by improving the visual cues of depth perception of a boom operator.
Claim 3
Dependent Claim 54 words
The system as described in claim 1 wherein the black lights are mounted on a lower and outer surface of each of the first and second stabilizers of the tanker aircraft, the black lights aimed downwardly and slightly rearwardly of the tanker aircraft to prevent a shadowing effect from the fuel boom and ruddervator.
Claim 4
Dependent Claim 22 words
The system as described in claim 1 further including a third black light mounted on the free end of the fuel boom.
Claim 5
Dependent Claim 133 words
An advanced fuel receptacle lighting system mounted on a tanker aircraft for aiding the refueling of a receiver aircraft, the lighting system comprising: a first black light adapted for mounting on a first tanker aircraft horizontal stabilizer; a second blacklight adapted for mounting on a second tanker aircraft horizontal stabilizer, the black lights mounted on a lower and outer surface of each of the first and second stabilizers with the black lights aimed downwardly and slightly rearwardly of the tanker aircraft for illuminating an area below and behind a fuel boom and a ruddervator of the tanker aircraft; and a plurality of fluorescent color markings attached to an interior of aerial refueling doors in a fuel receptacle area of the receiver aircraft, the markings illuminated by black lights attached to the tanker aircraft.
Claim 6
Dependent Claim 133 words
An advanced fuel receptacle lighting system mounted on a tanker aircraft for aiding the refueling of a receiver aircraft, the lighting system comprising: a first black light adapted for mounting on a first tanker aircraft horizontal stabilizer; a second blacklight adapted for mounting on a second tanker aircraft horizontal stabilizer, the black lights mounted on a lower and outer surface of each of the first and second stabilizers with the black lights aimed downwardly and slightly rearwardly of the tanker aircraft for illuminating an area below and behind a fuel boom and a ruddervator of the tanker aircraft; and a plurality of fluorescent color markings attached to an interior of aerial refueling doors in a fuel receptacle area of the receiver aircraft, the markings illuminated by black lights attached to the tanker aircraft.
Claim 7
Dependent Claim 34 words
The lighting system as described in claim 4 further including a third black light attached to the free end of the fuel boom for additional illumination of a receptacle area of the receiver aircraft.
