Abstract

Abstract A self-contained, landing gear position simulator for use in an aircraft includes first and second panels oriented in different planes. Five lamps and a manually operable switch are mounted on the first panel and four manually operable switches are mounted on the second panel. When the switch on the first panel is moved to a first position to simulate a control action of retracting the aircraft landing gear, a first lamp on the first panel is lighted, and when the switch is moved to a second position to simulate a control action of extending the aircraft''s landing gear, the first lamp is extinguished and second, third and fourth lamps are lighted. When one of the four switches on the second panel is operated, a corresponding one of the first, second, third or fourth lamps is prevented from being lighted. The simulator also includes apparatus responsive to a predetermined air speed indication of the aircraft for lighting a fifth lamp.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 269 words
A landing gear position simulator for use in an aircraft capable of seating a student pilot and an instructor and having apparatus for generating an indication of aircraft speed comprising a housing having at least first and second exterior surfaces oriented in different planes, said housing being positionable in the aircraft so that the first surface is viewable by a student pilot and the second surface is viewable by an instructor, first, second, third and fourth lamps mounted on said first surface, said first lamp, when lighted, representing that the left and right landing gear are in the retracted position, and said second and third lamps, when lighted, representing that left and right landing gear respectively of the aircraft are in the extended position, a manually operable landing gear control simulation switch mounted on said first surface, said switch, when operated to a first position, representing a control action to simulate movement of the landing gear to a retracted position, and, when operated to a second position, representing a control action to simulate movement of the landing gear to an extended position, means for supplying power to illuminate said first lamp when said switch is in the first position and for supplying power to illuminate said second and third lamps when said simulation switch is in the second position, means responsive to an aircraft speed indication for supplying power to illuminate said fourth lamp if said simulation switch is in the first position, and first, second and third manually operable switches mounted on said second surface for selectively preventing the lighting of said first, second and third lamps respectively.
Claim 2
Dependent Claim 269 words
A landing gear position simulator for use in an aircraft capable of seating a student pilot and an instructor and having apparatus for generating an indication of aircraft speed comprising a housing having at least first and second exterior surfaces oriented in different planes, said housing being positionable in the aircraft so that the first surface is viewable by a student pilot and the second surface is viewable by an instructor, first, second, third and fourth lamps mounted on said first surface, said first lamp, when lighted, representing that the left and right landing gear are in the retracted position, and said second and third lamps, when lighted, representing that left and right landing gear respectively of the aircraft are in the extended position, a manually operable landing gear control simulation switch mounted on said first surface, said switch, when operated to a first position, representing a control action to simulate movement of the landing gear to a retracted position, and, when operated to a second position, representing a control action to simulate movement of the landing gear to an extended position, means for supplying power to illuminate said first lamp when said switch is in the first position and for supplying power to illuminate said second and third lamps when said simulation switch is in the second position, means responsive to an aircraft speed indication for supplying power to illuminate said fourth lamp if said simulation switch is in the first position, and first, second and third manually operable switches mounted on said second surface for selectively preventing the lighting of said first, second and third lamps respectively.
Claim 3
Dependent Claim 43 words
A simulator as in claim 1 wherein the first lamp is of a certain color, the second and third lamps are of a different color, and the fourth lamp is of a color different from the colors of the first through third lamps.
Claim 4
Dependent Claim 32 words
A simulator as in claim 1 further comprising a third exterior surface, and a test switch mounted on said third surface which, when operated, supplies power to illuminate all of said lamps.
Claim 5
Dependent Claim 212 words
A landing gear position simulator for use in an aircraft capable of seating a student pilot and an instructor and including apparatus for generating an indication of the aircraft speed comprising first and second panels positioned in different planes, said simulator being positioned in the aircraft so that the student pilot may view the first panel and the instructor may view the second panel, first, said second and third indicators, when activated, representing that left and right landing gear respectively of the aircraft are in the extended position, and said first indicator, when activated, representing that the landing gear are in the retracted position, a manually operable landing gear control simulation switch mounted on said first panel, wherein movement of said switch to a first position simulates a control action to retract the landing gear and movement of said switch to a second position simulates a control action to extend the landing gear, first, second and third manually operable switches mounted on said second panel for selectively preventing the activation of said first, second and third visual indicators respectively, and a fourth visual indicator mounted on said first panel, and means responsive to an aircraft speed indication for activating said fourth visual indicator if said simulation switch is in the first position.
Claim 6
Dependent Claim 212 words
A landing gear position simulator for use in an aircraft capable of seating a student pilot and an instructor and including apparatus for generating an indication of the aircraft speed comprising first and second panels positioned in different planes, said simulator being positioned in the aircraft so that the student pilot may view the first panel and the instructor may view the second panel, first, said second and third indicators, when activated, representing that left and right landing gear respectively of the aircraft are in the extended position, and said first indicator, when activated, representing that the landing gear are in the retracted position, a manually operable landing gear control simulation switch mounted on said first panel, wherein movement of said switch to a first position simulates a control action to retract the landing gear and movement of said switch to a second position simulates a control action to extend the landing gear, first, second and third manually operable switches mounted on said second panel for selectively preventing the activation of said first, second and third visual indicators respectively, and a fourth visual indicator mounted on said first panel, and means responsive to an aircraft speed indication for activating said fourth visual indicator if said simulation switch is in the first position.
