Abstract
Abstract On one side of a portable case are mounted aircraft instruments, a control wheel and a throttle to simulate the instrument panel and controls of an airplane. The control wheel and throttle are movable and interconnected by compound lever mechanism which is connected to actuate the tachometer, the airspeed indicator, the artificial horizon elevationally, the rate-of-climb indicator and the altimeter. The control wheel is connected independently of the compound lever to actuate the turn indicator, the tilting of the artificial horizon, the directional gyro, a VHF omnirange indicator, a course recorder and an automatic direction finder.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
90 words
An aircraft instrument operation trainer comprising a simulated flight control, a simulated engine control, a flight condition indicating instrument, and drive means connected to drive said instrument and including a main lever connected to said simulated flight control and an auxiliary lever pivotally mounted on one arm of said main lever at a location spaced from the rotative axis of said main lever, said auxiliary lever being connected to said simulated engine control for actuation of said instrument both by said simulated flight control and by said simulated engine control.
Claim 2
Dependent Claim
90 words
An aircraft instrument operation trainer comprising a simulated flight control, a simulated engine control, a flight condition indicating instrument, and drive means connected to drive said instrument and including a main lever connected to said simulated flight control and an auxiliary lever pivotally mounted on one arm of said main lever at a location spaced from the rotative axis of said main lever, said auxiliary lever being connected to said simulated engine control for actuation of said instrument both by said simulated flight control and by said simulated engine control.
Claim 3
Dependent Claim
23 words
The trainer defined in claim 1, in which the flight condition indicating instrument is an air speed indicator connected to the auxiliary lever.
Claim 4
Dependent Claim
22 words
The trainer defined in claim 1, in which the flight condition indicating instrument is a rate-of-climb indicator connected to the auxiliary lever.
Claim 5
Dependent Claim
21 words
The trainer defined in claim 1, in which the flight condition indicating instrument is an altimeter connected to the auxiliary lever.
Claim 6
Dependent Claim
83 words
An aircraft instrument operation trainer comprising a simulated flight control including a shaft mounted for rotation and for lengthwise reciprocation, a turn-indicating instrument, and actuating means for said turn-indicating instrument including an elongated member extending parallel to said shaft and held against lengthwise movement and a member movable lengthwise of said elongated member by lengthwise movement of said shaft and operable to move said elongated member transversely of its length by rotation of said shaft in various lengthwise reciprocated positions of said shaft.
Claim 7
Dependent Claim
83 words
An aircraft instrument operation trainer comprising a simulated flight control including a shaft mounted for rotation and for lengthwise reciprocation, a turn-indicating instrument, and actuating means for said turn-indicating instrument including an elongated member extending parallel to said shaft and held against lengthwise movement and a member movable lengthwise of said elongated member by lengthwise movement of said shaft and operable to move said elongated member transversely of its length by rotation of said shaft in various lengthwise reciprocated positions of said shaft.
Claim 8
Dependent Claim
82 words
An aircraft instrument operation trainer comprising a simulated flight turn control, a recording surface, steerable recording means movable over said surface, dogleg linkage carrying saId steerable recording means, orienting means carried by said dogleg linkage, drive means for effecting movement of said recording means over said recording surface, and steering means actuated by said simulated flight turn control for driving said orienting means to alter the direction of movement of said recording means over said recording surface effected by said drive means.
Claim 9
Dependent Claim
82 words
An aircraft instrument operation trainer comprising a simulated flight turn control, a recording surface, steerable recording means movable over said surface, dogleg linkage carrying saId steerable recording means, orienting means carried by said dogleg linkage, drive means for effecting movement of said recording means over said recording surface, and steering means actuated by said simulated flight turn control for driving said orienting means to alter the direction of movement of said recording means over said recording surface effected by said drive means.
Claim 10
Dependent Claim
35 words
The trainer defined in claim 6, further including an aircraft heading-indicating instrument, and instrument-actuating means operated by movement of the recording means over the recording surface and operable to effect operation of the heading-indicating instrument.
Claim 11
Dependent Claim
15 words
The trainer defined in claim 7, in which the heading-indicating instrument is an ADF instrument.
Claim 12
Dependent Claim
31 words
The trainer defined in claim 8, in which the instrument-actuating means includes means operated by the simulated flight turn control independently of movement of the recording means over the recording surface.
Claim 13
Dependent Claim
14 words
The trainer defined in claim 8, in which the instrument is a VOR indicator.
Claim 14
Dependent Claim
33 words
The trainer defined in claim 10, in which the VOR indicator includes a shiftable ''''to'''' and ''''from'''' display and the instrument-actuating means includes means for shifting the display to alter the word displayed.
Claim 15
Dependent Claim
34 words
The trainer defined in claim 10, and manually-operable means connected to the instrument-actuating means for counteracting the effect of the recording means on the instrument-actuating means tending to effect operation of the VOR indicator.
Claim 16
Dependent Claim
50 words
The trainer defined in claim 12, in which the instrument-actuating means includes a cam member and a cam-follower member cooperating with said cam member, one of said members being movable by movement of the recording means over the recording surface and the other member being movable by the manually-operable means.
Claim 17
Dependent Claim
157 words
An aircraft instrument operation trainer comprising a simulated flight turn control, a recording surface, steerable recording means movable over said surface, drive means for effecting movement of said recording means over said recording surface, steering means actuated by said simulated flight turn control for altering the direction of movement of said recording means over said recording surface effected by said drive means, a VOR indicator, instrument-actuating means operated by movement of said recording means over said recording surface and operable to effect operation of said VOR indicator, and manually-operable means connected to said instrument-actuating means for counteracting the effect of said recording means on said instrument-actuating means tending to effect operation of said VOR indicator, said instrument-actuating means including a cam member and a cam-follower member cooperating with said cam member, one of said members being movable by movement of said recording means over said recording surface and the other member being movable by said manually-operable means.
Claim 18
Dependent Claim
157 words
An aircraft instrument operation trainer comprising a simulated flight turn control, a recording surface, steerable recording means movable over said surface, drive means for effecting movement of said recording means over said recording surface, steering means actuated by said simulated flight turn control for altering the direction of movement of said recording means over said recording surface effected by said drive means, a VOR indicator, instrument-actuating means operated by movement of said recording means over said recording surface and operable to effect operation of said VOR indicator, and manually-operable means connected to said instrument-actuating means for counteracting the effect of said recording means on said instrument-actuating means tending to effect operation of said VOR indicator, said instrument-actuating means including a cam member and a cam-follower member cooperating with said cam member, one of said members being movable by movement of said recording means over said recording surface and the other member being movable by said manually-operable means.
