Abstract
Abstract A servomechanical controller for inputting prerecorded flight data to an aircraft flight simulator is provided which comprises a pair of servomotors operatively interconnected to a single output shaft connected to the flight simulator control wheel, one motor controlling simulated pitch to the wheel by imparting axial movement to the shaft, and the other motor controlling simulated roll by imparting rotation to the shaft, transducer means for sensing both angular and axial position of the shaft, and a force sensor for sensing torque and axial load on the shaft. The controller is configured for accepting analog or digital prerecorded electronic command inputs and translating those inputs to the flight simulator.

Claim 1
Independent Claim
194 words
A servomechanical controller for inputting electronically prerecorded commands to a flight simulator having a wheel and column type control, comprising: a. an output shaft operatively interconnected to said wheel to provide pitch control to said wheel in response to axial movement of said shaft, and roll control to said wheel in response to rotative movement of said shaft; b. first means, operatively interconnected to said shaft, to impart axial movement to said shaft in response to electronic inputs thereto; c. second means, operatively interconnected to said shaft to impart rotative movement to said shaft in response to electronic inputs thereto; d. first transducer means sensing the axial position of said shaft and providing an output signal thereof; e. second transducer means sensing the angular position of said shaft and providing an output signal thereof; f. a force sensor for sensing the torque and axial load on said shaft and providing output signals thereof; and g. electrical means operatively interconnecting said first means, second means, first and second transducer means, and force sensor for providing said electronic inputs to said first and second means in response to said electronically prerecorded commands and said output signals.
