Abstract
A six-axis force transducer is mounted on the flight controller and provides three independent orthogonal linear force components of the applied force and three independent orthogonal torque components of the applied force. Change in position is measured by a motorized spool connected to a high resolution shaft encoder. A small diameter thread is wound around the spool via a mechanically driven threading device. The free end of the thread is connected to a fixed point in the cockpit. The output of the transducer and the shaft encoder are fed to a microprocessor which calculates net force, in accordance with well known formula, and net position, from calibration data.
