Opinicus Control Loading
The column, wheel and pedal forces are provided by Opinicus Corp. REALFeel 4000X force loader units. Two autothrottle channels are provided by REALFeel 2000RC force loader units.
The forces are generated by electric DC servo motors coupled to a two stage, low inertia, zero backlash speed reducer which in turn is linked via a push pull rod to a force transducer and the flight controls linkage. The autothrottles are moved through a backdrive feature to their desired deflections. The system is operated by a digital computer which is coupled to the simulator's flight computer via a fiber optic cable and a reflective memory interface. The manufacturer specifies a force loop frequency response of greater than 100Hz.
The 4000X control loaders can produce a continuous force output of ±412 lb and much larger peak values. Their stroke is ±2 in. The control column has a travel range of 5.5 in (14cm) forward and 9.3 in (24 cm) aft. The control wheel has a travel range of ±120°. The pedals have a travel range of ±2.6 in (6.6 cm). The 2000RC control loaders can produce a continuous torque output of ±XXX ft.lb with a continuous rotational capability.
