Dynamic Control Loading

With traditional flight training devices, only two of the pilot's five senses - sight and sound - are engaged. The Fidelity MOTUS device takes this to a new level with its proprietary six-degree-of-freedom motion base, providing both the vestibular sensory input sensed by pilots in actual flight as well as the turbulence functions necessary to "load" a pilot for a realistic training session. But even then the pilot doesn't "feel" the aircraft in the flight controls. Dynamic Control Loading allows the pilot to incorporate fully many of the different "feel" aspects of flight training.

• The change in required input to the flight controls depending on airspeed – for instance, as the airspeed decreases, correspondingly different control input will be required to cause a desired result.
   
• In many rotorcraft and in some modern fixed-wing applications, force trim adjustment allows the pilot to place the flight controls in the desired state…and leave them. The controls maintain the position desired by the pilot.
   
• Modern autopilot systems, particularly in helicopter simulation, move the cyclic in response to A/P commands.
   
• Many regulatory standards (FAA & JAA) require a specified static and dynamic feel of the controls to achieve desired approval levels.
   
• With the advent of "follow trim" in many aircraft, the dynamic control loader also has to be a subtle control positioner following the logic and resolution appropriate to the aircraft being simulated.

Fidelity has developed great expertise in these and other areas relating to dynamic control loading. With this dynamic control loading capability on top of its six degree-of-freedom motion base and LCD Mosaic Wall™ external visual display, Fidelity is closing the gap between inexpensive flight simulation devices and Letter-Level flight simulators costing $15-25 million more.
