the steady, cruise regime of a fighter aircraft may be able to be well simulated within these limitations, in aerial combat situations flight maneuvers are executed in a very rapid manner to physical extremes. In these scenarios, there is not time for a washout filter to react to bring the motion system back to its range equilibrium resulting in the motion system quickly hitting its range of movement limitations and effectively ceasing to accurately simulate the dynamics. It is for this reason that motion and washout filter based systems are often reserved for those that experience a limited range of flight conditions. The filters themselves may also introduce false cues, defined as: 1) a motion cue in the simulator that is in the opposite direction to that in the aircraft, 2) a motion cue in the simulator when none was expected in the aircraft, and 3) a relatively high-frequency distortion of a sustained cue in the simulator for an expected sustained cue in the aircraft. The previous definition groups together all of the cueing errors that lead to very large decreases in perceived motion fidelity. Six potential sources of false cues are: Software or Hardware Limiting:When the simulator approaches a displacement limit, two methods of protection are provided: 1) software limiting and 2) hardware limiting. In either case the simulator is decelerated to prevent damage to the motion system. Large false cues are often associated with this deceleration. Return to Neutral: This false cue is attributed to the overshoot of the high-pass filters to step-type inputs. This type of response only occurs if second- or third-order high-pass filters are used. G-Tilt Tilt-Coordination Angular Rate Tilt-Coordination Remnant: For sustained specific force input in sway or surge, the simulator will achieve a steady-state pitch or roll angle because of tilt-coordination. If the input ends abruptly, then the highpass specific force response will initially cancel out the specific force associated with the tilt, but only for a brief time before the restricted simulator displacement prohibits translational acceleration of the simulator. If the tilt is removed quickly, then a tilt-coordination angular rate false cue will occur; if not, the remaining tilt will create a sensation of acceleration, called a tilt-coordination remnant false cue. Tilt Coordination Angular Acceleration: This false cue is caused by the angular acceleration generated by the tilt-coordination occurring about a point other than the pilot's head. The angular acceleration combined with
