“…Sinacori suggested simple criteria (4,5) , which are in reasonable agreement with much of the literature (6-15) . These criteria often necessitate motion displacements greater than most training simulators can provide.…”

“…Pilots rated the simulator motion in each run with two different ratings in all three tasks. For the first rating, pilots assigned a specific fidelity level out of three levels on a Motion Fidelity Scale (MFS) (4,5) : High (H): motion sensations like those of flight. Medium (M): motion sensations are noticeably different from flight, but not objectionable. Low (L): motion sensations are noticeably different from flight and objectionable. …”

“…2, and a representative test run for each flight task, allowed the tuning of the motion configurations offline by first calculating all possible motion settings that would keep the simulator from hitting motion limits. The various OMCT fidelity regions (determined by a statistical sample of eight simulators) and the Sinacori criteria guided the motion tuning process (2,4) . The main tuning goal was to cover a reasonable area of the OMCT fidelity region, while adhering to the hexapod or VMS motion limits.…”

This paper adds data to help establish fidelity criteria to accompany the simulator motion system diagnostic test specified by the International Civil Aviation Organisation. Twelve airline transport pilots flew three tasks in the NASA Vertical Motion Simulator under four different motion conditions. The experiment used three different hexapod motion configurations, each with a different trade-off between motion filter gain and break frequency, and one large motion configuration that utilised as much of the simulator's motion space as possible. The motion condition significantly affected (1) pilot motion fidelity ratings, and sink rate and lateral deviation at touchdown for the approach and landing task, (2) pilot motion fidelity ratings, roll deviations, maximum pitch rate, and number of stick shaker activations in the stall task, and (3) heading deviation after an engine failure in the take-off task. Significant differences in pilot-vehicle performance were used to define initial objective motion cueing criteria boundaries. These initial fidelity boundaries show promise but need refinement.

“…In another, more promising, washout technique the pitching and rolling motions present angular accelerations at high frequencies (greater than 0.3 rad/sec) and linear accelerations at lower frequencies. Senicori 26 using the available information on the dynamics of the semicircular canals applied a high pass filter to allow rotations to present the rolling accelerations above 0.3 rad/sec and a low pass filter to simulate lateral acceleration by a component of gravity below 0.25 rad/sec. The difficulties one might experience in attempting to deduce the appropriate break frequency for such a washout scheme can be inferred from the variation in the apparent time constants computed earlier.…”

Data on human subjective response to angular acceleration collected on the Ames ManCarrying Rotation Device are presented, and the implications of these data to motion simulation are discussed. Threshold data have been obtained for several stimulus durations, three axes of rotation, and two response indicators. These thresholds indicate that the average pilot can be very sensitive to angular acceleration. First-order approximations to the human dynamic response to angular accelerations are derived from four experiments, and resulting time constants vary from 4 to 10 sec, depending on the observer's task. It is demonstrated that a simple static washout concept requiring continuous rotations at sub threshold levels provides essentially useless reductions in simulator travel. Another washout scheme based on the dynamics of the vestibular system is considered. The variation in the apparent dynamics derived from the psychophysical data suggest that simulator washout characteristics may have to be tailored to each simulated flight configuration or piloting task.
