Analytical Assessment of Flight Simulator Fidelity Using Pilot Models

摘要

A simplified approach for modeling pilot pursuit control behavior is adopted for use in assessing the fidelity ofnflight simulators. The model includes proprioceptive, visual, and vestibular cueing. The model differs from previousnsimulator fidelity applications in that pursuit, as opposed to compensatory pilot behavior, is modeled. Innapproximate fashion, the model can account for the effects of task interference, degraded motion and visual cues,nvehicle modeling errors, differing levels of pilot control aggressiveness, and to a limited extent, pilot skill level. Anfidelity metric similar to one previously discussed in the literature is exercised with three vehicles and tasks: a fighternaircraft in a tail-chase tracking task, a small rotorcraft in a near-hover repositioning task, and a large rotorcraft innacceleration/deceleration and departure/abort tasks. The fidelity assessment procedure is shown to be sensitive tonchanges in vehicles, tasks, and simulator limitations in these disparate examples.
