Brief Summary

The purpose of this research is to investigate how different levels of simulator motion fidelity affect pilot performance in two different flight tasks while using a head mounted display (or mixed-reality headset) for out-the-window (OTW) visuals. Three levels of motion fidelity will be studied: 1) no motion, 2) small hexapod motion, and 3) one-to-one vehicle motion.

Conditions

Healthy

Outcome Measures

Primary Outcomes (3)

• Time to Complete Flight Task Maneuver (Averaged over Repetitions)

  Time needed to complete (a portion of) the flight task measured against desired and adequate performance criteria: Heliport Approach Task - Battery time remaining (desired \>=20:00 min, adequate \>=19:40 min) Lateral Reposition and Hold Task \- Reposition completion time (desired \<=25 s, adequate \<=35 s)

  Day 1

• Accuracy of the Flight Task Maneuver (Averaged over Repetitions)

  Accuracy of the maneuver during (a portion of) the flight task measured against desired and adequate performance criteria: Heliport Approach Task * Glideslope deviation (desired +-0.7 deg, adequate +-2.1 deg) * Localizer deviation (desired +-0.7 deg, adequate +-2.1 deg) * Helipad boundary crossing height (desired +-10 ft, adequate +-20 ft) * Helipad boundary crossing speed (desired +-5 kts, adequate +-10 kts) * Helipad center deviation (desired +-20 ft, adequate +-60 ft) Lateral Reposition and Hold Task * Ground track deviation (desired +-5 ft, adequate +-10 ft) * Target ground speed deviation (desired +-5 kts, adequate +-8 kts) * Altitude deviation (desired +-5 ft, adequate +-10 ft) * Heading deviation (desired +-10 deg, adequate +-15 deg) * Hover point lateral and longitudinal deviation (desired +-5 ft, adequate +-10 ft)
