General Aviation Pilot Performance Following Unannounced In-Flight Loss of Vacuum System and Associated Instruments in Simulated Instrument Meteorological Conditions

[摘要] Forty-one instrument-rated pilots were exposed to an unannounced failure of attitude and heading instrumentation during flight in single-engine general aviation aircraft: 25 in a Piper Archer PA-28 and 16 in a Beechcraft Bonanza A36. The PA-28 flights consisted of three groups: (1) Group A � a failure of the attitude indicator (AI) and directional gyro (DG), (2) Group B � same as Group A but received 30 minutes of partial-panel instruction in a personal-computer-based aviation training device (PCATD) prior to the flight, and (3) Group C � same as group A but had a failure-annunciator light (vacuum) on the panel. The A36 flights consisted of two groups: (1) Group A � a failure of the AI only, (2) Group B � a failure of the AI and the horizontal situation indicator (HSI).
