Orientation and disorientation in aviation

Area of Science:

• Aviation Psychology
• Human Factors in Flight

Background:

• Orientation is largely unconscious on the ground but requires conscious effort in flight.
• Degraded visual environments and deceptive force environments can lead to pilot disorientation.
• Unusual force environments can alter perceived object locations, potentially causing accidents.

Purpose of the Study:

• To review sources of pilot disorientation from visual and force environments.
• To challenge the traditional illusion-based approach to disorientation.
• To question the emphasis on vestibular function in disorientation.

Main Methods:

• Literature review of pilot disorientation.
• Analysis of accident data related to disorientation.
• Critique of current disorientation training and simulation methods.

Main Results:

• Disorientation arises from the interaction of visual and force environments.
• Traditional illusion-based and vestibular-focused approaches may be insufficient.
• 85% of disorientation-related accidents result from unrecognised disorientation.

Conclusions:

• Rethinking pilot disorientation training is crucial for flight safety.
• Conventional fixed-base simulators may be more effective for training disorientation scenarios than motion-based devices.
• A greater emphasis on recognizing disorientation is needed in pilot education.
