Disorientation phenomena in naval helicopter pilots.

Area of Science:

• Aviation Psychology
• Human Factors Engineering
• Naval Aviation Safety

Background:

• Pilot disorientation is a known issue in aviation.
• Specific disorientation challenges for naval helicopter pilots operating at sea and landing on moving platforms remain under-investigated.
• Understanding these unique challenges is crucial for enhancing flight safety.

Purpose of the Study:

• To investigate the incidence and contributing factors of disorientation in naval helicopter pilots.
• To identify factors specific to maritime operations and those common to all aircraft types.
• To explore potential countermeasures for pilot disorientation.

Main Methods:

• An anonymous questionnaire was distributed to 104 active naval helicopter pilots.
• Pilots reported experiences of severe disorientation.
• Data analysis identified precipitating factors and their frequency.

Main Results:

• 56% of pilots reported at least one episode of severe disorientation.
• 8.6% of pilots reported five or more episodes of severe disorientation.
• Specific factors related to over-water and moving-deck operations were identified, alongside common aviation factors.

Conclusions:

• Naval helicopter operations at sea present unique disorientation risks.
• Both unique and common factors contribute to pilot disorientation.
• Developing targeted countermeasures is essential for improving safety in naval helicopter operations.
