Abstract:

The direction of future spatial disorientation SD research and training is shaped primarily by the outcome of formal investigation of aircraft accidents and incidents. However, another source of vital information is aircrewss experience of SD that does not result in reported incidents. In order to access these experiences, Project Group 117 of Working Partly WP 61, Aircrew Standardization Co-ordinating Committee ASCC developed a SD survey postal questionnaire INFO PUB 611175, with the aim of providing a standard for mat for data collection and analysis. This paper reports the findings of a preliminary survey of UK aircrew. Method For the UK survey, a total of 1320 questionnaires were distributed to 5 Naval Air Squadrons, 22 Joint Helicopter Command Units and 7 Royal Air Force stations. Seven hundreds and fifty-two questionnaires, comprising responses from 606 pilots and 146 navigators were returned. Results Analysis was conducted primarily on the pilot data. The most frequently experienced SD episodes were the leans by 92 of respondents, loss of horizon due to atmospheric conditions 82, misleading altitude cues 79, sloping horizon 75 and SD arising from distraction 65. When asked to rate the severity of their most recent SD episode, 3.5 21 categorized their incident as severe flight safety was at risk. In general, the frequency of SD episodes and rating of severity of the worst ever SD episode were positively related to flying experience hours-on-type, total hours p0.05. Overall, pilots who had received in-flight SD training reported more episodes of SD than those who had not participated in this training p 0.05.
