Eight pilots flew a specified cross-country route using radio navigation in a flight simulator with simulated air traffic control. Four of the pilots flew with a low blood alcohol level (BAL; mean BAL = 20.63 mg%). Pilots’ performance was compared in terms of flying performance, navigation, and radio communication. We hypothesized that the tasks most likely to be shed as a result of alcohol impairment would be those lower down in the task prioritization hierarchy of “aviate, navigate and communicate”. This hypothesis was supported; alcohol was found to impair significantly pilots’ radio communication. Results are discussed with reference to the piloting task and the implications for alcohol regulation in aviation. © 1994, Taylor & Francis Group, LLC. All rights reserved.
