Proper nutrition is essential to meet the physiological demands of flying. Poor eating habits can be a contributory cause for decreased pilot performance. Research has shown that low blood glucose levels, especially after a fasting period, contribute toward decreased cognitive function. This is especially relevant for aircrew personnel given the physiological demands placed upon them. Previous work has indicated that some USAF fighter pilots do not regularly eat breakfast, an essential meal for restoring blood glucose after an overnight fast. Due to the detriment of low blood glucose on certain cognitive tasks, we investigated if skipping breakfast would adversely impact flying performance. Using a cross-over double-blinded design, eight individuals were provided alternating liquid breakfast drink conditions (low carbohydrate, high carbohydrate) and then tested on unusual attitude recovery using computerized flight simulator software and susceptibility to spatial disorientation using a motion based flight simulator (GAT-II flight trainer). Comparing mean response times, data analysis did not detect any significant differences between groups. Additionally, mean pilot errors between drink conditions were insignificant. Although analysis revealed equivocal results and suggest no adverse effects under the aforementioned conditions, there were trends that existed between the groups in terms of increased mean response times for those ingesting the lower carbohydrate drink. Additional study is warranted to fully evaluate the effects of the hypoglycemic state on pilot performance.
