Abstract : The purpose of this study was to determine if the illness rates of nonpilot air crewmembers are different from pilots. Interest in aircrew illness rates began when schedulers and flight surgeons noticed that frequently there were insufficient numbers of healthy flight engineers to staff the mission. When the literature on aircrew illness rates was reviewed, few studies were found. This study involved the compilation of illness data including diagnosis job title (pilot (P), flight engineer (FE), loadmaster (L)), date of illness onset, and date of recovery for a military airlift wing in the southeastern United States over a two year period. Total time lost rates were calculated for each crew position for all illness and the seven most frequent diagnostic categories. Pilots were used as the comparison (referent) group. The database identified 1976 illnesses (events) in 569,969 person-days at risk. Time lost rates (days lost per 1000 person-days at risk) were significantly higher for flight engineers (56.2, p .001) and loadmasters (64.0, p .001) when compared to pilots (29.8). Incidence rates (new illness events per 1000 person-days at risk) were significantly higher for flight engineers (3.87, p.001) and loadmasters (4.07, p.001) than for pilots (2.76). Mean duration of illness was also longer for flight engineers at 8.4 days, and loadmasters at 9 days, than pilots at 6.6 days.
