A survey of the combat-ready SAC navigatorradar navigator crew force for the B-52GH fleet was conducted in July 1976. The data reported relate to variables associated with crew experience age, rank, flying hours, instructor status, months together as a team, etc.. Team variables were derived from the data on individual crew members and an intercorrelation table was computed. Since these data were to be used for selecting a sample of crews from G model bases not having an Automated Offset Unit by February 1977, the overall crew force was broken down into four subgroups G vs. H bases, with and without AOU for some analysis. An analysis of variance was performed using total flying hours as the dependent variable. Crew types ready, lead, and select were found to have statistically signifficant differences in flying hours for all contrasts. Bases which had AOU equipped G model aircraft were found to have a significantly larger number of total flying hours. Failure to reject the null hypothesis for non-AOU equipped G model bases was interpreted to imply that the sample from this sub-population would be representative of the overall crew force of total flying hours.
