This study was conducted to determine the cost of training out of community Naval Aviators (Pilots and Naval Flight Officers) into the P-3 Reserve Force. It was designed to assess the cost of training the average Pilot or Naval Flight Officer whose original fleet experience was in an aircraft other than the P-3, and to provide to decision makers information regarding which communities contribute most efficiently to the P-3 Reserve Force. Additionally, the use of these out of community aviators was measured in order to examine manning problems at the P-3 Reserve drilling sites.
