INTRODUCTION OF THE AIRCREW ROTATION SYSTEM

The problem of daily servicing of aircraft, as distinct from repair and overhaul, was met by the formation of servicing units. The first New Zealand squadrons to go overseas, both bomber-reconnaissance and fighter, went as complete units taking their servicing staffs as well as aircrews. American experience had shown, however, particularly with regard to fighter squadrons, that aircrews could remain in the combat area only for a short time if they were page 166 to stay efficient. The RNZAF decided to follow the American practice, giving them only short tours of duty. In May 1943 it was laid down that the tour for fighter pilots should consist of six weeks at Santo on training and garrison duties, followed by six weeks in the combat area. At the end of a tour they returned to New Zealand for leave and training before proceeding on another. The length of each stage of the tour was modified from time to time as operational conditions changed, but the principle remained the same for the rest of the war.

The practice of giving aircrew short tours in the tropics contributed greatly towards efficiency in the air and to a low wastage rate. It was costly in movement and loss of time, but it ensured a high standard and also reduced the necessity for training new crews.
