Division (b) F1

Once an operator conversion course has been commenced, the flight crew member must not be assigned to flying duties on another type or class of aircraft until the course is completed or terminated. Crew members operating only performance class B aeroplanes may be assigned to flights on other types of performance class B aeroplanes during conversion course to the extent necessary to maintain the operation. Crew members may be assigned to flights on single-engined helicopters, during an operator conversion course on a single-engined helicopter, provided that the training is unaffected.
