This training focuses on the accomplishment of tasks that support the unit's mission. The commander must ensure that aircrews are proficient in mission-essential tasks. If an aviator is designated to fly in both crew stations, he must be evaluated in both stations during hands-on performance tests. This does not mean that the aviator will be required to perform all maneuvers in both stations. IPs, SPs, IEs, and MEs must maintain proficiency in both crew stations.
Battle rostering is the designation of two or more individuals to perform as a crew.
Consistently assigning the same crews together improves crew coordination. Commanders make battle-rostered assignments and should enforce their practice, when possible, consistent with crew resources available within the unit. They should assign an individual to a crew as soon as possible after his arrival in the unit, even if he is required to undergo qualification, refresher, or mission training. The individual may begin flying as a member of that crew while in mission training based on the recommendation of an evaluator and the approval of the commander. TC 1-210 further defines battle rostering.
