Aircrew training is designed to progress aircrews from Basic Qualification Training (BQT), to Mission Qualification Training (MQT), and finally to Continuation Training (CT). For crew-members previously qualified, BQT is replaced by Requalification Training (RQT). BQT and RQT provide the training necessary to qualify aircrew in basic position and flying duties without regard to the unitís mission. Upon completion of BQT or RQT, the crew member attains Basic Aircraft Qualification (BAQ) status. BAQ is a prerequisite for MQT. Except for General Officers, BAQ is not a long term qualification status. MQT and Formal Training Unit (FTU) Instructor Pilot Upgrade (IPUG) provide the training necessary to initially qualify or requalify aircrews in a specific position and flying duties to perform the missions assigned to a specific unit. Aircrews maintain BAQ status until completion of MQT or FTU IPUG. Completion of MQT or an FTU IPUG is a prerequisite for BMC and CMR.
