Training Circular (TC) 3-04.52 consolidates Guardrail and Guardrail/common sensor (GRCS) aircraft into one aircrew training manual (ATM) and standardizes aircrew training programs (ATPs) and flight evaluation procedures. This manual provides specific guidelines for executing RC-12 series aircrew training. The RC-12 ATM establishes crewmember qualification training, refresher training, mission training, continuation training, and evaluation requirements. This manual applies to all Active Army, the United States (U.S.) Army National Guard (ARNG) and U.S. Army Reserve (USAR) RC-12 series crewmembers and their commanders. This manual is not a stand-alone document. All of the requirements contained in Army regulation (AR) 600-105, AR 600-106, National Guard regulation (NGR), NGR 95-210, and TC 3-04.11 must be met. If differences exist between the maneuver descriptions in the operator manuals and this publication, this publication is the governing authority for training and flight evaluation purposes. Implementation of this publication conforms to AR 95-1 and TC 3-04.11. If a conflict exists between this publication and TC 3-04.11 the ATP commander determines the method of accomplishment based upon the requirement and the unit's mission as to which manual takes precedence. This manual in conjunction with the ARs and TC 3-04.11 will help aviation commanders at all levels develop a comprehensive ATP. Using this ATM, commanders ensure that individual crewmember and aircrew proficiency is commensurate with their units' mission and that aircrews routinely employ standard techniques and procedures. Standardization officers, evaluators and unit trainers (UTs) will use this manual and TC 3-04.11 as the primary tools to assist the commander in developing and implementing their ATP. Crewmembers will use this manual as a "how to" source for performing crewmember duties. It provides performance standards and evaluation guidelines so that crewmembers know the level of performance expected. Each task has a description of the proper procedures for completion to meet the standard.
