U.S. airlines have implemented Crew Resource Management (CRM) training with an emphasis on principles and concepts that improve crew performance and flight safety. This has resulted in crew requirements that have been trained and assessed as additions to, rather than as part of, Standard Operating Procedure (SOP). Advanced Crew Resource Management (ACRM) provides a more integrated form of CRM by incorporating CRM practices with normal and emergency SOP.

ACRM is a comprehensive implementation package including the CRM procedures, training of the instructor/evaluators, training of the crews, a standardized assessment of crew performance, and an ongoing implementation process. ACRM has been designed and developed through a collaborative effort between the airline and research community. ACRM training is an ongoing development process that provides airlines with unique CRM solutions tailored to their operational demands. Design of CRM procedures is based on critical CRM principles that require emphasis in airline's specific operational environment. Procedures were developed to emphasize these CRM elements by incorporating them into SOPs for normal as well as abnormal and emergency flight situations.

ACRM is an ongoing, dynamic, development process and should not be confused with a single set of products. The Manual does present some products of the ACRM training development process, but these are to be used as examples only and should not be used as a substitute for the process. Reproducing a briefing card from another airline will not, by itself, produce the type of organization change that the ACRM training development process can.
