Crew Resource Management Training

Crew Resource Management (CRM) training — using all available human, hardware, and information resources to fly safely.

About this document

AC 120-51, Crew Resource Management Training, is the FAA's foundational guidance on CRM. It defines CRM as the effective use of all available resources — flight-deck crew, other personnel, hardware, and information — and describes how carriers should build CRM training covering communication, situational awareness, workload management, decision-making, and error management.

The CRM concepts here inform single-pilot resource management as well, making it broadly relevant beyond airline operations.
