What is crew resource management?

- Keeping the crew as small as possible to cut down on communication
Show the answer
C. Making effective use of all available people, equipment and information
Crew resource management is the effective use of all available resources (human, hardware and information) before and during flight. Loading every task onto one person is the opposite of the idea.
