By Sarina Houston Definition: Crew Resource Management is also known as Cockpit Resource Management, or just CRM.CRM is a cockpit management concept that involved a pilot's thorough use of all available resources, both inside the cockpit and outside.History: Crew resource management emerged in the late 1970s in response to NASA accident investigation research.

Captains were put on pedestals and inferior pilots felt it was disrespectful to question them.

This created a workplace atmosphere that was not conducive to teamwork, and led to many accidents.

The purpose of CRM at this time was to gain an environment of equal respect, teamwork and cooperation to safely accomplish the mission of the flight.

Later CRM models followed similar teachings, but also incorporated better decision-making skills overall.

Error management became the focus of late CRM training modules.

Safety statistics dictate that humans are the main source of error; therefore, pilots must learn to recognize potential errors and control errors when they do occur.

Most recently, CRM has evolved into teaching pilots risk management strategies, focusing on workload management, recognizing hazardous attitudes or patterns, maintaining situational awareness, and communicating effectively in order to operate efficiently and safely in all aspects of flight.

NASA researchers found that deficiencies in interpersonal communication skills, decision making and leadership in the cockpit were the main causes of various accidents, so they put together a program to encourage teamwork and resource management.

In the 1970s, much of the focus of CRM was on the pilot/copilot relationship.

It seemed that there were some airline captains that thought very little of their co-workers.

There were also many first officers that didn't feel like they could stand up to their captain when they didn't agree with his or her actions.
