In aviation safety , threat and error management ( TEM ) is an overarching safety management approach that assumes that pilots will naturally make mistakes and encounter risky situations during flight operations. Rather than try to avoid these threats and errors, its primary focus is on teaching pilots to manage these issues so they do not impair safety. Its goal is to maintain safety margins by training pilots and flight crews to detect and respond to events that are likely to cause damage (threats) as well as mistakes that are most likely to be made (errors) during flight operations.

86-547: A DC-8 crew running out of fuel over Portland, Oregon, while troubleshooting a landing gear problem. The term "cockpit resource management"—which was later generalized to "crew resource management"—was coined in 1979 by NASA psychologist John Lauber, who for several years had studied communication processes in cockpits. While retaining a command hierarchy, the concept was intended to foster a less-authoritarian cockpit culture in which co-pilots are encouraged to question captains if they observed them making mistakes. CRM grew out of
129-477: A contributing factor that led to the 2009 fatal crash into the Atlantic Ocean of Air France Flight 447 from Rio de Janeiro to Paris. The final report concluded the aircraft crashed after temporary inconsistencies between the airspeed measurements—likely due to the aircraft's pitot tubes being obstructed by ice crystals—caused the autopilot to disconnect, after which the crew reacted incorrectly, causing
172-911: A free kit of resources. Operating train crews at the National Railroad Passenger Corporation (Amtrak) in the United States are instructed on CRM principles during yearly training courses. CRM has been adopted by merchant shipping worldwide. The STCW Convention and STCW Code, 2017 edition, published by the I.M.O. states the requirements for Bridge Resource Management and Engine Room Resource Management training. These are approved shore-based training, simulator training, or approved in-service experience. Most maritime colleges hold courses for deck and engine room officers. Refresher courses are held every five years. These are referred to as Maritime resource management . Following its successful use in aviation training, CRM
215-523: A highly trained observer. LOSA data is used to assess the effectiveness of an organization's training program and to find out how trained procedures are being implemented in day-to-day flights. Threat and error management is an important element in the training of competent pilots that can effectively manage in-flight challenges. Many strategies have been developed (e.g. training, teamwork, reallocating workload) that were focused on improving on stress , fatigue , and error . Flight crew training stressed

344-596: A standardized communication protocol to indicate a problem led to the captain dismissing the first officer's warnings. Both pilots were also overburdened with making preparations to land, resulting in neither being able to pay full attention to what was happening. First Air increased the time dedicated to CRM in their training as a result of the accident, and the CTSB recommended regulatory bodies and airlines to standardize CRM procedures and training in Canada. The success of
387-476: Is a set of training procedures for use in environments where human error can have devastating effects. CRM is primarily used for improving aviation safety and focuses on interpersonal communication , leadership , and decision making in aircraft cockpits. Its founder is David Beaty , a former Royal Air Force and a BOAC pilot who wrote The Human Factor in Aircraft Accidents (1969). Despite

When CRM techniques are applied to other arenas, they are sometimes given unique labels, such as maintenance resource management, bridge resource management, or maritime resource management . CRM training encompasses a wide range of knowledge, skills, and attitudes including communications, situational awareness, problem solving, decision making, and teamwork; together with all
473-451: Is an imminent threat to current operations or who is causing the threat. In the past, SCP data were based on investigation of accidents or incidents, experiences, and intuitions but nowadays SCP focuses more on the precursors to accidents. There are several steps involved in conducting SCP: An unnamed airline conducted base-line observations from 1996 to 1998 using the defined SCP and LOSA data to improve its organization's safety culture and

TEM also considers technical (e.g. mechanical) and environmental issues, and incorporates strategies from Crew Resource Management to teach pilots to manage threats and errors. The TEM framework
559-739: Is now a mandated requirement for commercial pilots working under most regulatory bodies, including the FAA (US) and EASA (Europe). The NOTECHS system is used to evaluate non-technical skills. Following the lead of the commercial airline industry, the US Department of Defense began training its air crews in CRM in the mid 1980s. The U.S. Air Force and U.S. Navy require all air crew members to receive annual CRM training to reduce human-error-caused mishaps. The U.S. Army has its own version of CRM called Aircrew Coordination Training Enhanced (ACT-E). When

Susan Parson, the editor of the Federal Aviation Administration (FAA) Safety Briefing wrote; "Clearly, the QF32 crew's performance was a bravura example of the professionalism and airmanship every aviation citizen should aspire to emulate". Carey Edwards, author of Airmanship wrote: Their crew performance, communications, leadership, teamwork, workload management, situation awareness, problem solving and decision making resulted in no injuries to
731-599: The South Canyon Fire in Colorado. From this paper, a movement was initiated in the Wildland and Structural Fire Services to apply CRM concepts to emergency response situations. Various programs have since been developed to train emergency responders in these concepts and to help track breakdowns in these stressful environments. The International Association of Fire Chiefs published its first CRM manual for
774-479: The 1977 Tenerife airport disaster , in which two Boeing 747 aircraft collided on the runway, killing 583 people. A few weeks later, NASA held a workshop on the topic, endorsing this training. In the US, United Airlines was the first airline to launch a comprehensive CRM program, starting in 1981. By the 1990s, CRM had become a global standard. United Airlines trained their flight attendants to use CRM in conjunction with
817-533: The 450 passengers and crew. QF32 will remain as one of the finest examples of airmanship in the history of aviation. The basic concepts and ideology of CRM have proven successful in other related fields. In the 1990s, several commercial aviation firms and international aviation safety agencies began expanding CRM into air traffic control, aircraft design, and aircraft maintenance. The aircraft maintenance section of this training expansion gained traction as Maintenance Resource Management (MRM). To attempt to standardize
860-607: The Defense Safety Oversight Council (DSOC) of the U.S. Department of Defense (DoD) recognized the mishap-prevention value of this maintenance safety program by partially funding a variant of ANG MRM for training throughout the U.S. Air Force. This ANG initiated, DoD-funded version of MRM became known as Air Force Maintenance Resource Management (AF-MRM) and is now widely used in the U.S. Air Force. The Rail Safety Regulators Panel of Australia has adapted CRM to rail as Rail Resource Management and developed
903-608: The TEM. Training for LOSA experts includes two sessions: education in procedural protocols, and TEM concepts and classifications. A LOSA trainee is taught to find data first and then code them later for both sessions, during which a crew member must exhibit "LOSA Etiquette" — ability to notify the pilot as to why he or she was not able to detect an error or threat after a flight. The pilot's responsibilities include his or her opinions on what safety issues could have had an adverse impact on their operations. A LOSA trainee must then record

According to Popular Mechanics , which examined
1032-404: The attendant sub-disciplines which each of these areas entails. CRM can be defined as a system that uses resources to promote safety within the workplace. CRM is concerned with the cognitive and interpersonal skills needed to manage resources within an organized system rather than with the technical knowledge and skills required to operate equipment. In this context, cognitive skills are defined as
1075-418: The cockpit conversation just before the crash: The men are utterly failing to engage in an important process known as crew resource management, or CRM. They are failing, essentially, to cooperate. It is not clear to either one of them who is responsible for what, and who is doing what. The Canadian Transportation Safety Board (CTSB) determined a failure of Crew Resource Management was largely responsible for

Up until 1980, we kind of worked on the concept that the captain was THE authority on the aircraft. What he said, goes. And we lost a few airplanes because of that. Sometimes the captain isn't as smart as we thought he was. And we would listen to him, and do what he said, and we wouldn't know what he's talking about. And we had 103 years of flying experience there in

It is a guideline that communicates in detail what
1419-701: The importance of operational procedures and technical knowledge, with less emphasis placed on nontechnical skills, which became isolated from the real-world operational contexts. Safety training, including TEM, is important because a crew's nontechnical (safety) knowledge helps more in managing errors effectively than crews' familiarization with operations through experience. Candidates who are shortlisted during selection and training processes must demonstrate analytical and coordination capabilities. Possessing these nontechnical skills allows pilots and crew members to carry out their duties efficiently and effectively. The following components are methods that help provide data for
1462-891: The industry-wide CRM training, the FAA issued Advisory Circular 120–72, Maintenance Resource Management Training in September 2000. Following a study of aviation mishaps between 1992 and 2002, the United States Air Force determined close to 18% of its aircraft mishaps were directly attributable to human error in maintenance, which often occurred long before the flight in which the problems were discovered. These "latent errors" include failures to follow published aircraft manuals, lack of assertive communication among maintenance technicians, poor supervision, and improper assembly practices. In 2005, to address these human-error-induced aircraft mishaps, Lt Col Doug Slocum, Chief of Safety at
1505-524: The mental processes used for gaining and maintaining situational awareness, for solving problems and for making decisions. Interpersonal skills are regarded as communications and a range of behavioral activities associated with teamwork. In many operational systems, skill areas often overlap, and are not confined to multi-crew craft or equipment, and relate to single operator equipment or craft. Aviation organizations including major airlines and military aviation have introduced CRM training for crews. CRM training
1548-545: The merits of participative management for captains and assertiveness training for other cockpit crewmembers. (Class II, Priority Action) (X-79-17) Diehl was assigned to investigate this accident and realized it was similar to several other major airline accidents including the crash of Eastern Air Lines Flight 401 and the runway collision between Pan Am and KLM Boeing 747s at Tenerife . Captain Al Haynes , pilot of United Airlines Flight 232 , credits CRM as being one of
1591-540: The pilots to provide another layer of enhanced communication and teamwork. Studies have shown the use of CRM by both work groups reduces communication barriers and problems can be solved more efficiently, leading to increased safety. CRM training concepts have been modified for use in a wide range of activities including air traffic control, ship handling, firefighting, and surgery, in which people must make dangerous, time-critical decisions. The current generic term "crew resource management" (CRM) has been widely adopted but
1634-578: The results were positive. The crew error-trapping rate was significantly increased to 55%, meaning that crews were able to detect about 55% of the errors they caused. A 40% reduction in errors related to checklist performance and a 62% reduction in unstabilized approaches ( tailstrikes , controlled flight into terrain , runway excursions , etc.) were observed. A proper review and management of SCP and LOSA data can prevent further disasters in flight operations. Crew Resource Management Crew resource management or cockpit resource management ( CRM )
