The Human Factors Analysis and Classification System (HFACS) identifies the human causes of an accident and offers tools for analysis as a way to plan preventive training. [1]
Mental health in aviation is a major concern among airlines, regulators, and passengers. This topic gained more attention after the 2015 Germanwings crash, which was deliberately caused by the plane's copilot. Little data exists on mental health in aviation, but steps to gather relevant information and provide better solutions are underway.
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 the considerable development of electronic aids since then ...
Physiological stress is a physical change due to influence of fatigue, anxiety, hunger, or any factors that may change a pilot's biological rhythms. [16] Lastly, psychological factors include personal issues, including experiences, mental health, relationships and any other emotional issues a pilot may face. [16]
If this is the case, a contributing factor may be disharmony between the respective systems/routines and human nature or propensities. The routines or systems can then be analyzed, potential problems identified, and amendments made if necessary, in order to prevent future errors, incidents or accidents from occurring.
Human factors are the primary causal factor aviation accidents. [12] In 1999, the National Aeronautics and Space Administration, NASA, testified before the U.S. House of Representatives that pilot fatigue impacts aviation safety with "unknown magnitude". The report cited evidence of fatigue issues in areas including aviation operations ...
Both of these are inevitable human factors encountered in the commercial aviation industry. The use of checklists in emergency situations also contributes to troubleshooting and reverse examining the chain of events which may have led to the particular incident or crash.
A Federal Aviation Administration (FAA) study of 55 human-factor aviation accidents from 1978 to 1999 concluded that number accidents increased proportionally to the amount of time the captain had been on duty. [7] The accident proportion relative to exposure proportion rose from 0.79 (1–3 hours on duty) to 5.62 ( more than 13 hours on duty).
