Human factors cause of different types of Aircraft Accidents
The study also compares the human factors that cause different type of aircraft accidents. As being in fig 1 and 2, the situation awareness is the most contributing factor to that cause aircraft accidents for both the B737 Classic and B747 aircraft. However, the B737 Classic provides Mean =130 value for the situation awareness, while B747 records Mean =70 for the situation awareness. The communication break is another most contributing human factor that causes aircraft accidents. However, the Mean value for B737 is 90, while the Mean value of B747 is 55. Although, B747 is bigger than B377 Classic, however, the human factors affecting the bigger aircraft are more pronounced than the human factors affecting the smaller aircraft.
However, A320 Family is a slim aircraft. As being revealed in the fig 3, the human factors causing the aircraft accidents for the A320 Family are higher than the human factors for both B747 and B737. The situation awareness for the A320 Family is 340 while the communication breakdown is 240.

Correlating factors between types of anomalies and Aircraft Type
The paper also investigates the anomalies and the aircraft type. The paper uses the factors below as the types of anomalies that can cause aircraft accidents:
Aircraft Equipment Problem
ATC Issues
Conflict
Deviation Altitude
Deviation Procedural
In-flight Event
As being revealed in Fig 4, 5, 6, 7, 8 and 9, the 999, A320 Family aircraft and B737NG are the most vulnerable to anomalies out of all the aircrafts evaluated.

Conclusion
The aircraft incidents that lead to the constant loss of life has been the major concern to government and pople globally. When an aircraft accidents occurs, the...
Aviation & Human Factor Aviation "The history of the development and progress of Human Factors in aviation, highlighting areas of significant change" Development in Aviation field is an essential element from defense prospective of any country. Advancement in assembly of an aircraft is always a result of some human error in handling. Error handling while pilot is operating an aircraft is an unrecoverable action in some cases. Human handling for safety of aircraft,
Human Factors in Aviation Safety The human beings with their immense capabilities, imagination, creativity, and cleverness have transformed the world into an industrial world that is surrounded by numerous inventions, innovations, and advancements in various facets of life. Aviation industry is also one of the developments of the human beings, which was imagined as an attempt to emulate bird flight. Human beings were engaged in this phenomenon for centuries prior to

They just assume that the autopilot will take care of flying the plane, and their skills get rusty with lack of use. Then, if something goes wrong with the autopilot system the pilot and his or her crew members may not know what to do and they may not react as quickly as they need to in order to protect the passengers and the rest of the crew members
The mechanic must have adequate knowledge, training, data for assigned task, tools and equipment, be mentally and physically prepared, take safety precautions, have adequate resources, and have researched FAR, Federal Aviation Regulations, to ensure compliance.

Human Factors in Aviation Brief Historical Background The Airline Industry has a history that dates back to 1903 when the Wright brothers made their first successful flight in Kitty Hawk, North Carolina. Initially the public did not take the idea of the airplane travel favorably. But this event marked the beginning of the Airline Industry as more and more inputs were given by people such as Charles Lindbergh who successfully completed a
