AERO2347 Using the PEAR Model Assessment Answer

Description of the Model along with Limitations as well as Effectiveness

The PEAR model is recognized as a simple as well as effective model that is utilized to identify human factors issues across aviation accidents. It entails solitarily of three rudimentary components such as people, environment, and aircraft. These components are intricately analysed in terms of their contribution to the accident and their interactions with each other. The people component of the PEAR model revolves around precisely on the human factors pertaining to the flight crew along with other personnel who are duly involved in the flight. This generally encompass their training along with respective work experience, workload, and the flow of communication. By meticulously analysing the role of human factors in the accident, the model simply intends to identify and illustrate the underlying reasons of errors made by the flight crew or other personnel. Followed by that, the environment facet of the PEAR model concentrates solely upon on the physical as well as the operational aspects that are coherent to the aviation ambiance. This inculcates factors such as conditions of the weather followed by air traffic control, apart from airport facilities. The environmental factors broaden the mental horizon of managerial authority of the aviation industry which the model seeks to determine any external factors that may have contributed to the accident. Finally, the aircraft component of the PEAR model emphasizes on the technical aspects of the aircraft, such as its apparatus, design of the aircraft, maintenance requirement, and similar facets. The reason being that by evaluating the aircraft-related factors, the model can seamlessly identify any relevant technical issues that have contributed to the accident.

On the contrary, one of the fundamental shortcomings associated with the PEAR model is its simplicity. The model is designed in such a manner that it can furnish a high-level overview of human factors issues, and delineates crucial reason of accidents, which may otherwise be challenging to completely gain cognizance due to its inherent complexities. Moreover, the model does not account for organizational or systemic factors that may contribute to accidents.

Determining the Human Factors issues Pertaining to the Aviation Accidents

After meticulously analyzing the aforementioned human factor model, an inference can be drawn that for simpler accidents, the efficiency of the PEAR model stands atop. To put it in simple perspective, it can be stated that if the accident revolves around malfunctioning of aileron or alignment impediment in radar, then the feasibility of its resolution to emanate effectively from the PEAR model is substantially high in comparison to SHELL or HFACS model (Nkosi, 2020). Despite its simplicity, the PEAR model has proven to be a valuable tool in situations where limited resources and time are available. This model serves as a useful springboard for identifying the fundamental causes of human error by analyzing the intricate relationships between individuals, surroundings, and aircraft. The application of the PEAR model enables investigators to promptly determine the primary factors that led to the accident and ascertain whether further in-depth analysis is necessary.
