PEAR Model – Aviation Maintenance

The PEAR model recognizes four things: 1. The people who do the job 2. The type of environment in which they work 3. The actions that are taken 4. The recourses necessary to complete the job
People:
Most human factors programs are centered around people. They are the least reliable. However, they are necessary. There are four issues when considering the people in human factors. * Physical – physical size, age, strength, and sex. * Psychological – workload, experience, attitude, and emotional state. * Physiological – health, fatigue, lifestyle, and hunger * Psychosocial – interpersonal relations (people skills)
Environment:
There are two main locations in aviation maintenance – the ramp, hangar/shop and the relationship environment with the rest of the company. The first one can have issues with noise level, temperature, and other physical problems. The organizational factors with the rest of the company, however, has to do with communication, mutual respect, and cooperation.
Actions:
Human factors programs analyze the actions of individuals and the reasons they make the decisions that they do. Job Task Analysis (JTA) is used to determine what resources, instruction, and tools are needed to perform a task, as well as a person’s skill level and attitude.
Resources:
There are physical and non-physical kinds of resources. The physical types include things like tools, computers, test equipment, and manuals. The non-physical resources include time allotted for work, number and qualifications of workers, communication between everyone in the company.

Aviation Human Factors

...Running Head : Aviation Aerospace Human Factors in Aviation Aerospace Some of the greatest challenges in the operation and design of large machine systems such as aviation vehicles and aerospace vessels, arise from human factors . It is from such challenges that human-factor engineering has emerged, determined to optimize the interaction between man and machines for the purposes of safety and efficiency. As such, human-factors engineering concerns itself with operating procedures and the training of personnel , as well as issues of interface design (Britannica , 2008 ). These are crucial issues to aviation and aerospace, as human error has been identified as a primary contributor to more than 70 percent of commercial airplane hull-loss accidents. Graeber (1999) asserts that human error is a major concern within the areas of not only flight operations but in maintenance and traffic management as well. To remedy these matters, human factors engineering must identify the limits and characteristics of cognition , information processing and memory and how they can most effectively be integrated into the day to day operations of aviation and aerospace. This means going beyond mere personnel training and redundant safety protocols, but making knowledgeable and flexible observations about how humans interface with aviation and aerospace technology. Because technology tends to evolve faster than our ability to predict how humans interact with it, the overseers of aviation......

Human Factors

...Human Factors in Aviation Safety Final Paper Curtis D. Hudson Embry-Riddle Aeronautical University Human factors in aviation isn’t a new concept but at the time when the Hubble telescope, and stealth bombers were still fresh ideas, Human factors was just now hitting its stride. In 1988, Earl Weiner and David Nagel coincidently released a book titled Human Factors in Aviation (Salas, Maurino and Curtis). During this time, HF was still being slowly accepted and established as a practice to help increase the awareness and improve aviation safety. This period is also significant because prior to then, Human Factors researchers were not involved with aviation system designs and were normally included upon design completion. The incorporation of having HF researchers involved in the design process helped the role evolve and expand the field research. As students of HF research we are aware of the importance of the technology and design of the cockpit, crew resource management (CRM), health and judgment of the crew and how automation plays a role in aviation. This was also a somewhat foreign practice in the beginning. Human Factors researchers were limited to the cockpit and overall cabin technology design. It can be argued that Human Factors in Aviation played a big role in the way business is conducted now compared to before this book was written. When we hear of an aviation mishap, particularly a plane crash, the first thing that comes...

Dirty Dozen of Human Factors

...The Dirty Dozen The company I work for is very big on human factors, as we all have to go through training for it when we first get hired on.  And one specific part of human factors they focus on is the aviation "Dirty Dozen".  I bring this up because it is a large part of what the Safety Management System (SMS) uses when investigating an aircraft maintenance damage incident.  The aviation Dirty Dozen are: fatigue, stress, complacency, communication, awareness, distraction, lack of knowledge, teamwork, lack of resources, pressure, lack of assertiveness, and norms (The Dirty Dozen, n.d.).  I have been involved in an incident (or two) myself, and when I talked to the SMS investigator, they literally went down the list of the Dirty Dozen and asked me if I had any issues with any of the conditions.  They understand that the employees are human, and are prone to conditions that cause mistakes.  I'm not saying that the Dirty Dozen is a fail-safe excuse for an incident, but it gives the investigator the human factor condition(s) that might have played a role, instead of just blaming the employee for the aircraft incident.  This allows the investigator to make a fully informed decision on what the proper course of action is following the incident.  I have seen thousands of dollars in aircraft damage and good mechanics be reprimanded from verbally to termination.

Human Factors Analysis and Classification System

...Human Factors Analysis and Classification System Abstract As aircrafts become more reliable over the years, humans have progressively become more of a causal factor in aviation accidents. Thus, being able to analyze an accident from a human factor perspective is of paramount importance. However, a proper framework of accident analysis is necessary to address the complex and often nebulous nature of human error. The Human Factors Analysis and Classification System Maintenance Extension (HFACS-ME) is one such framework that serves as an accident investigation and data analysis tool. This article will analyze how HFACS-ME is used from an applied perspective and demonstrate its utility using case studies. Human Factors Analysis and Classification System Maintenance Extension The Human Factors Analysis & Classification System (HFACS) was originally developed to analyze and classify human errors and other factors contributing to aviation incidents. HFACS combines features from Heinrich’s “Domino Theory” and Edward’s “SHEL Model” as well as Reason’s model to uncover factors that contribute to accidents (Schmidt, J. Lawson, D., n.d.). The Maintenance Extension of HFACS termed HFACE-ME was created to address aviation maintenance related incidents and facilitates the recognition of defective or absent defenses at four levels namely, Unsafe: Management Conditions, Maintainer Conditions, Working Conditions, and......

Human Factors in Aviation Maintenance Dirty Dozen

...Dirty Dozen Twelve of the most common human factors that are related to aircraft accidents or incidents are called the Dirty Dozen. These factors have been identified to affect people and make them to make the poor decisions. The concept of the Dirty Dozen was created in 1993 by Gordon Dupont, he was working for Transport Canada during this time, while he was creating a training program on human factors in aviation. It is now recognized as the foundation of the aviation industries human factor in aviation maintenance. (Adams, 2009) Lack of communication This is one of the more important parts of the Dirty Dozen. Communications are a two way street that has to do with the person who is giving the communications to the person receiving the communications. During verbal instruction it is common the as little as 30% of a message is received. It is safe practice to keep important messages written down so there is not a lack of communications. Some maintenance outfits use log books so that other shifts can refer back to what was done and by who. Verbal messages need to be relatively short with key things being emphasized on. As a person that is getting instructions it is very important no to assume anything and to have things clarified. (Adams, 2009) Distraction Distractions are anything that can take the attention of a person during a task. There are distraction during work that cannot be removed and heave to be worked with. Noises are a......

In common with most other complex technical activities, human error is implicated in the majority of aviation-maintenance-related quality lapses, incidents, and accidents. General estimates of this human error contribution have increased over the years, from a low of around 20% in the 1960s to values in excess of 80% in the 1990s. Human error in aviation is somewhat of a sensitive topic due to the recent tragic events of September 11, 2001. The goal of this research is to understand human error in aviation, in order to understand how designing better computer systems can assist in making the aviation industry safer for pilots and passengers, by reducing human error. This paper does not attempt to address accidents caused by......

Human Factors

...Stress There are many types of stress. Typically in the aviation environment there are two distinct types - acute and chronic. Acute stress arises from real-time demands placed on our senses, mental processing and physical body; such as dealing with an emergency, or working under time pressure with inadequate resources. Chronic stress is accumulated and results from long-term demands placed on the physiology by life’s demands, such as family relations, finances, illness, bereavement, divorce, or even winning the lottery. When we suffer stress from these persistent and long-term life events, it can mean our threshold of reaction to demands and pressure at work can be lowered. Thus at work, we may overreact inappropriately, too often and too easily. The situation of stress arising from lack of stimulation at work has been covered above under Complacency above. Some early visible signs of stress include changes in personality and moods, errors of judgement, lack of concentration and poor memory. Individuals may notice difficulty in sleeping and an increase in fatigue, as well as digestive problems. Longer-term signs of stress include susceptibility to infections, increased use of stimulants and self-medication, absence from work, illness and depression. It is important to recognise the early signs of stress and to determine whether it is acute or chronic. Coping with daily demands at work can be achieved with simple breathing and relaxation techniques. However, perhaps more......

Human Error in Aviation

...Human Error in AviationMatthew R. GriffithEmbry-Riddle Aeronautics university AbstractIt is unreasonable to assume that any person could operate continuously without ever making a mistake. Thus, human error is a very real and inevitable problem in the aviation industry. Unfortunately, for those involved, it is usually met with disastrous results. One momentary lapse of judgment might very well result in a large numbers of fatalities, as well as, hundreds of millions of dollars in damages. Human error can be described as any event that takes place because a task, or portion of a task, was not performed with its exact specifications. Human error can stem from a very wide spectrum of circumstances. Three critical areas of concern that will be carefully reviewed in this paper are the following: fatigue, vision, and communication. It is important to study these primary causes of human error and look for trends or break downs that might very well serve to protect the safety of future flights. Only through the management of human error can continue the outstanding reputation of safety in the world of aviation. Human Error in AviationBefore an accurate discussion on the root causes of human error can take place, it is necessary to understand the fast pace setting of the aviation industry. One visit to any major airport, such as Atlanta's international airport, and one will come to appreciate the tremendous demands placed upon all the aviation professionals involved......

Human Factors Analysis

...Human Factors Analysis The Colgan Air 3407 accident, was a commercial flight that crashed in Clarence Center, New York on the way to Buffalo, New York. The flight crash was due to poor piloting and background conditions that have changed regulations in the aviation industry. In this essay we will cover this accident using the PEAR model to evaluate the accident. The first aspect we will evaluate of the accident is the people element of PEAR. The people element covers anyone involved or responsible for the accident as well as the factors affecting them. In the accident it was deemed that the captain was responsible for the accident, as the captain didn’t respond properly to the stick shaker which is an indicator that the plane could stall, his failure to monitor the plane's airspeed, as well I think it was the fault of the airline company and how they managed everything. Some of the other factors of the people part of pear is how they treated their pilots, overworking them, making them travel long distances from home which made adequate rest difficult, and just and overall difficult work environment. The next aspect of PEAR is environment, which deals with environmental considerations such as weather, lighting, other personnel and many other factors. In the Colgan air accident environment played the role with the weather conditions primarily. Before the crash the weather caused icing on the plane, and when this was combined with fatigued pilots, one being sick, as......

Economic Factors and the Aviation Industry

...Using real world examples, illustrate how the significance of economic factors can be seen to have influenced firms’ conduct and/or financial performance. Apply and reflect on economic ideas and theories. Demonstrate some specific examples of how economics can help us to understand the behaviour or well-being of firms as well as, if you wish, the limitation of economics. So that to end, you are being assessed less on coverage but more on application. How Economic Factors Affect the Aviation Industry Introduction The aviation industry is particularly susceptible to external economic factors because it affects and depends on a substantial number of industries. Also, because the industry involves operating between borders, then economic factors from other parts of the world other than the domestic market also affect it. Issues such as fiscal policies (both within and without the countries of destination), wage inequality and positive and negative externalities have a way of changing operations within this industry. How shifts and price elasticity of supply and demand affect the aviation industry Supply and demand price elasticity of airline carriers may vary depending on the nature of the industry. For new and emerging industries such as the Indian aviation sector, then price elasticity of demand and supply is near perfect. The number of transporters being added into their markets are largely affected by the nature of demand for the commodity the country underwent......

Five Factor Model

...Psychology 204 November 6th , 2015 Five Factor Model Paper According to my results from the Five Factor Model test I completed I am a kind and trusting person who has a wild imagination, who often feels anxious and or irritated. My highest scores were in agreeableness, and openness to experiences. According to my text book people who score high in the agreeableness category tend to be “sociable and easy to get along with, and those who score high under openness to experiences are intellectually curious, and untraditional” (Lilienfeld, 2011). My lowest scores were in emotional stability and extraversion, scoring low in these categories means that I am likely to be anxious, irritated, and shy. I believe that the results are consistent with how I see myself. I have come to accept that I am a sensitive person who feels shy and closed off when trying to integrate with a new group, especially big groups. Although I am shy in big groups I do well in dyads, I feel less anxious in small groups, and many people have said that they enjoy confiding in me because they find me easy to talk to. Personality is complex and it varies between each person because our personalities have many dimensions and layer, but I think that this personality test kind of covers all the bases. When I compare my results to the table of Portland State University college student norms I see that my means tend to stay mostly moderate compared to the norms. My scores placed moderate for extraversion,......

Human Factors

...HFACS Written Project By Todd Ross Embry Riddle Aeronautical University Abstract American Airlines flight 1420, a McDonnell Douglas MD-82, Crashed at the end of runway 4R at Little Rock Airport in Little Rock, Arkansas. Human Factors (HFACS) play a major role as flight crew decision making abilities were evident. A few human factors played into this accident and as a post accident investigation concluded, this accident could have been prevented is the right pre-causations were done. Options were provided to weather cancel, or divert into other areas that had better weather. Inclement weather conditions were the external factor that played a major role in this accident, however weather can be avoided in most cases. Other aspects that were avoidable errors made by humans were pilot fatigue and the confusion to the ground emergency personnel that cause a response time delay. Executive Summary Flying under 14 Code of Federal Regulations Part 121 on an instrument flight rule, American Airlines flight 1420, a McDonnell Douglas MD-82, N215AA, crashed as it lost control on landing causing the aircraft to overrun the end of runway 4R. Flight 1420 departed Dallas/Fortworth approximately 2240 with 2 flightcrew members, 4 flight attendants and 139 passengers. According to the NTSB, the determined that the probable cause of this accident were the flight crew failures to discontinue the approach with......
