A Technical Analysis of Ergonomics and Human Factors in Modern Flight Deck Design
I. Introduction Since the dawn of the aviation era, cockpit design has become increasingly complicated owing to the advent of new technologies enabling aircraft to fly farther and faster more efficiently than ever before. With greater workloads imposed on pilots as fleets modernize, the reality of he or she exceeding the workload limit has become manifest. Because of the unpredictable nature of man, this problem is impossible to eliminate completely.
However, the instances of occurrence can be drastically reduced by examining the nature of man, how he operates in the cockpit, and what must be done by engineers to design a system in which man and

III. System Design A design team should support the concept that the pilot's interface with the system, including task needs, decision needs, feedback requirements, and responsibilities, must be primary considerations for defining the system's functions and logic, as opposed to the system concept coming first and the user interface coming later, after the system's functionality is fully defined.
There are numerous examples where application of human-centered design principles and processes could be better applied to improve the design process and final product. Although manufacturers utilize human factors specialists to varying degrees, they are typically brought into the design effort in limited roles or late in the process, after the operational and functional requirements have been defined (Sanders & McCormick, 727-8). When joining the design process late, the ability of the human factors specialist to influence the final design and facilitate incorporation of human-centered design principles is severely compromised. Human factors should be considered on par with other disciplines involved in the design process. The design process can be seen as a six-step process; determining the objectives and performance specifications, defining the system, basic system design, interface design, facilitator design, and testing and evaluation of the system. This model
Nicholas Carr, the author of “All Can be Lost: The Risk of Putting Our Knowledge in the Heads of Machines”, expresses the major concerns towards technology. In this story many crashes and devastating accidents are presented. These accidents could have easily been avoided through the proper knowledge of the air staff members. As a result of technology, pilots are trained less expensively and therefore are unable to react in urgent situations. For example, they now rely on auto-pilot to do more of the directing than they rely on themselves for. This idea is expressed throughout many other stories, demonstrating the lack of knowledge due to the increasing use of technology. One main point that Carr makes is that individuals are constantly starting
Throughout the Fate is The Hunter and The Right Stuff the pilots have been thrown in and put their selves in great danger while flying. These risks that the pilots must face have been approached in very different ways in some aspects, and almost identical in others. Each of the books contain pilots who make decisions based on their judgments alone and without any or much background information on it. Weather is another risk that the pilots need to overcome and each book has a different approach to it_________. Another difference between the two types of flying are their attitudes towards their flight, with military having huge egos and commercial having a more modest and safer approach. ____?_____.
Markham’s depiction of a pilot’s relationship to his/her instruments portrays the sense of pride that one feels towards his/her passion in life. As Tom teaches Beryl how to fly, he explains that “[i]f you can’t fly without looking at you airspeed and you altimeter and your back-and-turn indicator you can’t fly” (Markham186). Additionally, Tom compares one who must rely on these tools to “somebody who only knows what they think after reading his newspaper” (186). Tom’s explanation of the use of instruments illustrates his years of experience as a pilot. As a result of his numerous flights throughout the world, Tom has developed confidence in his ability to fly. Additionally, Tom is certain that Markham will also acquire the same certainty in her “speed sense, sense of height, and sense of error” (187) as she gains experience. As the passage continues, the reader begins to sense the pride that Tom maintains towards his
To be an airline pilot is most of the time described in terms of duties, job requirements, proficiency, training, employment opportunity, and good salary. These features picture a plain profile that fit into the specification of just an ordinary career. However, an aviation career comes with many challenges than expected. When focusing on statistics about being a pilot, it indicates a lifestyle that many inspire to work despite the many challenges that face this career. The challenges that pilot face revolve around being rested during long flights, performing unexpected, simultaneous tasks, and passing the medical examination in order to remain qualified. When combined with fatigue due to long flight hours, these different aspects can
“Please know I am quite aware of the hazards. I want to do it because I want to do it. Women must try to do things as men have tried. When they fail their failure must be but a challenge to others.”- Amelia Earhart. Learning about the things Zits went through was hard. He did not have a dad. His dad walked out on him when he was born. He never had a father figure to look up to and learn from.
If you have a love for the sky and aviation is one of your interests, you're not deterred from being in charge of at times more than 100 lives, and you have a soft spot for exploring the world than becoming an airline pilot is for you. Airline pilots have one of the coolest, most exciting nerve racking jobs out there. My goal for this paper is to explain all about how to become an airline pilot, what it takes to become one, the facts about the job, and some pros and cons of being in the field. My interest in flying was harbored as a child during vacations, my mother is a flight attendant so we traveled often. Whenever entering an airplane I was at awe of the sheer number of controls in the cockpit and the
The purpose of this study is to examine the performance of pilots flying multiple types of aircraft in an experimental setting. Pilot performance will be assessed by written tests and simulator sessions. This study will build on a previous field study, Pilots Flying Multiple Aircraft Types or Multiple Flightdeck Layouts, which was conducted for AVS 4504 Aviation Safety Analysis. The results of that study showed a need for a simulator study to further identify if pilots have issues maintaining currency in multiple types of aircraft.
The task at hand is to analyse a human-machine system. Topics such as; visual sensory systems, auditory, tactile and vestibular systems, cognition, decision making, displays and controls, and anthropometry and workspace design will be explored. The aim of this project is to show understanding of human factors by applying them to a human-machine system.
The science of human factors in aviation has a come along way since the days of the Wright brothers in 1913 but it did not actually start with them. According to Dr. Bill Johnson, Chief Scientist at the Federal Aviation Administration, human factors “dates back to the 1600s when Leonardo da Vinci drew the Vitruvian Man, with all the anthropometric measures, [when] he was trying to decide if a human was strong enough to propel an aircraft” (FAA, 2012). Long after the work of da Vinci, human factors has brought advancements to aircraft design while creating a greater understanding of the human role in mishaps.
The theories of ergonomics, underlying principles and design methods put forward assistance to optimize human well-being and overall system performance. Its scientific applications make the working environment most efficient, safe and comfortable. The International Labour Organisation defines Ergonomics as 'the application of the human biological sciences in conjunction with the engineering sciences to the worker and his working environment, so as to obtain maximum satisfaction for the worker which at the same time enhances productivity'. Historically, the employers in the manufacturing sector have been addressing the issues related to improvement in the health and well being of the employees. There are enough statutes to protect and further the health and welfare of employees in this segment. But, now a days in the service sector also, there is an increasing trend in adopting scientific methods to
The service provided by airline industry is one of a kind, providing distinguished service to its customers. It is a mode of transportation and provides efficient services, with luxury and speed which can’t be replaced by any other industry. We need Porter’s Five Forces analysis to understand this industry as the airline industry is plagued by problems such as varying number of customers, increasing fuel prices, and huge costs clubbed with the ever increasing competition from low cost carriers which provide services for peanuts. Airline industry has a vast expanse of coverage as far as its global reach goes. Porter’s Five Force analysis would also help us delve into reasons for the
Being an airplane pilot is one of the best jobs in today world but also is one of the most stress full jobs. Pilots are always in a case of challenge and this causes a stress. There are more causes and effects of it and this essay would explain it in detail what causes stress? what effects does it have on pilots?.
supervisor is an air traffic tower chief or an air traffic tower shift leader overseeing the operations in the tower. As an air traffic controller on position gets their weather information from a computer, a supervisor may notice that the weather report is not consistent with tower visibility and decide to change the weather being reported by the automated system. Another example of a supervisor is a pilot flying and aircraft on autopilot. The pilot in command of an aircraft is directly responsible for, and is the final authority as to, the operation of that aircraft (FAA, 2014). In the event that an error occurs during autopilot, the pilot is required to take over the controls and fix the problem. Human performance under supervisory control is often poor because of the limited task load placed on operators under normal conditions (Endsley, 1995). Due to reduced control involvement of the pilot, the consequences can be a loss of situational awareness and a decay of direct control skills, which are critical for any midair recovery. Figure 2 below shows how automation can affect situational awareness.
I would like to be a flight attendant because I think working in an environment that continually upholds high levels standard of service as a flight attendant is very challenging the kind of challenge I enjoy.
If we can find the answers to these questions, then I believe it is possible to limit and slow down the number of human errors in aviation, thusly slowing the number of accidents and lives lost due to human performance.
