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 machine are ideally interfaced.
The latter point involves an in-depth analysis

Several safety violations were observed because of this, none of which were fatal (Fitts, 20-21). Shortly after World War II, aircraft cockpits were standardized to the ‘ six-pack' configuration. This was a collection of the six critical flight instruments arranged in two rows of three directly in front of the pilot. In clockwise order from the upper left, they were the airspeed indicator, artificial horizon, altimeter, turn coordinator, heading indicator and vertical speed indicator. This arrangement of instruments provided easy transition training for pilots going from one aircraft to another. In addition, instrument scanning was enhanced, because the instruments were strategically placed so the pilot could reference each instrument against the artificial horizon in a hub and spoke method (Fitts, 26-30). Since then, the bulk of human interfacing with cockpit development has been largely due to technological achievements. The dramatic increase in the complexity of aircraft after the dawn of the jet age brought with it a greater need than ever for automation that exceeded a simple autopilot. Human factors studies in other industries, and within the military paved the way for some of the most recent technological innovations such as the glass cockpit, Heads Up
Display (HUD), and other advanced panel displays. Although these systems are on the cutting edge of technology, they too are
Airplanes are massive and very complex pieces of machinery, and they help us get to places more efficiently and cheaper than traditional ways. Although we have seen that if
Cessna’s Engineering and design feature shows that their aeronautical engineers have imagined hundreds of original aircraft concepts into clean sheet designs advancing to the latest computer-enhanced technology and flight-simulation tools and, finally, to prototype.
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
Since the beginning of aviation, aircraft have been used for other intentions besides carrying passengers and cargo. They have been used as weapons of war dating all the way back to the first world war, and the use of aircraft has enlightened the advancement of the aviation. “Throughout the history of aviation, the greatest progress in flight has been made during time when either war or the threat of war was present” (Millspaugh, et al., 2008, p. 33). However, the war we face today has been triggered by the deliberate use of aircraft to cause death, destruction, and mayhem.
During World War II, the aircraft manufacturing industry took-off. According to Dr. Bright (1978), “by the year 1944 it was the largest industry in America” (p. 1). It soon declined in the years following due to material flaws, lack in engine performance, and production manufacturing methods.
Technological developments have both created new opportunities as well as threats for the aviation industry.
There are many aircraft accident factors in which investigators need to pursue in order to come to a good conclusion on what the cause or causes of an aircraft accident were. A portion of what the investigator looks into is the human factors surrounding the accident. This highly diverse and expansive area needs to be systematically looked into to figure out if any human factors were causation of an aircraft accident. One model that investigators utilize in order to sift through the human factors that may be attributable to an accident is the Human Factors Analysis and Classification System (HFACS) Model. This Model breaks down human factors into four different sections, organizational influences, unsafe supervision, preconditions for unsafe acts, and unsafe acts of operators. Throughout this case study, the accident of American Airlines flight 1420 will be dissected utilizing the HFACS Model to uncover human factors issues with the aircraft operator organization, aircraft flight crew, and the Federal Aviation Administration (FAA).
As a collaborative case study, we analyzed the American Airlines Flight 1420 accident using the SHELL Model. The SHEL Model was developed by a Professor Elwyn Edwards in 1972 and it was later modified to the SHELL Model by a human factors consultant named Frank Hawkins. We can see all the human factors that were involved in the accident utilizing following aspects software, hardware, environment, liveware and liveware. The National Transportation Safety Board (NTSB) conducted a thorough investigation and determine that the American Airlines Flight 1420 was a runway overrun accident caused by human factors.
Towards the end of the War the airplane becomes a practical device of war being able to carry weapons. Anthony Fokker and Louis Bleriot create the most successful of early modern biplanes known as the D-VII and D-VIII. Biplanes are eventually taken over by the monoplane, or one wing. This new design allowed for faster flight and better visibility for the pilot. Air-cooled engines lead the way for commercial aircraft, and Boeing introduces the first modern airliner the 247. Airplanes are effected the greatest by supply and demand of war. New styles of war begun to emerge so did new and improved types of aircraft. The population of the U.S. also begun to grow which leads to the modern most sophisticated commercial airliner the 777. Most aircraft improvements are found in the military and intelligence field. The most high tech aircraft known today for such things as spying are the SR-71 Blackbird, and the U-2 Spy plane. The most complicated and best aircraft performance is still held by the space shuttle and probably always will be. The last 200 years have seen incredible changes in aircraft from the man with wings to heavier than air flying machines that can travel at supersonic speeds.
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 advancement within fighter planes has had an enormous impact on society. Prior to the fighter plane, when in war army troops would be confused where the enemy is based and what they are doing. This was because they never thought flying was achievable so this was not thought about majorly. Fighter planes today are utilized even more than they were 102 years ago… There is now the inclusion of faster engines, higher altitudes, weaponry attached, and the ability to hold more cargo. Fighter planes have had an effect on the growth of people interested in aviation in the army. This therefore is creating jobs for the future and making society better as more people are involved in this workplace. The demand of fighter planes has increased as in
1.) In early 2003, Boeing announced plans to design and sell an airliner named the 7E7. Boeing aimed for the 7E7 to be more fuel efficient, carry between 200 and 250 passengers, able to accomplish both domestic and international flights, as well as be 10% cheaper to operate than Airbus’s A330-200 aircraft. All of these attributes were attractive to Boeing but would come at significant costs. To accomplish these attributes, Boeing proposed to construct the aircraft
Employees will feels stress and decrease in the performance when handle a lots of job tasks which seem unlikely to finish. Job enlargement also lead to decrease in social interaction and increase in work load therefore decrease motivation, job satisfaction and commitment of the employees (Donaldson, 1975). For instance, it will influence decision making process and dangers the entire flying process if pilots feel stressed and fatigue when facing too much of job
It 's very easy to fall sick these days especially when you 're traveling and you should try and find out as much as possible about how you can prevent this from happening to you. Naturally, it 's quite scary to contemplate some of the stories that we 've come across in the New England journal in the recent past, about airline passengers who have passed on some really worrisome diseases to others who are travelling with them. The cabin of an airplane is a closed space and in this environment there 's a lot of chance for germs to multiply and spread. Some are even potentially hazardous like E_coli, salmo-nella, coli-form, rota-virus. Even the common cold is not exempt as well as MRSA, which is very well known form of staph. You might think that these germs can be contracted from any place that has lots of people passing through, but the fact is that busier a place is, the more likely it is to have plenty of germs. But then, we can 't possibly keep ourselves away from these places where germs breed so easily because for practical purposes we need to travel and even go to places that have heavy crowds like shops and movie halls. So what can you do to prevent picking up these germs if you simply have to travel or visit these places? Experts give a few pointers below on how to stay away from the germs and stay healthy. Sitting at the front of the plane. "Try and get a seat near the front, because there 's better air flow from the ventilation systems here," advises
Planes have shifted from wood and canvas structures to ones made from aluminum and other composite materials. Propeller driven planes are still around today but the engine used to spin the propeller has become more efficient and powerful. Jet engines have replaced many of the propeller driven engines on the bigger planes allowing the plane to fly faster and at greater altitudes. The incorporation of avionic systems like auto pilot, navigation, and communication has made the pilot's life easier when flying. Without these advances in the airplane people and/or goods wouldn’t able to fly the great distances they do today. The airplane is used all over the world for varying reasons, commercial airline companies such as United, Delta, and Southwest fly passengers all over the world for business or leisure. Companies like UPS, Fedex, and the United State Postal Service use planes to deliver packages all over the world. The military uses planes in time of war, for reconnaissance missions, and to deliver aid to countries in times of need. Emergency services use planes to transport injured people to different locations or put out wildfires from the sky. Those are just a few examples of how improvements to the airplane has made an impact on citizens that surround
