...Case Analysis Term Paper United Airlines Flight 173 Embry-Riddle Aeronautical University SFTY 320 I. Summary On December 28, 1978, United Airlines flight 173, a McDonnell-Douglas DC-8-61 was a scheduled flight from John F. Kennedy International Airport, New York, to Portland International Airport in Oregon, with an en route stop at Denver, Colorado. When the DC-8 was descending through about 8,000 ft on its way to Portland, the first officer, who was flying the aircraft, requested the wing flaps be extended to 15 degrees, then asked that the landing gear be lowered. As the landing gear extended, an unusual sound was heard and the aircraft yawed. Upon request, Portland approach then vectored the aircraft in a holding pattern southeast of the airport. After about an hour and a half of circling southeast of the airfield while the flight crew coped with the landing gear malfunction and prepared the passengers for a possible emergency landing, the captain finally decided to begin the approach to runway 28L. The plane crashed during the approach about 6 nautical miles southeast of the airport in a wooded populated of suburban Portland due to fuel exhaustion. The aircraft was destroyed and thankfully because there was no fuel in the fuel tanks, there was no fire. Of the 181 passengers and 8 crewmembers aboard, 8 passengers, the flight engineer, and a flight attendant were killed and 21 passengers and 2 crewmembers were seriously injured (National Transportation Safety Board...

...The Colgan Air 3407 crash was a tragedy and reshaped the aviation industry, as we know it today. Everyone on the aircraft including all crewmembers were killed in the crash just outside of Buffalo, New York. The investigation into the crash was very extensive and deemed the crash as pilot error. Using the SHELL model I have determined how certain human factors contributed to the horrific crash. The SHELL model is used to identify what human factors played a role in crashes. SHELL helps us understand the relationship between human factors and the aviation world interact from the aircraft itself to the rules that are followed daily by pilots and airlines. The SHELL model has three different components. The first is Software, which is anything,...

...Human Factors in Maintenance Kevin Carr Embry-Riddle University Nigeria Airways Flight 2120 Nationair DC-8 Flight 2120 took the lives of 247 passengers and 14 crew members; 261 in all; during takeoff on July 11, 1991. The jet was owned by Canadian airline Nolisair, and was being operated by a Nigerian company to transport Nigerian pilgrims in and out of Mecca. The DC- 8 caught fire during take-off from Abdulaziz International Airport, Jeddah, Saudi Arabia. Pilots noticed problems during early stages of take-off and only made it 671 meters in elevation before attempting to turn around for a emergency landing. It was too late; the under inflated tires had overheated began to catch fire. The fire grew and blew out the hydraulics which made the emergency landing impossible. This was the worst wreck a DC-8 had ever experienced and has held the record for many years following. The NTSB concluded that the fire could have been handled by leaving the landing gear extended and away from the plane. Although the pilots failed to make the right decision, and added just one more human error to the equation, it was the obvious neglect by the maintenance team that caused this horrific accident. There are many human factors which played a vital role in the crash. The maintenance team failed to inflate the #2 and #4 main gear tires after recognizing the pressure during the pre-flight. An attempt to inflate the tires failed because there was no nitrogen available at the location. Further...

...Mid Air Collisions Brian Saunders Human Factors David Miller June 18, 2011 Abstract No pilot is immune from a mid air collision and it is one of the pilot’s worst nightmares. Although rare, mid air collisions are a tragic event of when two airplanes collide with each other during flight. Statically speaking, nearly all mid air collisions happen during daylight hours and in Visual flight rules (VFR) conditions and astonishing enough, the greater part of mid air collisions take place within five miles from the airport. The first recorded mid air accident occurred at an air show in the city of Milan, Italy on October 3, 1910. Even though it was a miracle that both pilots survived the accident, mid air collisions would continue to occur without this favorable of an outcome. By the nineteen fifties, and with the introduction of the new generation commercial airplanes, people started to travel more by air than by train; a spur of change was needed. Between the years of nineteen fifty-six and nineteen fifty-eight, two high profile mid air collisions accidents occurred in uncontrolled air space. The accident between a United DC-7 and a TWA Constellation collided and crashed on 30 June 1956 over the Grand Canyon in Arizona killing all one hundred and twenty-eight passengers and crew. The second notable mid air collision was between a United Airlines Douglas DC-7 aircraft with forty-two passengers and two crew and a United States Air Force North American F-100 Super Sabre...

...Crew Resource Management Robert Gibbs Embry Riddle Aeronautical University Abstract CRM, known as Crew Resource Management was once called Cockpit Resource Management. This term got expanded due to the fact that the teamwork of the crew of an aircraft went far beyond just the realm of the cockpit of the aircraft, which basically referred to only the personnel in the cockpit, the pilot, co-pilot, flight engineer, and any other personnel who was stationed in the cockpit area. CRM is very crucial to the safe operation of the aircraft and ground crew personnel. In my opinion, the two crucial aspects of CRM are leadership and communication in the cockpit. There are other important characteristics of CRM as well, such as having a sterile cockpit is very important. So let’s take a look at CRM as we know it. What Is Crew Resource Management? Crew Resource Management—CRM, in layman terms is the teamwork of all aircrew personnel of an aircraft to conduct the safe flight of an aircraft. Now the official definition of CRM is a management system which makes optimum use of all available resources, equipment, procedures, and people- to promote safety and improve the efficiency of flight operations. CRM focuses on interpersonal communications, leadership, and decision making in the cockpit. CRM also focuses on the proper response to threats to safety...

...prescribed medicine order, retrieving information, process information, identification of medication related issues, collaborative planning, decision making, reflection, and etc. These authors are instructors of pharmacy related courses in an Australian University. Their focus in their studies is to research a profession that is not widely studied and to find areas in need of improvement and to resolve them. Most of these authors have also participated in writing the article "Safe dispensing in community pharmacies: applying the software, hardware, environment and liveware (SHELL) model", which focuses on examining common errors made in a pharmacy setting between pharmacists and technology and coming up with solutions to reduce these errors in the future. The experiment showed that there were 50 risk factors when it came to pharmaceutical practices according to the dimensions of the SHELL model, which is a traditional human factors framework. Overall, the audience of these articles are everyone, mainly students, teachers, or other researchers. Students may read these in order to improve their own thought processes and to avoid the common mistakes discussed in the later article. Teachers may use these articles in order to improve their curriculum and to equip students with information to avoid the common mistakes. And researchers may use these information in order to use in their own experiments and to come up with resolutions for existing problems within the pharmacy field. The article...

...Furthermore, this system must include gadgets to support their learning process and not deny it. As the only way to a thorough learning is by setting short term goals and fulfill them with utter success. Setzer, V.W. (1989) In his essay Computers in Education described “We think the school of the future should have human teachers and classrooms, but teachers will have to fight courageously to resist the pressures—by bureaucrats, by commercial interests, by psychologists and by politicians—to turn them into technicians, information repositories, transmitters and facilitators, or that horrible new expression “liveware.” They will have to relate to their students as human beings in development, and not as storing and sorting machines, as real individuals, and not as collective...

...perspective on the computer virus technology. Firstly, viruses are defined, described and classified. Popular anti-virus protection mechanisms are listed. The current impact of viruses is briefly assessed and an attempt is made to isolate and project some expected trends in virus technology. Finally, a number of potential advantages of viruses are discussed. 1. Introduction The computer virus and its technology represent a relatively new phenomenon, although its origins can be traced back to the late fifties. The emergence of the virus technology may be attributed to a combination of factors, including the wide availability of computer resources, the increased level of connectivity, the event of decentralized computing with a certain relaxation of security measures, the development of a hacker community (culture and literacy), and perhaps a general decline in morality principles. All of these factors have resulted in what may be called a democratization of the computer technology. This has in its turn established the necessary "critical mass" for the virus technology to develop. The media have publicized a large number of virus attacks; not necessarily in the most accurate or factual manner. But the very fast evolution of the technology has even confused many professionals. This resulted in a lot of "hype", popular myths and misconceptions about computer viruses. An interesting study claims that "[s]tories about computer viruses may be as full of myth as they are of truth" and...

...Human Factors involved in the crash of ValuJet Flight 592 A Human Factors Case Study Submitted to the Worldwide Campus In Partial Fulfillment of the Requirements of Course SFTY 320 Human Factors in Aviation Safety Embry-Riddle Aeronautical University October 2013 Abstract On May 11, 1996, Flight 592 departed from Miami. It had pushed back from gate after a delay of 1 hour and 4 minutes due to mechanical problems. There were 105 passengers on board, mainly from Florida and Georgia, as well as a crew of two pilots and three flight attendants, bringing the total number of people on board to 110. At 2:04 pm, the DC-9 took off from runway 9L and began a normal climb. 10 minutes later the aircraft crashed into the Florida everglades with all hands on board lost. This Case Study will analyze and evaluate all contributing factors, with focus on the human factors, and propose solutions that would have kept the Liveware element from causing the accident. Intro The crash of ValuJet 592 was an accident that gripped the nation. In a decade of low priced airfare, ValuJet was a house hold name for providing economical flights. The loss of flight 592 raised nationwide concerns over the airline industry; from maintenance practices, to management pitfalls among all of the low cost air carriers. 592’s crash also rocked the entire airline industry, and ultimately caused a loss of confidence by the majority of the public in economical airlines.
