Abstract

Most important thing of the Flight Crew’s role is the Decision Making in aviation.
Flight safety and flight efficiency depend on flight crew’s decision. So Aeronautical Decision Making is more important than other decisions. Aviation decision situations are often complex and a number of factors may influence decision making. Risk and time pressure are situational variables that further constrain the decision process, but flight crew have been trying to do their best. Decision Making causes variable results by the cognitive ability, training for decision making and judgment General decision making tree charts should be described on Flight Operation Manual, but decision in complex situation is made by discussion between flight crew and Operational Control Center. Good Decision Makers have their own decision making model. This study researches how they made decision and flight crew’s decision making model by analysis of a survey.

I. 서론
항공기가 첨단 대형화, 장거리화 되면서 운항 승무원의 역할은 항공기 조종이라는 기본적인 임무에서 운항 전반에 대한 Management 업무로 비중이 옮겨가고 있다. 항공기가 개발된 이 후 많은 항공사고가 발생했으며 초기에는 주로 항공기 자체 결함이나 지원 장비의 결함으로 인한 사고가 많았다. 그러나 첨단 기술의 발달로 인해 항공 사고는 Human Factor에 기인한 사고가 상대적으로 많아졌으며 전체 사고의 약 70%에 이르게 되었다. Boeing사에서 2003년 발표한 자료에 의하면 1993년-2002년까지 발생한 세계 민간항공기 전손 사고는 총198건이며 이중 원인 불명이나 조사 중인 59건을 제외한 총 139건의 약 67%인 93건이 운항 승무원에 의한 사고로 판명되었다(도표-1). 이처럼 항공기 장비나 기상으로 인한 사고보다 인적 요인에 의한 사고 비율이 높아짐에 따라 각 항공사에서는 Human Factor로 인한 사고를 줄이기 위해 다양한 방법으로 접근을 하고 있다. 그 중에서 1980년 초 운항 승무원을 대상으로 시작한 CRM(Cockpit Resource Management)훈련이 대표적일 것이다.

The Imapact of General Aviation

...Air Transportation Management The Impact of General Aviation General aviation is considered one of the three main segments of the aviation market. The other two being commercial aviation and military aviation. General aviation operations are anything other than military and common carriage. Without general aviation, the industry would suffer in countless ways, possibly even collapse. General aviation includes, literally, every other civilian job except for the few related to the airline sector. What I consider the most important ones are aerial firefighting, flight instructing, pipeline patrol, corporate, bush piloting, agricultural, and test piloting. Flight instructing is one of the most important jobs that there is in the aviation industry. It is where pilots obtain the proper training and skills necessary to be safe and adequate. I believe flight instructing is most likely the most underrated and underpaid job in the aviation industry. Without this job, all pilots would have to come from the military, which would cause a severe shortage of pilots. Pipeline patrol requires pilots to fly aircraft at very low altitudes over varying terrain to observe pipelines and check for any problems or vandalism within the lines. Another type of this job is for pilots to patrol the U.S. borders in search for illegal activities. Without either of these general aviation jobs, more resources and man hours would be required to check oil pipelines and secure our borders. Corporate......

Aviation Regulators

...Aviation Regulators Aviation safety is a term encompassing the theory, investigation, and categorization of flight failures, and the prevention of such failures through regulation, education, and training. It can also be applied in the context of campaigns that inform the public as to the safety of air travel. The Federal Aviation Regulations, or FARs, are rules prescribed by the Federal Aviation Administration (FAA) governing all aviation activities in the United States. The FARs are part of Title 14 of the Code of Federal Regulations (CFR). A wide variety of activities are regulated, such as aircraft design and maintenance, typical airline flights, pilot training activities, hot-air ballooning, lighter-than-air aircraft, man-made structure heights, obstruction lighting and marking, and even model rocket launches, model aircraft operation, and kite flying. The rules are designed to promote safe aviation, protecting pilots, flight attendants, passengers and the general public from unnecessary risk. Since 1958, these rules have typically been referred to as "FARs", short for Federal Aviation Regulations. However, another set of regulations (Title 48) is titled "Federal Acquisitions Regulations", and this has led to confusion with the use of the acronym "FAR". Therefore, the FAA began to refer to specific regulations by the term "14 CFR part XX". The FARs are organized into sections, called parts due to their organization within the CFR. Each part deals with a specific type of...

Manaager's Perspective; Aviation Maintenance

...Aviation Maintenance from A Manger’s Perspective Lisa A. Williams Embry Riddle Aeronautical University Management 203 Christopher Urdzik April 26, 2015 Abstract This paper explores aviation maintenance from a Manager’s perspective. There are various governing bodies that control or oversee how maintenance is performed on a routine basis for commercial aircraft. The main governing body that is discussed here is the FAA. Also discussed is the required training of the Airframe and Powerplant mechanic and how management can be assured that mechanics are qualified to release aircraft after performing maintenance certifying these aircraft are safe to fly. Also, in this paper, the attempt is made to show where mechanics need ongoing training to assure management that the mechanic is trained on new technologies that are developed and used in commercial and corporate aviation. The answers are not mapped out by the FAA or training programs so it is up to the company to be sure that the mechanic is made aware of these new technologies through FAA study groups that managers can attend and brief technicians on new developments. Human error cannot be eradicated it is indispensable fact of the human behavior (Maddox, 1998). Although, aviation maintenance managers have acquired high levels of technological skills training related to their profession, the above statement from Dr. Michael Maddox is true in regards to human error.

Aviation and Accidents

...Management Abstract The purpose of this project is to research a few well known accidents and incidents within the aviation history of the United States of America. The project would further describe some of the changes to aviation in our country because of these accidents and incidents. I will be utilizing articles published on the World Wide Web in order to gather the information needed to complete this project. The project will first define the difference between an Aviation accident and an aviation incident. List some well-known occurrences of each and the impact they have had on the aviation community. Accidents in Aviation Sub Topic “An aviation accident is defined in the Convention on International Civil Aviation Annex 13 as an occurrence associated with the operation of an aircraft which takes place between the time any person boards the aircraft with the intention of flight and all such persons have disembarked, in which a person is fatally or seriously injured, the aircraft sustains damage or structural failure or the aircraft is missing or is completely inaccessible.” Wikipidia (2012). Therefore, for an aviation accident to take place according to the Convention on International Civil Aviation Annex 13 two things must be present at least one person and an aircraft. In the same reference an aviation incident is defined as “an occurrence other than an accident, associated with the operation of an aircraft, which......

Aviation Crashes

...8.5 - Term Paper Assignment Submission Historic Air Disasters Richard DeWayne Gwinn Embry-Riddle Aeronautical University Abstract My paper will cover some of the most horrific air disasters in aviation history. I will be using information from the National Transportation Safety Board (NTSB), Federal Aviation Administration (FAA) and news media to draw my conclusion of the events. I will then explain how these air disasters changed aviation, what rules were put in place, what changes to aircraft design were made or what training was needed to prevent a repeat of the incident. I believe this topic is important to the history of aviation in America because we learn from our mistakes and with every aircraft incident new regulations were developed to increase the safety of flight. HISTORIC AIR DISASTERS In this paper, we will be revisiting three airline crashes that changed aviation. 1956 Grand Canyon mid-air collision, 1977 Tenerife Airport Disaster, and 1992 El Al Flight 1862. I believe that these three flights had a significant impact on aviation in terms of safety, design and procedures that are in place today. 1956 Grand Canyon mid-air collision The midair collision between these two airliners led to the birth of the modern air traffic control system. (Fss.aero, 2015) On June 30, 1956 a United Airlines Douglas DC-7 (United Airlines Flight UA 718) struck a Trans World Airlines Lockheed L-1049 Super Constellation (Trans World Airlines Flight TWA 2) over the Grand......

Aviation Safety

...Aviation Safety Abstract Aircraft accidents are not very common, but when they happen, the level of damage is large compared to other means of transport. This is because some aircrafts have a very large capacity of passengers that they can accommodate. This is not always the case, as some of them are small and do not carry so many people. Aircrafts accidents range from fires, collisions, ditching and accidents caused by pilot errors among others. This paper will look at an accident that happened in 1997 at Newark International Airport in New Jersey. The paper will address the causes of the accidents, the findings of the investigation carried out after the accident, recommendations after the investigation as well as the measures taken to make sure that accidents of this type do not happen again. Aviation Safety FedEx Express Flight 14 This scheduled cargo flight was going to Newark International Airport, New Jersey from the Ted Stevens Anchorage International Airport in Anchorage, Alaska. It crashed when trying to make a safe landing on July 31, 1997. The pilots thought that the plane would have little stopping distance after landing, which made them think of landing early on the runway. Misinterpretation of runway data was the main cause of the crash (Dismukes, Berman & Loukopoulos, 2012). The pilots were aware that the plane had problems with its auto-breaks because they failed to initiate during landing, which also contributed to their hasty decision to land......

General Aviation Accidents

...There are three broad classes of aviation that are Military Aviation, Commercial Aviation and General Aviation. This report defines the scope of General Aviation, the type of aircraft flown that operate under it and the FAA Code Of Regulations that govern them which are 14 CFR Parts 91 and 21. Following that we’ll discuss and talk about some of the recent activities that have been taking place in the past few years in this field of aviation. The severity of a General Aviation accident is classified by the highest level of injury (that is fatal, serious, minor or none) and the total aircraft damage (destroyed, substantial, minor or none). Finally we will compare and analyze historical General Aviation accident rates between the years of 1995 and 1999 from the National Transportation Safety Board (NTSB). Introduction Aviation is classified into three broad types that are Military Aviation, Commercial Aviation and General Aviation. General Aviation is defined as any civil aircraft operation that doesn’t fall under 14 (Aeronautics and Space) Code of Federal Regulations (CFR) parts 121,129 and 135. The operations that are included in General Aviation are that of U.S. registered aircraft operated under 14 CFR Parts 91 (General Operating and Flight Rules), 21 (Certification procedures for products and parts) and civilian public use (Qualified government missions that may include law enforcement, low-level observation, aerial application, firefighting, search and rescue,......

Human Error in Aviation

...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 along the process. There is continuous communication taking place between the different sectors, from the aircrew, to air traffic control, to maintenance, and all the other facets in between. Any position in aviation can be very......
