Since a long time research have been in this filed which now a days finally lead us to the modern aviation industry. An anomaly is a deviation from the normal or expected behavior. Anomaly Detection is that property which is used to identify cases, which do not conform to an expected pattern. This has a great role in aviation filed to analyze the data and helps us to study about it, which finally helps us to maintain high-level safety in airlines operation.
Motivation Aviation safety is one of the major concern for everyone who is directly or indirectly involved in this sector. As since last five decades we can see that aviation safety have been improving steadily. Similarly accident rate has also decreased significantly. In last decade, accidents rate had also been stable. Not only these, but also
The airline industry is one of the largest global industries in the world. Airline companies in the airline industry have gone through challenging obstacles in the past decade. Many changes have occurred within the industry and increased regulations have driven up cost for the industry. The attacks on 9/11 left the industry in shock when planes were used in terrorist attacks in the United States. These attacks changed the mentality of the industry and shifted the focus towards safety. Safety was also a major concern in the industry with the breakout of SARS in 2003 and the H1N1 flu in 2009. The airlines had to ensure that public health and safety of the travelers were
According to Kuhn, the term “anomaly” refers to the “recognition that nature has somehow violated the paradigm-induced expectations that govern normal science” (Kuhn, 2012, p. 53). Kuhn believed that novel discoveries began with the recognition, or awareness, that an anomaly exists, and the area related to the anomaly is explored. Kuhn adds that an awareness of an anomaly does not confirm that there will be future research endeavors aimed at further exploring the area surrounding the recognition of an anomaly. For example, “anomalies can be ignored, denied, or unacknowledged”
Airport safety is one of the Federal Aviation Administration's biggest concerns. They are tasked with tracking over 10,400,000 commercial flights every year, not including military and non-commercial flights (Canavan). Collisions and crashes are the two major causes of injuries and death. Air travel accidents date all of the way back to 1908 (Old). Orville Wright, one of the original inventors of the airplane, was flying a demonstration for the military when a propeller suddenly was ripped off of the airplane. The passenger, Lieutenant Selfridge was killed when the plane hit the ground (Old). The Federal Aviation Administration has come a long way since the 1960’s to improve safety (Mission). They have implemented various systems such as the United States program, NextGen Program, and the Air Transportation
Ever since I was little I was amazed at the ability for a machine to fly. I have always wanted to explore ideas of flight and be able to actually fly. I think I may have found my childhood fantasy in the world of aeronautical engineering. The object of my paper is to give me more insight on my future career as an aeronautical engineer. This paper was also to give me ideas of the physics of flight and be to apply those physics of flight to compete in a high school competition.
The concept has since gained worldwide recognition in several industries, especially high-risk industries, such as nuclear power and aviation.(Clarke 1999). When safety is
“For once you have tasted flight you will walk the earth with your eyes turned skywards, for there you have been and there you will long to return.” This quotes date back to the 15th century which informs us that aviation was thought off back to the middle ages. To this day, many aviators contributed to aviation in many different aspects. Throughout the past century, aviation has progressed significantly. “airplanes were starting to fly higher and faster thanks to new streamlined fuselages and powerful jet and rocket engines.” (Teitel, 2015). Unfortunately, there was not any adequate safety measures provided for pilots and passengers which were prone to dangerous crashes. It was not till Colonel John Stapp, a decorated Air Force flight surgeon,
The airline industry has some current undergone radical changes in which how he operates. This fact makes it impervious that each airline challenges to find those personalities on which
Researches have continuously been working on ways to reduce loss of control in flight accidents for general aviation operations, focusing on the implementation of flight envelope protection systems in the aircraft to simplify piloting, reduce pilot workload, and allow low-end general aviation aircraft to operate under deteriorated meteorological conditions (Falkena et al., 2011).
As the years progress, airplanes have been regarded as the handiest method to experience all the foreign nations since the 1950s. There is no denying that the impact on aviation on human history is vital. Hence, the public anticipates that the industry is approximately perfect. Nevertheless, with the collisions of the past aircraft, it is evident that misapprehending the communication between the air traffic controllers and pilots account for mortal accidents. Consequently, I am going to compare two aircraft accidents in the past and analyze how the tragedy resulted from.
Socio/cultural, economic, political, and technological are all factors that influence the airline industry (Boyens, Cha, Livneh, Pan-Fea, Singh, & Vintrou, 2002). The most important socio/cultural influence that affected the airline industry was the attacks on September 11th. The Department of Transportation reported a revenue drop associated with an increase in operating cost and a new fear of flying. After September 11th, Jet Blue was one of only a few airlines that made a profit during a sharp draw down in airline travel (“Jet blue airways”, 2003).
The STAP’s theory was published by Lawrence E. Brennan and Irving S. Reed in the early 1970s. Space-time adaptive processing (STAP) is a signal processing technique which is most commonly used by radar systems. Radar signal processing benefits from STAP in areas where interference is a problem (i.e. Ground clutter, jamming, etc.). It is very easy to find the target using this method. STAP uses a two-dimensional filtering technique using a phased-array antenna with multiple spatial channels. To implement STAP an antenna array is used, over a several pulse repetition intervals. The output of this is a linear combination or weighted sum of the input signal.
With the aviation industry exponentially expanding it is essential to ensure that those safety standards which are in place are working effectively. It is primarily the responsibility of the Chief Executive Officer (CEO) to ensure that his or her airline is not only profitable but is also safe. The balance between production and protection is a fine line and as such there need to be systems in place to ensure production is not outweighing protection.
As an industry, aviation is not immune to changing economics, low demands, and threats. Throughout the history, there have been hundreds of airlines formed, but some have already disappeared and some are still going strong. Aviation industry is constantly being challenged by economic status, organizations, and individuals which affect the revenue, growth and profitability of each airline. Tragic events that took place on September 11, 2001 put a huge dent in the industry but currently in the process of recovering slowly and steadily. Demands for air transportation is constantly on the rise even with occasional sets backs encountered by the industry such as; terrorism, changing economics, skyrocketing fuel prices, demand changes, and increasing competition.
How important is airline safety to the flying public? How safe is it for passengers on commercial airline flights? What are the issues that prevent air travel from being as safe as it needs to be? How effective are airline safety investigators in terms of locating flaws and anomalies that might become serious safety problems? This paper delves into those questions and provides research to fully examine the issues.
The airline industry has generally seen success in the many aspects involved with it – service, tourism, innovations etc. Despite the terrorism setbacks, the industry has managed to bounce back on its feet and even produce a stunning display of grit in its armoury to be steadfast in its mission to uphold everyone’s safety yet delivering impeccable service.
