Airline Safety Essays - Aircraft Maintenance, Aviation Safety

Airline Safety Airline Safety Many people travel by airplane all around the world. For some people it is the only way they can get to where they are going. On a daily basis, averages of 28 to 30,000 seats are filled on airplanes (Bear, Stearns Co. URL www.hotelonline.com). At each airport, there are hundreds of arrivals and departures worldwide. Even though airline officials say flying is safe, accidents kill many people because airlines neglect to prevent human error or repair faulty equipment. Sometimes I think the only reason an airplane could crash is if something on the plane were to break. However, most of the time that is not the case. A survey conducted by Boeing found that flight crews were responsible for at least seventy-three percent of all fatal airplane accidents. (Gray 17). Forty-one percent of these accidents occurred during landing because of unstable approaches. Also an investigation by the National Aeronautics and Space Administration on the causes of airline accidents revealed that more than eighty percent of all airline accidents involved some degree of human error (Helmreich 62). This is very alarming when people are putting their lives in the hands of flight crews. Forty-four passengers died aboard a new British Midland 737 after its crew shut down the wrong engine after the other one malfunctioned (Greenwald 40). Do you really think that flying on an airplane, over which you have absolutely no control is very safe? Reasons for flight crew error can be explained by the conditions under which they are flying. Flight crew fatigue is a largely increasing problem on many of the jumbo jet flights today. Although there are laws that prohibit cockpit crews from sleeping in flight, there have been many weary pilots that have been known to nod off on occasion during some of their seventeen hour, non-stop flights (Urquhart 15). Perhaps laws should regulate the number of hours a flight crew is in the air instead of prohibiting sleep in flight. Another condition, alcohol abuse, has been found to inhibit the abilities of some flight crews. A northwest crew flying from North Dakota to Minnesota was found to be intoxicated on the job (Air Safety 61). Some people refuse to drive at night because of the number of drunk drivers on the road. Would passengers want a drunken pilot to be responsible for their lives while 20,000 feet up in the air? Another reason for flight crew error is pressure to meet flight time schedules. Some of these flights take place during hazardous weather conditions. When I was younger, I saw an airplane crash at the St. Louis Airport after the pilot was ordered to take off even though the plane had ice on its wings. The airplane skidded off the runway because the pilot could not control the steering mechanisms on the icy runway. Other incidents have occurred solely because of bad weather and an urgency to stay on schedule. When flight 803 came in to land at Tripoli, the pilot decided to land the plane even though a dense fog covered the runway. One hour earlier a Soviet jet scheduled to land at the same airport detoured to another to avoid the fog. There were no mechanical malfunctions of the plane; however, it missed the runway by more than a mile, cartwheeled, and slammed into two farmhouses (New Qualms 20). Another accident, which killed most of the passengers on board, occurred when an Air Flor ida Boeing 737 crashed into the Potomac River near Washington, D.C. in 1982. The speed gage for take off was covered with ice which caused the takeoff acceleration to be miscalculated (Helmreich 62). The most avoidable reason for an airplane to crash is faulty equipment that could have been repaired or replaced. A cargo door and part of the outer layer covering tore away from a nineteen year old Boeing 747 shortly after leaving Hawaii, sucking nine people out of the plane and sending them to their deaths over 20,000 feet to the sea (Greenwald 40). Investigators determined that the cause of this disaster was a single faulty door lock. This insignificant door lock could have been replaced many times so that such a disaster and loss of life

Psych Drugs And Dreams Essay

Psych Drugs And Dreams Essay Psych Drugs And Dreams Essay Hang Ma AP Psych Mrs. Lawson 9 March 2015 Mini Unit: Dreams 1. In all of the dreams, the theme is abandonment, because she is deserted by her friends and left alone, stood up by her mother on prom night, left by her favorite teacher Mr. Stevens, and scared by her older self. It relates to her life in that she has no male friends, that she lives with her mother but not her father, and that she likes to be the center of attention. 2.Displacement happens in dreams #1 and 3, Mr. Steven and her friends represent someone who left her in her fact. In the second dream, she has a wish fulfillment of striking her the strange man for revenge. In dream #4, a condensation appears in the form of her face on an older man’s body but the face looks 40 years older and evil. 3. I believe that Debbie is suffering from unresolved issues because of her father’s abandonment. Dream #1 resembles her memory as a younger child, sitting in the middle of her room crying because her parents are not there for her. Because of this, Debbie is afraid of having male friends and fears that they will leave her. Also, her dream of Mr. Stevens leaving her and her resulting calls for him stem from her past cries for her father. Dreaming about the man with an evil version of her own face suggests that she is angry at her father, because she crushes a Coke can afterward. In addition, Debbie’s anger is further supported by her striking of the man in dream #2. Long-Term Effects of Drugs on the Brain 1. After a period of time, drugs can trigger the amygdala and cause urges. The most startling way drugs can change the brain is their ability to destroy neurons, though a close competitor would be their potential for slowing down brain activity. 2. The brain builds tolerance to eliminate it more effectively, which in turn leads to taking greater amounts of a drug. 3. Drugs that kill neurons can decrease the plasticity of the brain because the neurons then are not present to form new connections and existing connections are lost as a result. 4. The problems scientists could have include: The brain’s complexity, the tendency of drug abusers to abuse more than one drug, and the health

Tarrifs and Trade Essay Example | Topics and Well Written Essays - 500 words

Tarrifs and Trade - Essay Example Thus, the overall effect of a tariff implemented by a small nation must reduce the national welfare (Nunn & Trefler, 2010). Thus, whenever a small country will implement the tariff, the national welfare is bound to fall, and the higher the tariff will be set, the more the loss will be experienced and consumers will lose as government recipients and producers spending gain. In a large country, consumers of the good suffer from the price increase, as the producers will experience a well-being increase from the tariff. Thus, the tariff net effect is composed of three major results that are a negative distortion in production, positive trade effect terms as well as a negative consumption distortion. Thus, there are both positive and negative elements as the effect can be either negative or positive. However, the overall result is that it can be positive implying that a tariff that is implemented by a large nation may increase the national welfare (Debaere & Mostashari, 2010). Unlike quotas, tariffs are important as they generate the government some revenue. The US according to statistics collects over 20 billion a year from revenue from tariff that could be lost with quotas (Motoshige Itoh & Yoshiyasu Ono, 1982). Another reason is that quotas may result in administrative corruption. Tariffs provide customs officials with authority and power providing access to favored organizations and denying the lesser-favored ones as opposed to import quotas. Moreover, import quotas have a high probability of causing smuggling especially when set at unreasonable values (Grant, Hertel, & Rutherford, 2009). A strong dollar is good while, on the other hand, weak is bad. As the generalization sounds simple, it is very different and confusing when it comes to the dollar. A strong dollar is very strong when compared to other foreign currency, and the vice-versa is

Destination marketing strategy- patagonia Essay

Destination marketing strategy- patagonia - Essay Example in the previous assignment, however the hard adventure segment has shown promising growth over the past 5 years in a global perspective (Adventure Travel Trade Association, 2013). This makes Patagonia a lucrative business proposition for tourism companies. The customers who are considered as the hard adventurers are mostly looking for challenging tours in places with hostile environment. Such people will strong appetite for adventures will get strongly attracted to Patagonia, owing to its extremely cold environment (U.S. Commercial Service, 2012). Despite of the strong potential of Patagonia as a destination place, there are significant issues with the location. The TWOS matrix conducted in the assignment presentation clearly indicates towards the issues with the health and safety concerns owing to the poor regulations. Moreover, in Patagonia high quality accommodation cannot be expected and at the same time language problem is always a problem. However, while targeting at the hard adventurers, these issues may not pose as drastic challenges as it might to the soft adventurers. This is mostly because the hard adventurers more attracted towards challenging situations. Thus it can be stated that Patagonia can be a potential tourist destination for hard adventurers. This section focuses on the strategies that are appropriate for attracting the target customers. The target customers selected for the Patagonia tourism are the hard adventurers. Before designing any strategies for attracting the target customers, it is imperative to have detailed discussion regarding the behavioural and psychological aspects of the customers (World Tourism Organization, 2007). The global tourism can be divided in to two definite segments, one is for the soft adventurers and the other is for the hard adventurers. The soft adventurers include average tourist who are enthusiastic to see new places and gain new experiences about a particular region and its culture. These individuals usually

Philosophy and the Future Assignment Example | Topics and Well Written Essays - 1250 words

Philosophy and the Future - Assignment Example The last theory that he put forward was that a person should accept the fact of absurdism and in this way, he would lead a better life. The reason behind this is that a person knows that life has no meaning and in that way, he would live his life to the fullest. Absurdism is one philosophy which actually denies a proper meaning to life. Many philosophers have argued against this. If absurdism is a belief that is universally accepted then it can be argued that the meaning of philosophy itself is nothing because since life has no purpose then why should one actually assess its outcome and search for a way of living. Not believing in life would actually mean not believing in one’s own existence. A logical explanation to the meaning of life is essential and it must be considered. The meaning of life is one thing that a person must analyze so that he understands his own existence. It is something that a person derives from learning and knowledge. Absurdism is actually an easy way out that a person discovers when he denies his search of life. Absurdism is actually living a life of self-denial. Meaning of life can be understood on the basis of religion as is accepted by many. It can also be based upon the principles of utilitarianism which i ndicates that the purpose of leading a normal life is dependant upon the principle of happiness which indicates that a person performs those acts which would bring about the maximum happiness. Religion and utilitarianism teach a person about his own existence, about the purpose of life and the creation of a happy and healthy world. Human beings are finite beings. Despite that many philosophers have put forward the theory about the existence of God who as explained is an infinite, Supreme Being. This means that human beings definitely have the power to consider and examine the infinite being.

Virus, Worms and Hackers :: Computers Technology Essays

Virus, Worms and Hackers Computer viruses were first widely seen in the late 1980s. They were caused due to several reasons. The first factor was rapid growth of personal computers. Before this decade personal computers were not seen in many houses. They only computers used were expert computers which were locked in laboratories around the world. During the 1980’s Computers started to sell to several smaller business’s and homes after the release of the IBM PC in 1982 [1]. After its launch, personal computers slowly started spreading to businesses, homes and universities around the world. The second reason was bulletin boards where users could dial up a bulletin board with a modem and download different programs [2]. The most popular programs were games. Users also downloaded simple word processors and spreadsheets. Bulletin boards led to the precursor of the virus which is know today as the Trojan horse. Trojan horse is a program which can trick the user in to downloading it. This can be done very easily changing the name of the file. When a Trojan program is downloaded on a local computer it can do a lot of harm to it. It can potentially erase all the contents of the hard disk on the computer. Trojan horses hit a small number of people because they are discovered easily. Either the bulletin board would erase the file from the system or the people would send out messages to warn one another. The third reason was growth of floppy disks. Many programs could fit into a single floppy disk. Most computers did have hard disks so computers would just load everything off the floppy when switched on including the operating system. Computer viruses can be very mysterious and grab our attention. Viruses can show us how vulnerable we are to attacks. A well engineered virus can have a very harmful effect on the internet. An example of this is the worms we have seen in the last few years. MyDoom worm which infected a quarter million computers in a single shook the whole internet community. In March 1999 the Mellisa virus was so powerful, it forced many large companies including Microsoft to completely turn off their email systems until the virus could be contained. The ILOVEYOU worm in 2000 had a similar effect. The most astonishing thing is that these worms were very simple in their implementation. Worms usually exploit some sort of security hole in a piece of software or operating system.
