An aviation accident is characterized by the Сonvention on Іnternational Сivil Аviation Аnnex 13 as an circumstance correlated with the conveyance of an aircraft, which takes place during the planes’ journey; Where a person suffers from injuries or the plane sustains damage and it’s missing or inaccessible. Plane crashes can occur by all ranges of causes from human error to weather related. An occurring accident usually results in a high amount of casualties which leaves a bad mark on aviation. As such, people usually doubt the safety of plane crashes. I, myself, am really curious about this and thus I am making this project which will investigate the causes and prevention of plane crashes.

These major disasters sparked the need to build on and continue the need to improve the overall safety of aviation.
Tenerife
The Tenerife disaster, which occurred on March 27, 1977, remains as the accident with the highest number of casualties. Where 583 lives were perished when a KLM Boeing 747 attempted to take off without clearance and collided with a taxiing Pan Am 747 at Los Rodeos Airport. Unfortunately, there were no survivors from the KLM aircraft; 61 of the 396 passengers and crew on the Pan Am aircraft survived. From the incident, we can infer that pilot error was the primary cause.
Owing to a misunderstanding with the ATC, the KLM captain understood he had clearance for take-off. Another cause was dense fog, meaning the KLM flight crew was incapable to notice the Pan Am aircraft on the runway until just shortly before the collision. The accident particularly made changes to the area of communication so as to prevent such crashes from occurring. The word “take-off” was removed from general usage as a result and can be only spoken by ATCs.

However, a voluntary negligence for a standard operating procedure (or warning) is still considered to be a pilot error, even if the actions face criminal charges. Pilots may fly into bad weather as they are not being able to interpret the current situation. Some reasons for pilot error may come from fatigue, spatial disorientation, lack of situational awareness and even intentional causes such as suicide. Pilots may not know their current situation and such they will crash into the ground. Notable examples are the Tenerife incident where the pilot was not able to spot the KLM aircraft and miscommunicating with the ATC. Polish Air Force Tu-154 where the pilot crashed into the ground due to not knowing his current altitude. Another is the Germanwings Flight 9525, where the co-pilot deliberately crashed the aircraft due to his suicidal intentions killing all 150 people on board.
Pilot error may also result in the mid-air collision. Mid-air collision is an aviation accident in which two or more aircraft come into contact during flight; having high speeds involved or any subsequent impact on the ground or sea. Usually resulting in a complete structural failure of least one of the aircraft involved.
Airplanes usually crash in mid-air when pilots from both or one aircraft fail to look at their surroundings, ignoring ATC, or even look at the plane's radar. A notable example was the Charkhi Dadri mid-air collision which involved a B747 and
Weather conditions- Sometimes the bad weather conditions become the huge problem for the aircrafts as they are not able to operate in bad conditions by which they get losses.
The National Transportation Safety Board determines that the probable cause of this accident was the failure of the flightcrew to monitor the flight instrument during the final 4 minutes of flight, and to detect an unexpected descent soon enough to prevent impact with the ground. Preoccupation with a malfunction of the nose landing gear position indicating system distracted the crew's attention from the instruments and allowed the descent to go unnoticed.
The investigation was also one of the largest international law enforcement endeavors of its time (Birkland, 2004). This tragedy, like most devastating events, changed the course of history and is a directly affected aviation safety as we know it today. The forensic findings during the investigation also helped change aviation safety policy and procedures. The result was improvement in training for airport security personnel, examination of quality control issues and heightened aviation security regulations (Birkland,
The Colgan Air Flight 3407 was a very interesting case to look at. On February 12, 2009, at 10:17 pm, flight 3407 crashed at a house in New York after the pilots experience a stall. Flight 3407 was scheduled to fly from Newark, New Jersey to Buffalo, New York. The NTSB reported the cockpit voice recorder (CVR) revealed some discrepancies both pilots were experience. The first officer did not have any experience with icing condition but icing was one of the reasons the plane went into a stall. On the other hand, the captain had some experience flying in icing condition. The captain was experiencing fatigue, which indeed, made him unfit to recover from a stall. With that in mind, the Human Factor Analysis Classification System (HFACS) will give insight of some errors both pilots made.
On July 17, 1996, Trans World Airlines flight 800, A Boeing 747-100, exploded and crashed into the Atlantic Ocean near New York 12 minutes after its departure. All 230 people on board died.
September 11, a turning point in the United States history. This event caused various negative impacts on the aviation industry. It changed the way airports and airlines organized themselves completely. The effect was so strong that it caused bankruptcies, people to lose their jobs, changes in how flights were made and flew, and security checking’s. This day also created fear and psychological issues on individuals concerning anything to do with flying on an airplane. In other words, this day was a catastrophe in the aviation industry in the US.
As a conclusion, I hope these previous paragraphs have given you the knowledge that everyone dealing with physics or airplanes should possess. These factors may not show all that physics has to contribute in the flight of an aircraft but they do show the major contributions. After reading these paragraphs, you should now have greater respect for physics, not just in airplanes, but in the world, because it is all around you and nothing can exist or work without it.
Nearly all pilots have experienced a strange phenomenon during landing. While everything is happening as it should during decent, a 'cushion' of air gets trapped below the wing during the last few meters to the runway. This throws off the rate of decent and can be dangerous if the pilot has already begun to flare up and decelerate for landing. This means the plane would climb again while slowing down, which would easily lead to a stall.
In conclusion, many contribution factors led to the Crossair flight 3597 crash but is mainly triggered by Crossair’s incapability of assessment, pilot error and lastly the air traffic controller. Analysis of a flight crash is important so that we will know the causes, thus being able tackle it, making sure that there are no other flight crashes like Crossair flight 3597.
Throughout time it has appeared that most accidents have indeed occurred because of human error. For example, one case of human error would have to be the loss of a sailing yacht called Revonoc, occurring in 1958. This craft belonged to Harvey Conover, a business man of his time. It turns out Harvey Conover sailed his yacht into the eye of a storm. Nobody had ever seen Harvey ever again. (www.bermudatriangleinfo.com)
Automobile accidents happen all around us. We see cars in the middle of the road after just rear ending each other. We see cars driving around town with big dents in them. Do you ever stop to wonder how car accidents happen? Physics; that’s how they happen. There are several aspects of physics that apply to automobile accidents.
Travelling at a speed twice that of sound might seem to be something futuristic; however, this feat has already been achieved almost 40 years ago by the world’s only supersonic passenger aircraft-The Concorde. Concorde brought a revolution in the aviation industry by operating transatlantic flights in less than four hours. The slick and elegant aircraft with one of the most sophisticated engineering was one of the most coveted aircrafts of its time. However, this was all destined to end when Air France Flight 4590 was involved in a tragic disaster just outside the city of Paris on July 25, 2000. The crash killed 113 people, but more disastrous was its impact. The belief and confidence people had with Concorde gradually started to fade, and finally Concorde was grounded after two and a half years of the crash. Official reports state that the main cause of the crash was a piece of metal dropped by a Continental aircraft that flew moments before Concorde, but, over the last decade, the report has met a lot of criticism, and many alternative hypotheses have thus been proposed.
... problem are under constant development and analysis, in a hope to avoid these situations. The civilian industry continues to lead in development due to commercialization, with the military not far behind. The only real deficiency in CRM program development seems to be the area of general aviation as described earlier. Until this problem is addressed, there will still be a glaring weakness in the general area of aviation safety. However, with the rate of technology increase and cheaper methods of instruction, we should begin to see this problem addressed in the near future. Until then, aviation will rely on civil commercial aviation the military to continue research and program development for the years to come, hopefully resulting in an increasingly safe method of travel and recreation.
As the development of aviation industry grows, more and more aircraft crashes occur. There are many reasons that lead to aircraft crashes, but one of them, is because of improper aircraft maintenance. Why is proper aircraft maintenance so important? Proper aircraft maintenance is critical in order to keep the aircraft can function properly, every aircraft part is in good condition and ensure the safety of pilots and passengers. Proper maintenance has many parts. The most common part is inspections, which pilots do them every day; the main part is overhaul and repair of an aircraft; and maintenance documentation is another important part of aircraft maintenance which improper maintenance documentation has caused many incidents.
The primary cause is of airplane accidents does at some stage contain an element of a person being unable to discharge his duties correctly and in an accurate manner. More than 53% accidents are the result of ignorance or faults by the pilot during flight. Other staff is responsible for about 8% accidents. The most obvious errors by pilot are made during the take off or landing on the runway. Additionally errors can occur during the maintenance of the airplane outside the plane, whereby a lack of thorough inspection and oversight can lead to complication during mid-flight. Fueling and loading of the plane also sometimes create problems (Shapiro, 2001).
