49% of air crashes occur during the landing phase. This is a landing video taken by 12 captains in the cockpit, feeling the thrilling moment of landing from the perspective of a pilot. Narrow runways in icebergs, blind landings in fog, carrier-based aircraft landings on aircraft carriers, night scenes in New York and Tokyo, more than 100 tons of airliners in the wind like a leaf, today to experience the feeling of being a captain.
There is a saying in civil aviation circles: 11 minutes of danger. This means that the 3 minutes of the aircraft accelerating to take-off and the 8 minutes of the landing phase are the most accident-prone stages of the aircraft and the most testing time period for the pilot.
According to relevant statistics, flight accidents that occur 8 minutes before the landing of passenger aircraft account for about 50% of the total flight accidents, and the accidents that occur 3 minutes after take-off add up, accounting for more than 70% of the total number of accidents.
Especially in the landing stage, the accident rate is as high as 49%, it is too difficult to fly the plane, this is the moment when the 12 captains landed, each landing is a collision with the god of death, it seems to be a beautiful night view of New York and Tokyo, but behind this contains endless danger, the captain's hand of the joystick is tied to hundreds of lives.
Boeing's long-term investigation found that the aircraft flight is divided into 7 stages: taxi, take-off, climb, cruise, descent, approach and landing, of which take-off and landing are the most dangerous 2 stages. The take-off phase accounts for only 2% of flight time, and the accident rate is 14%. The cruise phase accounts for 57% of the total flight time, and the accident rate is only 6%. The landing phase accounted for only 4% of flight time, but the accident rate was as high as 49%.
At the beginning of the design of the aircraft, the performance of the cruising flight was mainly considered, which was safe, comfortable and fuel-efficient, so the state of the aircraft components in the cruise stage was the most stable and reliable. Passenger aircraft generally fly in the stratosphere, because the stratospheric atmosphere basically does not move vertically, the atmosphere is dominated by stratospheric movement, and occasionally chaotic is not a big problem, so that the passenger aircraft is relatively stable, and the stratospheric water vapor, less dust, high visibility, but also fuel saving.
Passenger planes spend about 57 percent of their time flying in the stratosphere, and if some accidents occur, pilots will have a longer time to resolve. The take-off and landing phases of the aircraft are very short, for example, there are 5 stages of approach: the approach stage, the initial approach stage, the intermediate approach stage, the final approach stage, and the resumption stage.
In the take-off and landing stage, the passenger aircraft is located in the troposphere, the troposphere is the lowest layer of the atmosphere, the largest density, including all the water vapor and aerosols in the entire atmosphere, the air movement up and down convection, the weather is complex and changeable, look at Figure 10 to know why hundreds of tons of aircraft, blown like leaves, all very dangerous.
Danger 11 minutes not only refers to the complexity and danger of the situation, but also the time left for the pilot to deal with is extremely short, and it is possible to destroy the aircraft in a single instant. The instrument should receive the guidance signals such as the ground heading platform, the sliding platform, and the beacon station at the same time, and the pilot should deal with various emergencies and pay attention to various data such as the heading and altitude of the aircraft, which is the most tense and busy stage.
When the pilot maintains close contact with the tower, he must also accurately control the course and altitude of the passenger aircraft, otherwise there is a danger of flying out of the safety zone, causing landing failure or air disaster. Every take-off and landing of a pilot is a huge test.
Passenger aircraft also face punctures, runway pollution, bad weather, low-altitude conflicts, low visibility, bird strikes, etc. when landing, which occur during the take-off and landing phases of the aircraft. On January 15, 2009, an Airbus A320 flying from New York to North Carolina was "attacked" by birds after takeoff, and both engines were sucked into the birds, and finally forced to land on the Hudson River, and the photos of people standing on the wings of the plane waiting for rescue are classic.
The above problems and carrier-based aircraft landing on the aircraft carrier, the real small witch, the take-off and landing of the carrier-based aircraft is called "dance on the tip of the knife", the runway is only about 100-200 meters, the carrier-based aircraft can not turn off the engine when landing, but to drive the engine to the maximum, in order to return to flight after the landing failure, and to accurately hook the blocking cable, which is much more difficult than landing on the land. #知识迎虎年, open and hang for a whole year ##Rumor Zero Plan ##Airliner ##飞机 #
