In November 2015, the two pilots were arguing fiercely in the air when they suddenly noticed that the airport had disappeared and the plane crashed straight into a luxury villa, causing a violent explosion and killing all the people on board.
On November 10, 2015, seven Florida business people chartered the airline's Flight 1526, a two-engine Hawker 700 business jet with a luxurious interior and a kitchenette, and passengers chatting and laughing in the cabin.
Business jets depart from Dayton to Akron Airport in Ohio in just 35 minutes, less than a lesson. Captain Oscar is adept at flying business jets and has more than 6,000 hours of flying experience, while co-pilot Renato is slightly inferior, but also has more than 4,000 hours of flight time.
Such a combination should not be a big problem in theory, but the truth is always so unexpected. Ten minutes after the business plane flew, the air traffic control asked them to lower their altitude to 4,000 meters, and told them that the clouds on Akron Airport were thick and it seemed that heavy rain was coming, and they must be prepared. #三度知识知识达人 #
As the weather got worse, a few minutes later, the air traffic control once again reminded the drivers that due to the clouds and fog, the visibility over the airport was only 2.4 kilometers, just over the 2 kilometers allowed to land, so be careful. The business plane continued to descend altitude and when there were still 6 minutes to go to the airport, they got a not-so-good news.
A Piper plane was preparing to land from their intended runway, and if the business planes entered at the same time, it was easy to collide head-on, and for everyone's safety, the air traffic control did not hesitate to notify the business plane: "Immediately change course and slow down, drop the altitude to 914 meters, and circle in the air to wait." ”
After a while, the Piper plane landed smoothly, so the air traffic control issued a landing permit to the business plane, and the Piper plane also reminded Flight 1526 through radio that the airport visibility was just within the minimum range of the prescribed landing, and it was necessary to be careful. The captain carefully executed the checklist, found no problems, and prepared to land.
Theoretically, the voyage should have been piloted by Captain Oscar, but he had slept less than 6 hours for four consecutive nights, was in poor mental condition, and to avoid fatigue driving, he let Renato maneuver the plane. However, he did not know that Renato had flown a long flight the night before, and had complained to his colleagues: "I feel exhausted!" ”
The co-pilot Renato lowered the landing gear while slowing down according to the captain's landing instructions, but the captain felt that the current flight speed was still too fast, so he asked the co-pilot to continue to slow down. The co-pilot did not hesitate to reduce the thrust of the engine, who knew that the force was too strong, and instantly reduced the speed from 170 knots to 140 knots.
Because the speed was lower than normal, the captain had to remind the co-pilot: "Pay attention to airspeed, not too low!" ”
Incredibly, the co-pilot did the opposite, and once again reduced the speed of flight to 120 knots, which was very dangerous, and the slightest carelessness would cause the plane to be destroyed due to stalling. The captain hurried to warn the co-pilot again, and this would not work. The co-pilot thought that his operation was no problem.
He asked with some displeasure: "Please take a closer look, it is 125 knots at the moment, isn't this speed just right?" ”
The captain replied helplessly: "Then you don't have to put down the flaps, if you continue to operate like this, we will soon stall, and the consequences of stalling are unimaginable!" ”
After all, after lowering the flaps, the speed of the business plane will be reduced faster, the altitude will be lowered, and the stall of the aircraft is inevitable. It should be known that many air disasters are caused by unreasonable control or technical problems, causing the aircraft to suddenly stall, the most typical of which is the case of "Bonan Lever".
The crucial two minutes of landing, and just like that, quietly passed amid the chatter of the two pilots, at which point the plane was diveting downward at twice the rate. If the captain immediately took the initiative to take over the pilotship of the aircraft, then there was still a possibility of safe landing, but the captain was busy executing the inspection form and the on-site guidance of the co-pilot, and could not find time at all, so as to miss the last opportunity.
At 153 meters above the ground, the business plane had reached the lowest descent height, but what puzzled the two drivers was why the runway could not be seen. They looked around intently and never found a trace of the runway. As the plane rushed out of the clouds, they could see the ground clearly, but they still did not find the runway.
The two drivers did not intend to give up, and they focused their attention on searching the runway, completely ignoring the sharp changes in airspeed and altitude. A few seconds later, a harsh "shock rod warning" was issued in the cabin, at which point they realized that something was wrong, and seeing that the plane was about to touch the ground, the two tried their best to pull upwards.
Unfortunately, it was too late, the plane was like a wild horse that had lost its reins, speeding towards a luxury villa in front of it, and with an earth-shattering explosion, the business plane was blown to pieces, and all 9 people on board were killed. The question is, why did the airstrip they were looking for suddenly disappear?
In fact, when they hovered at an altitude of 914 meters according to the air traffic control requirements, they had already flown over, probably because of their first visit to the airport, the two did not notice anything unusual. The two experienced drivers were so incredulous that the investigation team pulled out their resumes to see if they were really qualified.
It turned out that they had a bad track record in their last job, and the airline hired them without rigorous scrutiny. In addition, the investigation team also found that the airline's teaching materials were too simple and the training was not rigorous enough, which were important factors that could easily lead to accidents.
Of course, the most direct reason is that the aircraft has been hovering in the air for so long that the two pilots have lost their direction and cannot find the exact location of the airport, while ignoring the changes in altitude and airspeed, and if the captain can actively control the aircraft, the results may be very different. Afterwards, the investigation team asked the airline to change the teaching materials and strengthen the daily training of pilots, which had a significant and far-reaching effect.
