QZ8501 suffered from the phenomenon of

The first bodies of victims on the QZ8501 plane were found, but the cause of this catastrophic accident is still a secret.

Many judgments say that AirAsia airline QZ8501 has been in distress because the phenomenon of 'coffin corner' like Airbus A330 aircraft with the number 447 of Air France was in distress in Brazil in 2009.

QZ8501 accident location

According to information provided by the relevant authorities, before the plane crashed, the pilot of the QZ8501 contacted the Indonesian air traffic control station to propose to increase the altitude of the aircraft and turn left to avoid an area. complicated weather.

However, just a few minutes later, the plane suddenly disappeared on the radar screen of Jakarta air traffic control station.

Airline experts say that raising the altitude to the aircraft's permissible ceiling will lead to the phenomenon of 'coffin corner' (Q corner) causing the plane to stall and fall vertically. . This may be the reason for the crash of the QZ8501 aircraft.

Accordingly, the more the plane flies, the more dilute the air is while the wing area is constant, making the aircraft fly faster so that the wing has enough lift. Flying too slowly, the plane will fall.

However, if you fly quickly, the amount of air passing through the wing will reach a speed close to or higher than the speed of sound (while the aircraft is still flying at speed below sound).

At this speed, the shock waves formed from collisions between the air flow and the wing surface will tend to push the nose to the ground. Flying too fast, the plane will plug straight into the sea.

At higher altitudes, the distance between these two important speed points is gradually narrowed. And at a height where these two times meet, the plane will lose control and plug its head into the sea. People call this phenomenon 'coffin corner'.

Describe the "coffin corner" phenomenon (Q corner or Coffin Corner)

In 2009, Air France Airbus A330 aircraft number 447 was also reported to have suffered an accident due to this 'coffin corner' phenomenon.

The French Airbus A330 also skyrocketed in trouble during stormy conditions before losing control and abruptly fell into the sea on June 1.

Some experts also said that the decision to increase the QZ8501's height also increased the risk of "collisions" with storms formed at a height of 12,000 meters which is very dangerous.

No matter how advanced, no plane can fly through the enormous storm clouds inside the heart of the storms. Vertical winds in this area can cause destruction to even the largest aircraft.

In fact, today's modern weather radars can help pilots fly around storms. However, many low-cost airlines have been forced to cut this modern feature to ensure profits and not rule out AirAsia to do this.

Currently, the first bodies of victims in the QZ8501 plane crash were found. However, the cause of this catastrophic accident probably still takes time to find the answer.
