Will turbulence affect flight safety?
Aircraft turbulence refers to the sudden ups and downs, side-to-side shaking and fuselage vibration in the flight of the aircraft. Aircraft turbulence is mainly caused by the aircraft flying into the disturbed airflow area, which makes the aerodynamic force and moment acting on the aircraft out of balance, and the flight altitude, flight speed and aircraft attitude suddenly change. Aircraft turbulence intensity is related to turbulence intensity, flight speed and wing load, and is usually divided into three grades: weak, medium and strong.
More than moderate turbulence will make the aircraft instrument indication abnormal and difficult to control, which will affect air formation, shooting, bombing, refueling and aerial photography. Especially serious, it will damage the aircraft structure and cause accidents. Once the plane enters the bumpy area, it can be separated as soon as possible by changing its course and altitude.
Extended data:
I. Production conditions
1, time: summer, when the seasons alternate, noon and afternoon.
2. Area: mountainous area and rough surface area.
3. Stage: low altitude, take-off and landing stage; There is also a clear sky in Wan Li, and the weather is unpredictable.
4. Meteorological conditions: cumulus, high-altitude jet, turbulence, strong wind, low-altitude wind shear, front, trough line, cyclone, thunderstorm, etc.
Second, the impact on flight driving
When an aircraft flies in a bumpy area, the altitude, speed and attitude of the aircraft often change irregularly due to the irregular change of airflow. When the turbulence is strong, the height change of the plane can often reach tens of meters or even hundreds of meters, which will bring great difficulties to the operation of the plane.
Because of this drastic change in the state of the aircraft, pilots must spend more energy to keep the aircraft in a normal state in time, so they consume a lot of physical strength and are prone to fatigue.
