Does the rain affect the flight of the plane?

Influence of precipitation on flight

Precipitation reduces visibility; Too cold raindrops can cause aircraft to accumulate ice; Broken rain clouds produced by precipitation affect the take-off and landing of aircraft; Strong downward flow is easy to appear under heavy rain; Heavy rain and rainstorm can turn off the engine; The heavy rain deteriorated the aerodynamics of the plane; Precipitation affects the use of the runway.

1On the evening of February 24th, 989, when a viscount plane landed at Hangzhou Airport at night, it was raining, and the pilot's misjudgment led to a flight accident.

1985 June 12, a Sveringen SA-226 Mitro plane of Wisconsin Airlines of the United States was hit by a thunderstorm when landing in Nebraska, and two engines were shut down due to heavy rainfall, resulting in the plane crash.

The harm of other bad weather to flight

Second, the impact of bad weather on flight safety

1, the influence of wind shear on flight

Wind shear shows a sudden change in the speed and direction of air flow. When the plane flies in this environment, there will be a sudden change in airspeed. The change of airspeed causes the change of lift, and the change of lift causes the change of flying height. If the airspeed drops suddenly and the pilot doesn't take immediate measures, the plane will fall from the height and even have an accident.

On April 4th, 1983, Wang -200 aircraft of China Nanhai Oil Joint Service Company Civil Aviation Helicopter Company encountered low-altitude wind shear during take-off, stalled and fell to the ground.

1991On April 25th, China Southern Airlines flight B757/280 1 encountered moderate windshear when approaching Kunming Airport, and the plane was damaged when it landed again.

On June 22, 2000, the Yun Qi plane of Wuhan Airlines encountered a thunderstorm when approaching Wangjiadun Airport in Wuhan, and crashed due to a microburst.

2. The influence of thunderstorm on flight.

Thunderstorm cloud is a "weather factory", which can produce all kinds of weather phenomena that endanger flight safety-strong turbulence, ice accumulation, lightning strike (lightning strike), thunderstorm, strong wind, and sometimes hail, tornado, downward flow and low-altitude wind shear. When the plane strays into the thunderstorm activity area, it will cause human and machine injuries, and the most serious situation is that the plane is destroyed and people die. Therefore, thunderstorms are recognized by aviation and meteorological circles as a serious threat to flight safety.

In March, 1990, China Eastern Trident B2208 encountered a thunderstorm when entering Guilin Airport, and the plane ran off the runway.

1988 On August 3 1 8, Guangzhou Trident 22 18 landed abnormally at Kai Tak Airport in Hong Kong in thunderstorm weather and rushed into the sea.

On May 8th, 1997, China Southern Airlines B737 was caught in moderate to heavy rain during its landing at Shenzhen Airport, and the plane ran off the runway and crashed.

On July 20th, 1994, Yunnan Airlines B737 plane ran off the runway while landing at Kunming Airport.

3. The influence of turbulence on flight.

When the turbulence is strong, it is difficult for the pilot to control the plane, and even temporarily make the plane out of control, or damage the structure of the plane, leading to accidents in which the plane is destroyed and people are killed. Bump makes the fuselage vibrate, which will obviously reduce the amount of air entering the engine airway, and in serious cases, it will cause automatic stop. Strong bumps will make the crew and passengers very tired, dizzy and nauseous. Especially sudden and strong bumps, if you don't fasten your seat belt, it will cause passengers casualties.

On June 25th, 2002, 65438+ China Southern Airlines B757 carried out the Shenzhen-Wuhan mission. When the plane descended to 7800 meters, it suddenly encountered severe bumps, resulting in 1 flight attendants being injured and 5 passengers being frightened to go to the hospital for examination.

On May 22nd, 1992, a B767 plane flew from Shanghai to Beijing. At an altitude of 90 kilometers and 9000 meters south of Jinan, it was hit by a powerful jet stream and a clear sky, injuring four flight attendants and several passengers.

4. The influence of clouds on flight.

Cloud is a meteorological condition often encountered in flight, which often affects flight activities. The impact on flight mainly includes: clouds with low cloud bottom height affect the take-off and landing of aircraft; The visibility in the cloud is very poor, which affects visual flight; The supercooled water droplets in the cloud make the plane accumulate ice; Turbulence in the clouds causes the plane to bump; The uneven light and dark in the cloud can easily make the pilot have an illusion; And lightning in the clouds damages the plane and so on.

1981April 2 1 day, the Beijing civil aviation bureau BO- 105 plane took off from the No.4 drilling platform in Beibu Gulf, South China Sea. Due to the bad weather, the pilot hallucinated and the plane flew into the sea.

1993101On October 26th, when an aircraft of China Eastern Airlines landed at Fuzhou Airport, it ran off the runway due to rain and low clouds.

1985, three An -24 planes crashed when they landed at the airport due to poor visibility.

5. The influence of precipitation on flight.

Precipitation reduces visibility; Too cold raindrops can cause aircraft to accumulate ice; Broken rain clouds produced by precipitation affect the take-off and landing of aircraft; Strong downward flow is easy to appear under heavy rain; Heavy rain and rainstorm can turn off the engine; The heavy rain deteriorated the aerodynamics of the plane; Precipitation affects the use of the runway.

6. The influence of wind on flight

Wind has a great influence on the take-off, landing and navigation of aircraft. According to the statistical data of1951-1991,there were two flight accidents caused by strong wind or crosswind.
