With the development and progress of the society, China's aviation industry has been rapid development, people's quality of life has improved, the aircraft has become an important means of travel. However, the changes of meteorological elements and weather phenomena will affect the flight safety of aircraft in different degrees during flight. It can be said that aircraft flight safety and meteorological elements have a close relationship between the Air Traffic Authority Meteorological Center issued by meteorological information and real-time meteorological information service is timely, effective, complete and accurate to the aircraft safe flight has a direct impact. Therefore, this paper focuses on the analysis of the meteorological elements that affect the flight safety of aircraft, and gives some suggestions to provide reliable guarantee for flight safety of aircraft and reduce the probability of flight accident.

Low generally indicates that the cloud bottom with the ground between the height of less than 2500 meters in the clouds, in particular to cause the Air Management Department to note that when the cloud bottom with the ground between the height of less than 300 meters of cloud, its flight to the aircraft is the most influential. If the cloud at the airport is exceptionally low, then the aircraft in the lowest security altitude of clouds or clouds flying, will cause pilots can not see the details of the ground, and then the plane could not land, if at this time forced landing, it is particularly easy to lead to the occurrence of flight accidents, the life of the passengers on board the safety of the threat. At the same time, sometimes in the low will also appear cumulonimbus, the cloud body with a particularly strong updraft or sinking air, but also often appear lightning, bumps and ice, and so on, seriously hinder the plane's normal, stable flight, so the cumulonimbus is generally used as a flying "restricted zone", Airplanes need to be as far as possible with this kind of halo to maintain a certain distance. If the pilot improper operation, mistakenly into the cumulonimbus, there is likely to be a serious flight accident, light damage the aircraft, the heavy machine destroyed the dead.

Thunderstorms are often accompanied by strong gusts of wind, storm and torrential rains, and sometimes hail and tornadoes, which have a particularly strong destructive effect on aircraft flying. During the thunderstorm, there will be particularly violent turbulence in the clouds and a vertical air flow, which can cause the plane to be bumpy, deviate from the original waterway, and can not effectively maintain the altitude of the flight, the stability of the aircraft operation is also seriously affected. Thunderstorms can also cause gust and wind shear, causing the aircraft to tilt phenomenon, serious will cause the fall of the road to fall off and a safety accident occurred. In addition, the aircraft in the thunderstorm weather, once the lightning attack, it is very easy to cause the aircraft some of the electronic equipment damaged, but also lead to the aircraft and the ground command system lost contact, some parts of the aircraft are magnetized, so that the magnetic compass error. At the same time, it is very likely to cause the plane's wings or other components to spark and discharge, to reduce the performance of the aerodynamic force, so that the ground control can not accurately determine and receive the aircraft flight information in time, can not accurately determine the specific location of the aircraft, which in some extent affect the role of traffic control, Poses a serious threat to flight safety.

Visibility is an important criterion for measuring atmospheric transparency, which is closely related to flight activity, and poor visibility is a serious obstacle in flight activity, which can increase the difficulty of flying and even threaten the flight safety of aircraft. Visibility is also a key factor in determining whether the airport is open or closed. Airports with poor ground navigation facilities are closed when visibility is less than 0.8 kilometres. When the impact on visibility is fog, precipitation, sand and other weather phenomena, the aircraft will be very difficult to achieve normal take-off and landing. In particular, the landing will have a great impact, if the pilot can not be in a short period of scientific and effective response, will trigger a flight accident.

For the ascent of the aircraft, Take-off, landing, flat fly and other operations, wind speed and wind direction will have a great impact on it. Generally speaking, the aircraft take-off and landing are wind, this is because of the state of the wind, the aircraft to obtain a greater resistance and lift, can shorten the operating distance of the aircraft. During Take-off, the aircraft will be able to get a larger additional intake under the upwind condition, thus providing for the maneuverability and stability of the aircraft. For Air flight safety, wind shear can have a great impact, resulting in a dynamic turbulence, at the same time, a different size of eddy current. This kind of weather phenomenon not only causes the airplane to bump, but also to the airplane take-off and landing the reliable, the security has the very big threat.

The formation of ice or frost on a plane caused by the freezing of water vapor in the air due to sublimation or supercooled water is an aircraft icing. When a plane encounters ice in flight, it will not only reduce the aerodynamic performance of the aircraft, but also increase the front resistance of the aircraft and reduce the thrust and lift of the aircraft. Aircraft in the ice will cause damage to the wing, increase the resistance in flight, so that fuel consumption rate increases. At the same time, it will cause the radio communication equipment and navigational equipment to malfunction and pose a great threat to the flight safety of the aircraft. If the ice is particularly thick, it will cause the plane's center of gravity to appear offset, affecting the stability of the aircraft, the operation of the aircraft has brought a certain degree of difficulty.

Once the aircraft encounter low, thunderstorm, low visibility, wind and ice, such as weather conditions, will have a serious impact on flight safety. Because most weather phenomena have the characteristics of timeliness, sudden and regional, it is difficult to forecast these weather phenomena in time and accurately. Therefore, we must strengthen the construction of these meteorological elements monitoring system, and effectively improve the accuracy and timeliness of these meteorological elements forecast. In addition, to improve the airport monitoring and early warning system, the full use of weather radar and other equipment to strengthen the airport meteorological elements of the monitoring, once there are some adverse climatic conditions, the need to timely forecast early warning, severe weather, it is necessary to temporarily close the airport.

The airport needs to increase the training of flight personnel, and constantly improve the overall quality of flight personnel. In the training, the flight personnel are required not only to strengthen the operational skills of the aircraft, but also to learn the knowledge of meteorological science, familiar with understanding the weather factors that often affect the safe operation of the aircraft, master its occurrence and development law. During routine flight training, crews should strengthen their flight training in complex weather conditions to improve the ability of pilots to cope with unexpected weather conditions. Pilots must strictly follow the relevant specifications required for operation, reasonable use of airborne radar equipment, through the visual, electronic compass and instrument data display analysis, determine the wind direction, wind speed and wind shear changes, at the same time pay attention to thunderstorms, ice, low, low visibility and other meteorological elements change trend, with the ground air pipe timely communication and communication, If you encounter a special situation, you need to report to the air traffic control command in time, and obey the command, take the measures of flying, returning, waiting and so on to avoid the threat of some meteorological elements.

Control personnel in the aircraft flight process to the meteorological Department in a timely manner to understand the weather conditions, the regional climate and dynamic changes, the estimated duration of the time must be mastered. According to meteorological forecast data provided by meteorological Department, we should observe the weather phenomena such as thunderstorm, Gale, low visibility and so on, and can use radar to understand the range and trend of these weather events. Control personnel to maintain communication with the Meteorological Department to obtain the latest information on the actual climate change, and according to the airport and the specific situation of aircraft flight, to develop a scientific and effective contingency plan, the flight of aircraft to make effective command, to maximize the safety of aircraft flight.

In a word, there are many meteorological factors that affect the safety of aircraft flight, including low, thunderstorm, low visibility, wind, and icing. In order to ensure the safety of aircraft flight, whether it is air management department or pilots must attach great importance to the monitoring of meteorological elements to enhance the accuracy and timeliness of meteorological forecasts, to provide reliable meteorological information service basis for aircraft flight. Flight personnel should strengthen training and learning, and constantly improve the emergency handling capacity of weather conditions. In addition, the Air Management department should pay close attention to meteorological information, conduct scientific and reasonable command of aircraft flight, and ensure the safe and reliable operation of the aircraft.
