What should I do if I encounter a thunderstorm in Captain China ?

What hazards can be caused by lightning is common sense knowledge that we need to know in our daily life. It is understood that thunderstorms are a dangerous weather condition that endangers the safety of aviation flights, so in general, flying in thunderstorm zones should be avoided. So what should you do if the plane encounters a thunderstorm?

Today, Baibai Safety Network will take you to learn about these natural disaster safety tips.

First, before the flight, the flight personnel should carefully learn about the weather conditions in the flight area from the meteorological department, especially for the areas that may produce thunderstorm weather, they should carefully study the nature, location, range, intensity, altitude, moving speed, and change trend of the thunderstorm, and at the same time take into account the orbiting plan and precautions.

Second, as long as possible, the pilots should avoid the thunderstorm activity area as much as possible, and the methods are to postpone the take-off time, change the route and flight altitude, wait in the air, fly around, change the landing, and return home.

The third is to use airborne radar to monitor weather changes during flight, and when the echo of cumulonimbus clouds is found, we should constantly pay attention to its intensity changes.

Fourth, when flying around a thunderstorm, the basic principle is not to enter the thunderstorm cloud visually, and strive to fly on or outside the cloud. When orbiting, it should pass more than 25 km from the edge of the radar echo according to the intensity of the thunderstorm. Be cautious when crossing the gap between two cumulonimbus clouds to prevent passing between the two strong echoes.

Fifth, try not to fly under thunderstorm clouds, because lightning strikes (lightning strikes) between clouds and the ground are the most frequent, and aircraft are also the most vulnerable to lightning strikes (lightning strikes). If you are flying under clouds, try to avoid isolated hills, large trees, towers, and spires of tall buildings.

Sixth, when flying in the clouds, the weather encountered is complex and changeable, and it is necessary not only to judge the situation according to the on-board radar, but also to request the ground radar to cooperate and obey the command of air traffic control.

Seventh, try not to fly in the precipitation area above moderate intensity, the reason is that it is easy to be struck by precipitation electrostatic lightning (lightning strike); Second, precipitation has a certain attenuating effect on radar echoes, so we must be cautious.

Eight is when there is a thunderstorm at the take-off airport, usually do not take off. If the thunderstorm is weak, the task is urgent, and there is the possibility of flying around, you can take off in the direction of no thunderstorm; When there is a thunderstorm at the landing site, it should generally fly to the alternate landing field. If the task is urgent or the fuel is insufficient, you should find a favorable direction to land; When there is a thunderstorm in the corridor, it should take a detour or climb to overtake, and take off or land after ascending over the airport; Special attention should be paid to the effects of wind shear when taking off and landing from airports at the edge of the thunderstorm zone.

Finally, in the thunderstorm season, when the aircraft is parked, it is necessary to do a good job of protection, connect the ground wire, and do a good job of preventing the aircraft from thunderstorms, winds, hail, lightning and lightning strikes on the ground.

As the largest metal object in the sky at present, the aircraft will be directly exposed to lightning, strong wind, and heavy rain in thunderstorms due to the limitation of objective conditions in flight, and in this case, it is difficult for the aircraft to avoid the attack of thunderstorms. At the same time, thunderstorms mostly occur in the air ten to twenty kilometers above the ground, and the position of the aircraft is exactly at this altitude when taking off and landing. At this point, the aircraft will become the first target of the thunderstorm.
