Can the plane take off normally in foggy weather?

Planes can't take off or land in foggy weather.

The fog early warning aircraft can not take off, because it is not only difficult to take off and land, but also extremely risky due to bad weather and unclear vision. When taking off and landing, once the pilot makes mistakes in judgment and operation, the plane may run off the runway or be destroyed. Therefore, when the vision is affected in foggy days, airports and highways have to be closed, which will inevitably cause unnecessary heavy losses.

The visibility of aircraft take-off requires at least 600 meters, and the landing requirements of aircraft are even higher than the take-off requirements. Therefore, for the safety of passengers, the plane will only take off when the weather is seaworthy. Due to poor visibility in foggy days, it is difficult for aircraft to take off and land, otherwise it may cause accidents.

When the weather is bad or the pilot can't use visual judgment for reference, the pilot can rely on the instrument landing system to guide the plane to land nearby, that is, the so-called "blind landing", which is essentially the instrument landing system.

Six meteorological factors affecting flight:

1, precipitation

For pilots, rain has a greater impact. Rainfall will reduce visibility, making it more difficult for aircraft to observe the surrounding environment during flight. In addition, rainfall will also affect the friction of the runway and increase the freight volume. Therefore, when it rains, airlines need to take more safety measures to ensure flight safety.

2. Thunderstorm

The appearance of thunderstorms means that there is a complex and powerful airflow in the clouds. They will affect flight safety and cause the aircraft to be damaged to varying degrees. When a thunderstorm occurs, airlines must ensure flight safety through decision-making and communication. The air traffic control commission stipulates that aircraft passing through thunderstorm areas must avoid and bypass other routes.

3. Heat wave

Due to the imbalance of energy balance, high temperature will produce heat waves. Meteorologists warned that this situation may lead to many deaths and property losses, but the impact on aviation safety is also obvious. In high temperature environment, the engine may overheat, thus affecting flight safety.

4. wind

Wind is an important factor in flight operation and flight planning. Wind speed and direction will also affect the judgment of pilots and the decision-making of airlines. When the wind speed is too high, the pilot needs to adjust the flight plan. If the plane loses control due to wind speed or direction, it will face extremely serious safety problems.
