It snows in Changsha. Does the airport take off as usual?

Civil aviation depends on the weather. It is impossible to judge whether the plane can take off only by the lack of snow, but also involves many aspects.

It was also the weather that caused some flights to be delayed, while others were told that they could not leave because of the weather.

There are several reasons for this.

The influence of the weather or route of the other side; Different flight routes; If it is a wet lease aircraft, it is necessary to implement the aircraft, crew and operation standards of the other party; For safety reasons, reduce return flights; In view of this problem, the competent civil aviation administration has a unified operating standard, but this standard is the minimum standard, and airlines will formulate their own standards accordingly, which is higher than or equal to that of the civil aviation administration.

In addition, when the weather conditions of the other side are unstable, sometimes good or bad, and in marginal weather, and the flight location is the base of these airlines, some pilots are familiar with the climatic conditions there and have rich experience, so when the flight is delayed due to weather reasons, they may choose to try to take off when the weather turns better; If weather conditions permit, the flight will land; Once the attempt is unsuccessful, most of them will not choose to return to the airport, but take the alternate airport. In both cases, there are further delays and security risks.

Sometimes, it is because the weather conditions are really not up to the company's flight standards. Every airline sets its own flight standards according to the flight standards in different regions, which is one reason why some airlines can fly instead of flying.
