Then why can't passenger planes in China take off and land as long as it rains? Can passenger planes from some European countries, especially Russia, take off and land?

The plane can't take off under the conditions of visibility, low-altitude clouds, thunderstorm area and strong crosswind.

You can take off in rainy days.

The explanation of civil aviation for the delay caused by bad weather is that the weather can't meet the flight standards and can't take off on time.

The word weather reason actually contains many situations: the weather conditions at the airport of origin are not suitable for take-off; The weather conditions at the destination airport are not suitable for landing; The meteorological conditions of flight routes are not suitable for flying over and so on.

In order to ensure flight safety, there are many weather standards for flight, take-off and landing, as follows:

1. Weather conditions at the departure airport (visibility, low-level clouds, thunderstorm area, strong crosswind).

2. Weather conditions at the destination airport (visibility, low-level clouds, thunderstorm area, strong crosswind).

3. Meteorological conditions on the flight route (high-altitude thunderstorm area).

4. Condition of the unit (technical level of the unit, analysis and grasp the current weather and trends to make professional decisions).

5. Aircraft condition (under the premise that the aircraft meets the safety standards of meteorological conditions, due to the failure of some airborne equipment, the aircraft is not suitable for flying in this weather condition).

6. The follow-up situation caused by bad weather (mostly the airport navigation facilities are damaged, the runway is not up to standard, such as icing, serious water accumulation, etc. ).

In recent years, the management of Russian airlines is not strict, and there are many cases in which pilots violate the operating rules, resulting in many accidents.
