Why is the plane late?

Weather reason

At present, the weather is the main reason for flight delay. It is generally believed that the bad weather is obvious and passengers can understand the flight delay, but it is not.

At present, the explanation of civil aviation for the delay caused by bad weather is that the weather can not meet the flight standards and can not take off on time. General civil aviation service personnel often don't know exactly the impact of bad weather on flights like passengers. From the passenger's point of view: bad weather means strong wind, heavy rain and fog, planes may not be able to take off and land, and flights may be delayed. However, this understanding is one-sided and will lead to many misunderstandings. Think that civil aviation is deceptive, especially some flights can go and some can't.

The simple word "weather reason" actually contains many situations: the weather conditions at the departure airport are not suitable for take-off; The weather conditions at the destination airport are not suitable for landing; Meteorological conditions of flight routes are not suitable for overflight, etc.

In order to ensure flight safety, there are many meteorological standards that meet the requirements of flight, take-off and landing. Here, first of all, introduce where the weather conditions affect a flight, which will help you understand.

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

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

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

-Unit status (technical level of the unit, analyzing and mastering the current weather and trends to make professional decisions)

-the condition of the aircraft (the aircraft's safety standards for meteorological conditions and the failure of some airborne equipment on the premise of safety make the aircraft unsuitable for flying in such weather conditions)

-Subsequent situations caused by bad weather (mostly damage to airport navigation facilities and substandard runways, such as icing and serious water accumulation). )
