What is the minimum number of factors affecting the takeoff of aircraft due to wind and rain?

First of all, you must know that different aircraft types (big and small), different captains (high and low skills), different airports (blind landing navigation equipment have good and bad), the required take-off weather standards It's different.

Rain has little impact on takeoff, mainly on visibility. The minimum runway visual distance standard is generally 400 meters. If it is less than this, takeoff and landing are not allowed.

Thunder has an impact on aircraft takeoff and landing. Lightning strikes can cause damage to aircraft components, and aircraft exceeding the standard cannot be released.

Wind has a great influence on aircraft, including wind speed and wind direction. For example, wind speeds greater than 65 knots can cause damage to an aircraft's open door. The angle between the wind direction and the runway is important. Crosswinds can cause the aircraft to deviate from the runway. Then there is low-altitude wind shear, which is an aircraft killer. These airport meteorological departments will forecast it.

One more thing, the weather at the departure and destination airports is very good, but the plane may not be able to fly! Because there may be bad weather on the intermediate route. This is something travelers often don’t understand.
