What is the minimum surface wind speed required for an AIRMET Tango?

The minimum surface wind speed required for an AIRMET Tango is 30 knots. An AIRMET Tango is issued to advise pilots of moderate turbulence and strong winds that may affect aircraft operations. This type of advisory is particularly important for general aviation pilots who may not have the same level of experience or equipment as commercial pilots to handle such conditions.

The threshold of 30 knots signifies the point at which wind conditions are considered significant enough to warrant caution. Wind speeds below this level typically do not present the same level of risk and would not justify an AIRMET. Thus, when pilots receive an AIRMET Tango, they are alerted to take extra precautions, as winds at or exceeding this level can lead to turbulence that could affect safety and performance during flight. The focus on this specific wind speed helps in ensuring that pilots are well-informed and prepared for potential challenges in flight operations.
