What does the Tango designator in AIRMETs refer to?

The Tango designator in AIRMETs specifically refers to moderate turbulence. AIRMETs, or Airmen's Meteorological Information, are issued to provide crucial updates on weather conditions that may affect the safety of flight operations, particularly for smaller aircraft.

When a Tango is indicated, it alerts pilots to the presence of moderate turbulence, which can include conditions that are more than light turbulence but not as severe as what would warrant a Sierra or other designators for severe turbulence. The use of the Tango designation is essential for pilots to prepare for potential discomfort and challenges while flying, especially during takeoff and landing phases, or when operating in the vicinity of mountainous terrain.

In summary, recognizing the Tango designator as an indication of moderate turbulence is important for pilots to maintain safety and ensure they can make informed decisions regarding their flight operations under varying weather conditions.
