Which AIRMET describes moderate turbulence?

AIRMET Tango specifically addresses moderate turbulence, making it the correct answer. This type of AIRMET is issued for areas of turbulence that can impact aircraft that are not equipped for severe conditions, particularly affecting light aircraft and those operating at lower altitudes. It provides pilots with critical information to help them prepare for and navigate through turbulent air, enhancing safety during flight operations.

In contrast, AIRMET Sierra pertains to IFR (Instrument Flight Rules) conditions, such as widespread ceilings less than 1,000 feet and visibility less than 3 miles, while AIRMET Zulu focuses on icing conditions that can affect aircraft performance. AIRMET Foxtrot is not an official designation and doesn't correspond to turbulence, further clarifying why AIRMET Tango is the relevant choice for moderate turbulence.
