What is the valid period for the TAF for KMEM?

The Terminal Aerodrome Forecast, or TAF, provides weather updates specifically for airports and is vital for planning flights. The correct answer reflects the standard forecasting period, which typically spans 24 to 30 hours.

In this case, the option that states the period from the 12th at 1800Z to the 13th at 2400Z indicates that the forecast starts after the initial period of the 12th and extends into the late evening of the 13th. This type of forecast duration is common, as it covers the necessary time frame for planning and operational awareness, ensuring pilots have access to current and upcoming weather conditions.

The other choices do not align with standard TAF periods: one provides an exact time without a clear extension into the next day, another lists a very specific short period that wouldn’t cover potential weather changes adequately, and the last option suggests too short or an unusual time frame, failing to meet the usual duration expectations for TAFs, which helps maintain safety in aviation operations.
