Just brushing up on my aviation knowledge here.
In Everything Explained for the Professional Pilot it describes the TAF as having a 5 nm radius. However, I believe the AIM says 5 sm.
Anyone have an AIM handy that can help out?

7.2 Terminal Aerodrome Forecast (TAF)
A Terminal Aerodrome Forecast (TAF) is a concise statement of the expected meteorological conditions significant to aviation for a specified time period within five statute
miles (SM) of the center of the airport’s runway complex (terminal). The TAFs use the same weather codes found in METAR weather reports (Section 2) and can be viewed on the National Weather Service (NWS) Aviation Digital Data Service (ADDS) web site at: http://adds.aviationweather.noaa.gov/tafs/

Terminal Aerodrome Forecasts (TAF)
A TAF is a report established for the five statute
mile radius around an airport. TAF reports are usually given for larger airports. Each TAF is valid for a 30-hour time period, and is updated four times a day at 0000Z, 0600Z, 1200Z, and 1800Z. The TAF utilizes the same descriptors and abbreviations as used in the METAR report. The TAF includes the following information in sequential order:
