BACKGROUND

Each Terminal Aerodrome Forecast (TAF) is valid for a 24 or 30 hour time period and is updated four times a day at 0000Z, 0600Z, 1200Z, and 1800Z. A TAF can be either a routine forecast (TAF) or an amended forecast (TAF AMD). The date and time of origin are given in a six-digit group with the first two digits being the date and the last four the time in UTC, followed by the valid period group. The forecast then lists wind, visibility, significant weather, sky condition, and change groups.

STUDY TIP

Memorize the four synoptic issue times six hours apart. Pair this with the valid period lengths of 24 or 30 hours.

KEY POINTS

  • Scheduled TAFs are issued four times per day.
  • Issue times are 0000Z, 0600Z, 1200Z, and 1800Z.
  • Each TAF is valid for 24 or 30 hours; TAF AMD marks an amended forecast.
