What are TAFs and METARs?
A METAR report contains information on the current weather conditions of the facility releasing the report. It is released according to a regular schedule unless sudden or exceptional weather changes occur. TAF stands for Terminal Aerodrome Forecast.
What are TAFs in aviation?
The Terminal Area Forecast ( TAF ) is the official FAA forecast of aviation activity for U.S. airports. It contains active airports in the National Plan of Integrated Airport Systems ( NPIAS ) including FAA -towered airports, Federal contract-towered airports, non-federal towered airports, and non-towered airports.
What is METAR data?
METAR is a format for reporting weather information. A METAR weather report is predominantly used by aircraft pilots, and by meteorologists, who use aggregated METAR information to assist in weather forecasting. Raw METAR is the most common format in the world for the transmission of observational weather data.
What is a TAF report?
A Terminal Aerodrome Forecast (TAF) is a concise statement of the expected meteorological conditions at an airport during a specified period (usually 24 hours). Each ICAO state may modify the code as needed.
How do I decode military TAF?
The first three digits are the true direction to the nearest 10 degrees from which the wind is blowing. The next two digits are the sustained speed. If gusts are present, the next two or three digits following the “G” are the “gust,” the maximum wind speed in the last ten minutes.
Is Foreflight a legal weather briefing?
Pilots are creatures of habit though, and many continued to follow their instructor’s advice from decades ago that an official weather briefing had to be obtained from Flight Service to be legal, and a self-weather briefing was not legal.
WHO issues TAFs?
the National Weather Service Forecast Office
New TAF Format Our primary aviation responsibility at the National Weather Service Forecast Office in Brownsville is to issue Terminal Aerodome Forecasts (TAFs). Routine TAFs are valid for a 24-hour period and issued four times daily: 00Z, 06Z, 12Z, and 18Z, and are amended (updated) as conditions require.
Does Canada require ADSB?

Decoding a METAR
- PHNL = the airfield, Honolulu’s Daniel K.
- 250953Z = the date and time of the report.
- 05007G17KT = the wind conditions.
- 10SM = visibility.
- FEW024 / FEW040 = cloud cover.
- 27/19 = the temperature and dewpoint.
- A3001 = the atmospheric pressure, a.k.a. altimeter setting.
How far out do TAFs go?
TAFs are issued at least four times a day, every six hours, for major civil airfields: 0000, 0600, 1200 and 1800 UTC, and generally apply to a 24- or 30-hour period, and an area within approximately five statute miles (8.0 km) (or 5 nautical miles (9.3 km) in Canada) from the center of an airport runway complex.
What are the TAF data files based on?
These files are based on analyses that use TAF data. The enrollment data tables include data from calendar years 2016 through 2020. The service use data tables include data from calendar years 2018 through 2020. Both files include information for the 50 states, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands.
What is Taf’s impact in Washington State?

Every student is capable of achieving academic success, yet the public education system was not designed to meet students of color where they dream — instead they marginalize them and underestimate their abilities. TAF partners with school districts, educators, and organizations to challenge the current public education system.
What are the forecasts in the 2021 Taf?
In the 2021 TAF, forecasts of passenger enplanements and commercial operations at airports with more than 100,000 enplanements in FY 2019 are based on origin and destination (O&D) models of passenger flow. Forecast Process for 2021 TAF (PDF) — Summarizes the forecasting process
