Textual METAR/TAF Code
The current airport weather reports on the Textual
METAR page (and the airport weather forecasts on the
TAF page, too) use a rather cryptic format originally
devised for teleprinters. You can find information
about this format in an FAA publication, Aviation
Weather Formats: METAR/TAF, which can be down-
loaded from the FAA Web site.
You may see the following codes, which differ
slightly from the codes described in the FAA publica-
tion referenced above, at the start of a METAR on the
Textual METAR page:
• SA = METAR — a standard hourly METAR
report.
• SP = SPECI — a Special Report inserted
between regular hourly METARs to provide
late-breaking weather news.

TAF Page

When a GDL 69/69A is installed, the TAF (Termi-
nal Aerodrome Forecast) page is inserted into the WPT
page group, immediately after the Textual METAR
page.
This page shows a text message giving a weather
forecast for a particular airport. The format is similar
to that used for METARS, but describes a weather
forecast rather than current weather at the particular
airport.
