Part Two: Section 2 XM Weather 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 downloaded from the FAA Web site. You may see the following codes, which differ slightly from the codes described in the FAA publication 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 (Terminal 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. TFR Information Areas with TFRs (Temporary Flight Restrictions) are shown outlined in yellow on the NAV main page of the 500W-series and on the Map and XM Weather page of both the 400W and 500W-series. More information about Temporary Flight Restrictions can be seen on the TFR Information page, which can be accessed from the Map page or the XM Weather page. 1a.

Then, turn the large right knob to highlight "Show Map Pointer" and press ENT to bring up the map pointer. 2. Turn the large and small right knobs to move the map pointer to the yellow boundary of a TFR region. When the map pointer is within the TFR region, its boundary will be highlighted with a wider yellow line. 190-00356-30 Rev H 19

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.

TFR Information

Areas with TFRs (Temporary Flight Restrictions)

are shown outlined in yellow on the NAV main page

of the 500W-series and on the Map and XM Weather

page of both the 400W and 500W-series. More

information about Temporary Flight Restrictions can

be seen on the TFR Information page, which can be

accessed from the Map page or the XM Weather page.

1b.

With the XM Weather page (the third page

of the NAV page group) displayed, press the

key to bring up the Page Menu. Then,

turn the

large right

knob to highlight “Show

Map Pointer” and press

ENT

to bring up the

map pointer.

Turn the

large

and

small right
