METARS AND TAFS
 NOTE:  Atmospheric pressure reported for METARs is given in hectopascals (hPa), except in the United 
States, where it is reported in inches of mercury (in Hg).  Temperatures are reported in Celsius.
 NOTE:  METAR information is only displayed within the installed navigation databas\
e service area.
METARs	 (METeorological	 Aerodrome	Reports)	typically	contain	information	 about	the	temperature,	
dewpoint,	wind,	precipitation,	cloud	cover,	cloud	heights,	visibility,	and	barometric	pressure	at	an	airport	or	
observation	 station.	They	can	also	 contain	 information	 on	precipitation	 amounts,	lightning,	 and	other	 critical	
data.	 	 METARs	 reflect	hourly	 observations;	 non-routine	updates	include	the	code	 “SPECI”	 in	the	 report.			
METARs	are	shown	as	colored	flags	at	airports	that	provide	them.

TAFs	 (Terminal	 Aerodrome	 Forecasts)	are	weather	 predictions	 for	specific	 airports	 within	a	24-	 hour	 period,	
and	may	 span	 up	to	36	 hours.		 TAFs	typically	 include	forecast	 wind,	visibility,	 weather	phenomena,	 and	sky	
conditions	using	METAR	codes.
METAR	 and	TAF	 text	are	displayed	 on	the	 Weather	 Information	 Page.		METAR	 data	is	displayed	 first	in	a	
decoded	fashion,	then	as	raw	text.		TAF	information	is	displayed	only	in	its	raw	form	when	it	is	available
Displaying METAR and TAF text:
1) On the Weather Data Link (XM) Page, select the METAR Softkey
2) Select the RANGE Knob and pan to the desired airport.
