What is a METAR used for?
METAR is the international standard code format for hourly surface weather observations which is analogous to the SA coding currently used in the US. The acronym roughly translates from French as Aviation Routine Weather Report.
What does the term METAR signify?
Definition. Meteorological Terminal Air Report (METAR) – literally ‘Meteorological Terminal Air Report’ or more straightforwardly ‘Routine aerodrome meteorological report’
What does METAR contain?
METAR contains a report of wind, visibility, runway visual range, present weather, sky condition, temperature, dew point, and altimeter setting collectively referred to as “the body of the report.” In addition, coded and/or plain language information which elaborates on data in the body of the report may be appended to …
What distance does a METAR cover?
An automated METAR with no human supervision covers the conditions within approximately 6 inches of the weather station reporting it (for example, a badly positioned AWOS/ASOS station may be shielded from wind in some directions which affects what it reports).
Are Metars in AGL?
pilotod Pre-takeoff checklist METAR is AGL and so is TAF.
Can you fly VFR in Broken clouds?
Cloud layers, of whatever type, are always given with altitude of the bottom of the layer, measured in feet AGL. The last two cases, broken and overcast, describe a cloud layer that may not be penetrated in VFR flight. The bottom of such a layer constitutes a ceiling for VFR flight.
How are Weather Codes used in a METAR?
The weather portion of the METAR is heavy on code use. Codes are used to relay intensity, descriptor, precipitation, and/or obscuration information. For a complete listing of weather codes that can be used for both METARs and TAFs, review the TAF decoder courtesy of the Aviation Weather Center.
Is it possible to read a METAR report?
A METAR contains large amounts of valuable information condensed down into a very concise report format. The report is comprised of blocks of coded data separated by spaces. To read a METAR, you will need to learn the 11 different parts, what information is included in each, how it is formatted, and what codes can be used.
What does the next four digits in METAR mean?
The next 4 digits 0136 refers to the time when the report was made. The Z refers to ZULU or UTC time. Sometimes the METAR will have a COR or AUTO modifier after the Date & Time. COR means it is a corrected report and AUTO refers to an automated station.
Is it possible to auto translate a METAR?
The remarks section of a METAR is not always used, but when it is, it is often regarded as the most difficult to translate. Aviation weather apps do not usually auto translate it, and there are so many possible information types and codes that it is nearly impossible to memorize them all.
