What does METAR stand for?

METAR stands for "Meteorological Aerodrome Report," but it is commonly defined as "Aviation Routine Weather Observations." This type of report provides essential weather information for pilots and air traffic personnel, including observations on temperature, wind direction and speed, precipitation, cloud cover, and visibility. METARs are typically updated at regular intervals (usually every hour) and can include special reports if significant weather changes occur.

The focus of METAR is to ensure that pilots have the most accurate and timely weather data available, vital for ensuring safety during all phases of flight. The use of standardized terminology in METAR helps to promote clarity and consistency in aviation weather reporting, making it easier for pilots to understand conditions at the airports they are flying to or from.

The other options presented do not accurately reflect the purpose or standardization of METAR reports in aviation. Understanding METAR reports is crucial for pilots since weather conditions significantly influence flight safety and performance decisions.
