VOLMET

VOLMET (VOL Météo) is a worldwide meteorological broadcast service for aircraft in flight. It provides current, routine weather reports (METARs) and trend forecasts (TRENDs) for selected aerodromes. VOLMET broadcasts are designed to give pilots up-to-date weather information to assist with flight planning and decision-making during a flight.

VOLMET broadcasts are typically transmitted via High Frequency (HF) radio, Very High Frequency (VHF) radio, or via data link systems. The specific frequencies and aerodromes included in a VOLMET broadcast vary depending on the region and the specific needs of the aviation community in that area.

Pilots use VOLMET broadcasts to:

• Monitor en-route weather conditions.
• Obtain weather information for their destination airport.
• Assess the need to divert to an alternate airport.
• Make informed decisions regarding flight parameters, such as altitude and speed.

VOLMET information is time-sensitive and is updated regularly, often hourly, to reflect changing weather conditions. Pilots should always consult the latest available VOLMET broadcast before making critical flight decisions. Aviation authorities and meteorological agencies are responsible for the creation, maintenance, and dissemination of VOLMET broadcasts within their respective jurisdictions.
