What type of weather reports are minimally required for departure or destination airports?

The correct choice involves METAR and TAF reports, which are essential for aircraft operations. METAR is an aviation routine weather report that provides current conditions at an airport, detailing visibility, wind direction and speed, temperature, weather phenomena, and more. This report is pivotal for pilots to assess the immediate weather conditions prior to departure or landing.

TAF, or Terminal Aerodrome Forecast, offers weather forecasts specifically for the areas around airports, usually covering a 24 or 30-hour period. It helps pilots plan their flights by predicting weather trends that could impact operations, including anticipated wind changes, precipitation, and visibility changes.

Both METAR and TAF reports are standardized and widely used in aviation for flight planning and operational safety, making them the minimal weather reporting requirements that pilots must consider when departing from or arriving at any airport. Other options, while relevant to aviation weather reporting, do not serve as the foundational reports that are specifically required for departure or destination airports.
