What is the meaning of "VA" in a METAR report?

1. Volcanic Ash

2. Variable Altitude

3. Vertical Approach

4. Visual Assistance

The correct answer is: Volcanic Ash

In a METAR report, "VA" stands for "Volcanic Ash." METAR is an aviation routine weather report that provides information about weather conditions at airports and is crucial for flight planning and safety. When volcanic activity occurs and ash is present in the atmosphere, it can significantly impact aviation, leading to potential hazards like engine failure and reduced visibility. The inclusion of "VA" in a METAR report alerts pilots and air traffic controllers to the presence of volcanic ash, allowing them to take necessary precautions when planning flights or making operational decisions. The other options do not represent standard terms used in METAR reports. Variable altitude, vertical approach, and visual assistance are not recognized abbreviations within this specific weather reporting format, which focuses primarily on current weather conditions and hazards.
