What Does FG Stand For?
FG stands for Fog Metar Code
FG stands for "Fog Metar Code," which is a weather observation code used in aviation meteorology to indicate the presence of fog at an airport. This code is part of the METAR format, which provides essential information on current weather conditions for pilots and air traffic controllers. Fog is defined as a weather phenomenon characterized by a low-visibility condition, specifically when visibility falls below 1 kilometer (0.62 miles) due to suspended water droplets in the air. The FG code is critical for flight safety as it alerts personnel to potential hazards associated with reduced visibility during takeoff and landing.
