During initial training, one of the first flight planning skills a pilot must learn is how to access a weather briefing, closely followed by how to interpret the weather briefing. Among the things pilots must look for are factors that could potentially turn VFR into IFR conditions. It takes many forms, from low clouds, fog, and mist in the winter to smoke and haze in the summer. Any of these things make it more difficult for pilots to see each other in the sky.
Mist and Fog and Haze, Oh My!
What do mist, fog, and haze all have in common? They all reduce visibility in their own special way. The FAA has provided us with definitions of each in Advisory Circular 00-6B.
