Re: How to tell how thick the fog is...
I often use my plotter cursor to a known object I can barely see..
Like here where we could almost make out this island if we looked closely. As you can see we are at about 411 feet away so roughly 400 feet of vis.
That also shows how good it is to have the radar overlay on top of the chart platter. Very nice.
