I fly heavies up in the high flight levels. What are my best visibility settings for high and low altitude maximum? I read the hints that say 70 and high as 80, is that the best for my type of flying? I cross oceans and long distance flying, so wondering what the best sweet spot for max vis would be. Thanks

Mine are at 70 and 80.

 

Mostly heavies here too but I never really change my settings anymore unless testing.
