G'day Old Farang......we get brown-outs - big time
white-outs from powdered snow also happens, but depends on the condition of the snow (fresh powder or slushy or crusty)
Brown-outs are easier to manage cause You can usually peg Your eyeballs to a rock through the chin bubble for a reference
powdered snow is more tricky; throw out a backpack on a flypast to help avoid flat-line effect & drive the toes in before You loose visual, need some head wind to keep ahead of the fluff
anyways no-fun
