Pilots fly under instrument conditions all the time, but then again, they have a bit more margin of error, unless they are landing.
OK, it's not exactly about skiing, but if you do any driving in the mountains in the winter, sooner or later you're gonna have one of theose white-knuckle trips.....
With good reception of 4 or more satilittes and a WAAS enabled GPS you are golden within 3 meters. Then you got the GPS update time vs speed you are traveling. I guess I wouldn't do it and I hope you are never on the same hiway the same time as me if you do it.
That being said, I have a friend less than 2 wks ago flew his Cessna 150 over(through) Parley's Pass following I80, He was ferrying it from the midwest to SLC, he was VFR, but had his GPS showing right over I80. I talked to him on the phone after he got there, said all he could see was mountains all the way around him, he was less than 2000 ft AGL (a little over 10,000 ft MSL) and short on power to go higher. Quite a trip, but a permanent move for him.
He was skiing at Solitude last Sunday!
