It would knock you out of the air most likely due to the rotory motion of the air under it. A heavy metal plane could but would get bounced around good. When flying mountail terrain and having to cross over ridges you set up your fligth path to cross them at a 45 degree angle to the ridge line and up here also you DON'T fly up a glacicer due to the cold air sink can be greather then your climb rate. Lot of tricks you have to learn to bush flying.
