I have an insurance checkout today in the venerable Cessna 150. Severe clear, light surface winds, but 35 knots at 2,000 and calling for wind sheer. Aside from the fact that cars on the road will be passing me when flying into the wind, I've never really dealt with wind sheer. My instructor has always told me that 25 knots or greater at 3,000 feet generally means turbulence and wind sheer, and frankly I've generally just avoided it. Is 35 knots at 2,000 reason to bag a flight in a 150? Aside from having mo experience with it, I'm wondering if hose are ideal conditions for getting acquainted with a new plane.
