Regarding recent stories about frost on a wing (NewsWire, Jan. 3):Often proven is the fact that an aircraft with hoar frost on its wing will fly in ground effect at a given airspeed, but upon leaving ground effect at that same airspeed the wing will be stalled. Due to the now-higher angle of attack, the wing will not unstall and a crash results.While one should not fly with a compromised wing, the wing can become somewhat compromised between de-icing and getting takeoff clearance.The answer, if one decides to go, is to provide a margin of safety: Keep the aircraft on the ground for extra speed, rotate more gently and have a solid amount of extra speed before leaving ground effect. While this procedure probably cannot be approved by officialdom, it works well and all pilots should at least least be aware of it.Doug Scott
