O.K. REAL LIFE time. When your butt is strapped into an aircraft on a short runway with trees at the end you had better pray for a cold day with the wind off the nose. I have 14 years of commercial flying experience in both hot humid Texas summers and cold Iowa winters, and for sheer performance of the aircraft I will take winter every time. Take offs and landings are shorter and climbs are amazingly faster. That is real life.
