At 9,000 feet, the 180-horsepower Lycoming engine in a Cessna 172 makes only about 130 horsepower. Thinner air at this altitude prolongs takeoff rolls, diminishes climb rates, and can add 10 to 15 knots or more to a trainer’s true airspeed on approach. Heat amplifies the effects of altitude, making Lake County Airport (LXV) in Leadville, Colorado, inaccessible to many aircraft by midday.
