The Operating Environment and Aircraft Performance Class, An environmental factor that affects aircraft performance is the air temperature and air density. These environmental factors can affect the forces acting on a plane; power, thrust, lift and drag. The temperature and density of air are directly related to the altitude as long as it is in the atmosphere's troposphere. The higher in altitude a plane goes temperature and density of the air will drop ( United States Federal Aviation Administration, 2016) Temperature is critical when it comes to aviation. Increasing the temperature of a substance decreases its density ( United States Federal Aviation Administration, 2016) Planes like to fly in colder climates. It is better for the airplane; it will not overheat due to the reduced temperature. An airplane in a colder location at sea level will perform a lot better than a plane 5,0...
