How to Calculate Air Speed

While all aircraft have a gauge that displays the airspeed, this number is not an accurate reflection of the plane's true speed as the plane's airflow pattern and a host of other variables all prevent an accurate airspeed reading. Online tools simplify the process by performing all of the calculations needed to determine true airspeed. All that is needed to calculate an aircraft's true airspeed is the altitude, indicated airspeed and the air temperature.
