Simulation "Airspeed Indicator"
This simulation shows how the Indicated Airspeed (IAS) changes with the increase of the flying altitude. To find the True Airspeed (TAS) you use the scale which is incorporated in the Airspeed Indicator. You have to correlate the flying altitude with the Outside Air Temperature (OAT) in the upper scale of the Airspeed Indicator. In the lower scale you will find the True Airspeed (TAS).
