These include placing the Pitot Static System at different altitudes and changing parameters such as Temperature, Station Altitudes, Station Altimeter Settings, and seeing how this affects the readings of the Altimeter and Airspeed Indicator. The Altitudes selected in the simulation are True Altitudes even though pilots don't fly True Altitudes so that it is possible to compare the indicated results with something more concrete and real. This is the same reason why airspeeds selected are True Airspeeds.
