An Equivalent Airspeed is calculated automatically along with the Free Stream Stagnation conditions.
The static conditions are picked up from the values calculated previously from the Atmosphere tab, within the Altitude pane.

The RAM conditions are calculated using the Isentropic relations, giving a ratio of free stream stagnation pressure to static pressure from the Mach number and Gamma
