The RASAero aerodynamic prediction methods are the most accurate available for model, high power, and amateur rockets, and are of equivalent accuracy to professional engineering method aerodynamic analysis codes used for missiles, sounding rockets, and space launch vehicles.

In initial testing in comparison with high power rocket barometric altimeter, optical tracking, and accelerometer-based altitude flight data, 79.3% of the RASAero flight simulation altitude predictions have been within +/- 10% of the flight data, and 41.4% of the altitude predictions have been within +/- 5% of the flight data.

The RASAero aerodynamic predictions include drag coefficient at zero degrees angle of attack, drag coefficient with a non-zero angle of attack, and lift coefficient and normal force coefficient with angle of attack; for both power-on (thrust phase) and power-off (coast phase).  Center of pressure is predicted both as a function of Mach number and as a function of angle of attack.  Aerodynamic coefficients are predicted for the subsonic, transonic, supersonic, and hypersonic flight regimes, from Mach 0.01 to Mach 25.

The RASAero aerodynamic prediction methods and the RASAero software have been calibrated against NACA and NASA wind tunnel model data, free-flight model data and sounding rocket data, missile aerodynamic data, and professional engineering method missile aerodynamic analysis programs, against which in comparison tests RASAero has demonstrated equivalent numerical accuracy.
