A CFD methodology is presented as part of the RVSM certification for Bombardier's production aircraft. Among the many issues affecting RVSM are production aircraft's skin waviness in the area of the Pitot-static probes and the variation in the positioning of the Pitot-static probe itself, both of which are inherent to the manufacturing process. These variations affect the pressure readings of the probes and thus the altitude readings. This paper quantifies the effect of skin waviness on the Pitot-static pressures through CFD. For this purpose, inviscid flow simulations are performed using Bombardier's in-house code FANSC in order to predict these pressure/altitude variations of production aircraft. This paper describes the typical CFD issues such as the process of skin-mapping of each aircraft, generating surfaces and creating computational meshes, and performing the CFD computations.
