An existing theoretical description of the hot-film anemometer is reviewed to establish a quantitative basis for examining the effects of flow inclination on the velocity inferred with a typical anemometer configuration. The inclination effects are calculated with this theory and with an existing solution for the boundary layer on a yawed cylinder. It is shown that this probe configuration is sensitive to small angles of inclination and a 5 deg misalignment could produce errors of 30 to 45 in the inferred velocity. Author
