This is relevant to the discussion (thanks, Google): http://flighttest.navair.navy.mil/unrestricted/FTM108/c2.pdf Here's an excerpt: Errors in total pressure caused by the angle of incidence of a probe to the relative wind are negligible for most flight conditions. Commonly used probes produce no significant errors at angles of attack or sideslip up to approximately 20°. With proper placement, design, and good leak checks of the pitot probe, zero total pressure error is assumed. If any of the engineers on the list want to read all 89 pages and distill it down to something I can actually use, I will be very grateful.
