Oooh, here's a good one! There *are* no unit names for angles. Angles are unitless numbers. So to be strict, the SI unit for heading must be the radian. :) FWIW, angles and computers don't mix well (tan(90) == Inf and all that). YASim does all its math in cartesian space, and converts to angles only at the output stage. Here's one such bug I discovered recently: turn on the HUD, and enter a steady turn. When your heading gets near 0 or 180, the pitch ladder just disappears. Andy -- Andrew J.
