Gracious yes, that's quite a typo :) As you say, it should be fabs(az1) > 90, i.e 'do penalise this navaid if the heading difference is more than 90 degrees' Though this whole function was deemed slightly suspect when I mentioned it here a few weeks ago. Obviously right now the aim was to keep the existing behaviour. I'm getting more and more encouraged to write a set of course and bearing helpers to deal with the normalisation and differencing. I've lost count of the number of times I've seen the: if ( az1 > 180.0) az1 -= 360.0; if ( az1 < -180.0) az1 += 360.0; Idiom repeated in the code, and lots of classes already have helpers for this - the KLN-89b and Mk-VIII, for example. Maybe there's some standard ones in SimGear I haven't spotted yet?
