vilas, that is a great point. With the myriad of equipage possibilities and combinations of systems being used, it is very difficult to determine all of the possible issues that could occur. As noted many times, the Ge box and Honeywell box use completely different internal methodologies for location, especially in turns, and all are different than the procedure design software!
Prox warnings are another one, again with the different manufacturers using different values in the final segment. (HW 500' ROC and HW a 400' ROC at the FAF)
Had a hell of a time when one airline started using the RC system, it just could not understand fly-by waypoints and the constant descent profile, always porpoising down to a level segment after crossing the waypoint.
So, yes, please do report any anomoly, with as many parameters as possible that created the situation.
