That's it!!!!! I am wasting no more time with this aircraft. Period.

Yesterday, I had it follow a route, loaded in the INS, albeit, a bit off the true alignment,but nevertheless, heading South towards its destination.

This evening I load the same FP same aircraft, same Rwy, etc, etc everything teh same. Did the same AP functions, and so maddeningly, the aircraft heads North.

Even re-checking the INS showed the FP loaded correctly and as per what it ought to be, yet the aircraft has a mind of its own.
