I noticed today that when PF3 sets the NAV1 automatically for an ILS landing, its sets the runway direction to true rather than taking into account magnetic variation, which was 5 degrees different at EGJJ (263 instead of 268 if I remember rightly). I adjusted it manually.
Landing is not my best point (you wouldn't want to travel with me at the helm!) but for once I intercepted the ILS perfectly (none of the sweeping across it and swinging back to capture it that often happens) and plopped my wheels down right on the centre line. My grandmother would have been proud of me.
This may have just been a coincidence (perhaps because I haven't consumed any alcohol today!) but would it be possible to make PF3 set the magnetic course rather than true? To my simple mind, it should just be a case of inserting a small calculation into the code, I hope this wouldn't require a major re-write.
