Hi
When I load a flight plan, everything looks ok. The ins is aligned and set to nav, and works just fine. After TO I engage the auto flight system and auto throttle and the aircraft begins to follow the flight plan.
After a while the “heading ” light goes out, and the aircraft turn around and head  back in the opposite direction, and the  autoflight system can’t  be initialized again, This happens on all flights and I am out of ideas. Any help is welcome. The aircraft is one of the best looking in my hangar, and behaves basically really well, so I will hate to turn her into a hangar queen.

Kindly

Jakob

Problem solved
I was under impression that the nav button just above the alt selector on the NAVIGATION MODE SELECTION PANEL should be engaged together with the course button. That is NOT right. After some eksperiments I cracked the kode and when I only use the HDG  button, everything works smoothly. Together with flightplans generated by my atc program I must admit, that this product has, by far the best working autoflight system I has tried in any CS aircraft (and I has tried almost all of them). The L-1011 is now a joy to fly.

“Except that it says that the NAV Switch will be automatically deselected, while I think it really should say that you need to turn it off manually”

I agree. That confused me and I got it wrong.

But as I wrote: Everything is sweet now
