AP can't lock onto FMS path after sharper turns

Hi all,

I was wondering if I am doing something wrong, but on sharper turn the AP can't follow FMS very well - it happens on sharper turns after which it tries to correct its course but constantly oversteers left and right resulting in a zigzag shape - it sometimes creates issues on approach via localizer. Any insight?

Regards,

Jeremy Smirnov

I have this issue sometimes and it has been reported a fair bit. Not sure what the devs ended up doing about it.

Assuming these are similiar issues? viewtopic.php?f=105&t=12317

Indeed it is the same issue. There will be an adjustment to it's handling in the future. I don't have an ETA for you right now though. I would suggest using heading select mode maybe if you see you have a very sharp turn coming then resume FMS navigation once you are stabilized.
