    Does it primarily happen on headings close to “heading north”? IIRC that was an issue on the CRJ also…

    It does indeed ! See, on both screenshots and on the video I posted - Heading north.

    @genista I'm currently flying North through France towards the UK. Real weather (and matching the OFP forecast really closely) without the swaying. I'll continue to monitor.

    I must say when comparing the 146 to the CRJ product from the other company, the 146 is far more polished at this stage.

    I also flew 2 sectors today (west/southbound) with no oscillations either this time. I suspect we need "strong" crosswinds for that to happen.

    I agree that this add-on is great, I do not regret my purchase at all. This little AP bug just ruins it a bit when it happens !

    Yeah, it definitely seem to be a northbound issue, right after it hits a waypoint it seems. Went and double checked my flights last night.

    have similar observation on two flights on this northbound segment AP started wobbling left right:
    central europe, west of LFSB ... [UN853;003°] LUL-GIVOR-SORAL
    on next segment [UN853;344°] SORAL-IBERA-DIK normal LNAV tracking
    solution: temporary switch to HDG.

    This was horrific to deal with tonight. It was fine right until TOD. Had to use HDG mode to get it on track but as soon as I tried LNAV again it did it again. It was only when I turned west on base did it behave again.

    This really needs to be fixed, it would make landing in a northerly direction near impossible when relying on the LNAV to guide you into range of the localiser.

    @genista Half the time my autopilot just blows through my waypoints in LNAV, I can see the needle change on the CDI but it doesn't follow.

    Yep. Just had the same. Blew threw the waypoint and started banking left and right aftewards. Wasn't even northbound this time.

    (don't mind the magenta line left of the waypoint - Volanta does not draw SIDs; Rikku waypoint was the first of my "normal" flight plan.

    Even a DIR in the FMS would not make it turn back on course.

    @genista Do you also have the Working Title CJ4 mod installed? I'm curious if there may be a conflict since the 146 uses a different version of that FMS.

    @mk316 negative ; No custom CJ4 installed on my setup.

    @genista Damn, had just disabled mine in hope of that possibly being the answer.

    @melon would be nice to get feedback from the devs. It's a proper bug.

    This code/logic is from the WT team and we're talking to them now to find a solution.

    @genista If it is any help, the CJ4 has the same issue.

    Also getting the same behaviour. -200, LNAV/FMS, northbound from YBCG. The weaving wasn't gentle, it was quite severe.

    I do seem to recall the weaving issue when the CJ4 was in it's active development phase but it did get refined to non-existence.

    Just on my 2nd flight using the FMS and I've not seen this symptom during either although the weather has been benign both times.

    I did however just have an issue departing 26L EGKK on FRANE1M where it did not make the 1st turn. It is more or less a 180 but at the speed I was going it should have managed. Once I threw a DIR to ACORN everything was rock solid.

    Just one anomaly so I wouldn't highlight as an issue yet - will monitor.
