Possible bugs with the AP.

@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.

Genista

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

Melon

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

Genista

@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.

Good to hear, thanks for the feedback !

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

Melon

@martyn Awesome thanks! Its pretty painful to deal with and will be great when it's fixed.

@Martyn Can confirm this issue today as well.

Routing: KPDX DCT BTG J1 SEA DCT PAE GRIZZ7 CYVR

LNAV (using FMS)

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.
