Possible bugs with the AP.
-
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.

@melon Yeah, at one point I got seemingly lost in one of the menus of the FMS; there, there was an option to authentificate yourself to Navigraph through the FMS; and if you proceed with that, Navigraph will ask you if you want to authorize "Working Title CJ4". :eyes:
If the FMS thinks it's a Citation, then maybe that explains why it does a terrible job at lateral navigation. Hope it will be fixed. -
@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.

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.

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.
