In some ocasions the FBW A32NX doesn’t follow the flight plan specially in some SIDs and automatically the MCDU changes to heading mode and the waypoints of the SID disappear fromt the Flight Plan
It seems that when the MCDU doesn’t know to manage the flight plan then change to heading mode…this doesn’t happen in Xplane aircraft (Toliss, Zibo…)
Anyone has the same problem?
Thanks in advance
I use the FBW a lot, and never had that happen.
Obviously you are familiar with the A320, so it’s not a discontinuity in the flight plan.
What version of the FBW are you using?
Hi @PMaisanava,
I’ve moved your topic to the #third-party-addon-discussion:aircraft category which is more appropriate
Thanks!
The last development version…I use it a lot but I was wrong, its in STAR; nor in SIDs and its the flghy plan imported from SimBrief…GCRR to GCTS for example
I got the latest experimental version, but for some reason i cannot engage the autopilot anymore. It stops after a couple of seconds and then then i cannot engage anything from the fdu knows. Heading, speed, altitude, it won’t react to any input
A screenshot of your navigation display in PLAN mode would be really helpful.
In a STAR, there are sometimes purposeful MANUAL legs where the STAR ends and you need to go DIRECT to your approach fix. The A320 will go into HDG mode when it reaches the end of the STAR and you need to vector yourself to the approach like in real life (well, the ATC would vector you in real life, but let’s not speak of MSFS ATC here ). If this is what you are experiencing, you will see a MANUAL waypoint and flight plan discontinuity in the MCDU. Do you see this?
How do you import the plan?
Do you load the plan in the world map, or import through the ATSU function in the MCDU?
He’s used the Toliss from Xplane, so I believe he’s familiar with discontinuity, but you never know!
You should start your own post, rather than "highjack " someone else’s!
Haha i have no idea how it ended up here…

Import directly from ATSU menu, no discontinuities also, no manual waypoints, I use a lot Toliss, FFA320 using the same flight plan from SimBrief and all go perfectly!
Its true that Toliss and FFA320 are payware aircraft and probably their systems are better than a free Mod, I dont know…
I liked a lot MSFS 2020 but these issues turn me back to XPlane…
Thanks a lot for all your answers
I believe you need to manually enter your arrival runway, and star after you import the flight plan.
I enter the info while in flight, after I get a metar for the destination.
Normally I believe you would enter based on what ATC gives you for an arrival, but with this sims ATC, I don’t wait for that.
I suspect this may be what is happening.
Sevenflyer is right. If you aren’t adding your runway, approach, and STAR in the MCDU, you won’t have a complete flight plan. The FBW A320 will always revert to HDG mode if there’s no “next” waypoint active in the flight plan. Once you do add the arrival information, then you might start seeing MANUAL legs and discontinuities you will need to deal with.
The other time I’ve seen it give up on following waypoints is if the turns are too tight given your speed and it can’t calculate a path through the points.
Again, a screenshot would be super helpful. We’re just guessing.

I add the STAR and the runway…the flight plan is complete, Ive just tried the same flight plan in Toliss a319 now and all was perfect!!
Fbwa320 needs a lot of work yet
Thanks anyway
You should try the FBW Discord #Support channel. They can help as well. Although they will ask for the specific route and approach so they can check on their end. They’ve done this for me in the past. They will probably ask for a screenshot as well.
The FBW team has done a complete re-write of the FMS to be more realistic. It’s one of the most developed aircraft in MSFS right now, and their experimental version is testing out some more major enhancements.
I think its just what you say…usually happens in these quick turns in very close points…for example, when the flight plan is “easy” there are no problems, but when the STAR is a little difficult then the MCDU doesnt know to follow the flight plan and change to heading mode
I think this is because FBW doesn’t support VNAV yet…this doesn’t happens in professional aircrafts from XPlane…
No, it does not support Vnav yet.
My understanding of that is due to barometric issues in the sim itself.
It does follow Lnav very well.
I’m really not sure where you’re getting this from. I do LNAV flights that follow the flight plan perfectly, and so do 99% of users. VNAV is not related to this.
As asked by others, can you provide screenshots of your PFD and ND with managed heading ? This would help troubleshoot your issue a lot.
While this is not related to the topic of this post, this is not true. VNAV is not supported because it isn’t finished yet
My post was in answer to the poster’s statement two posts above your original post.
Do you know the reason it isn’t finished yet?
