A32NX FlyByWire vertical constraints

is there a description of how to use the vertical constraints? FlyByWire has done a great job fixing all the issues, but i’m having trouble with the VNAV.

Sometimes it will follow the profile, other times no. Perhaps its just me not understanding on how to use it properly. I never had issues with the payware airbus in FSX, or the PMDG 737, 777.

No, it’s not you. the flight model is still very buggy.
FBW has done a great job improving what they can,
but this bus needs a lot of improvements from Asobo to make it respond similar to a real one.

Interesting note- I made a flight plan which only included the Departure and Arrival Airports. When in the A320, i put in waypoints and then added vertical constraints and it followed it.

This is only one data point so i’ll need to create several and see if it follows those.
