A320 vertical nav and the FMGC

Featured Replies

I understand that vertical navigation is not yet implemented, or at least not fully. But some questions - 

Once I have a flight plan loaded, along with a chosen flight level, when going to the Flight Plan page of the FMGC, on the left are the waypoints and on the right are the altitudes at each waypoint. Can these altitudes be edited in the Fly by Wire modded aircraft? As they appear on the Flight Plan page, they are not always accurate and can even show a different cruise level to that which has been selected during initial set up. Theoretically that would mess up fuel burn calculations amongst other things. Selecting the line select key adjacent the the altitude does take you to a new page but it seems there is no option there to edit altitude.

It also seems that the aircraft will decend to the next waypoint altitude at a rate that does not factor in the distance to that next waypoint? So you can end up at the next waypoint altitude way too soon unless you manually manage the decent using VS. Because of this the TOD marker is also usually indicating too early. Letting the aircraft decend under 'managed' mode from TOD will have you reaching the next waypoint altitude sometimes 30 miles early.

As far as I know, VNAV has not been implemented, and there’s not much you can do with the altitudes in the MCDU.

At this point, I’m using Sim Brief and Pilot2ATC to determine TOC and TOD, and managing my rate of climb and decent using V/S.

Not perfect, but it does the job for now...

Do you know if they are planning to implement?

They're working on their own autopilot and fbw code, aswell as flight model. So yes, they'll implement VNAV later on.

I've always wondered how this is handled in game.  I thought ATC gives you clearance at specific altitudes and you can't change altitudes until you get clearance to the next altitude.  So how does managed altitude work with the way ATC works in game.  Something's not sitting right because If I used managed altitude, ATC keeps harping at me to get down or climb to my assigned altitude.  

Do I have to look at my flight plan and keep manually asking for clearance to the waypoint altitudes until I reach TOC?  

And once at TOD, do I have to ask for lower altitudes as well?  

I've kind of given up wondering and just use selected altitude whenever I'm directed by ATC to change altitudes.
