Vorden

Ok I think I figured it out, I didn't realise you have to set the entire route ahead of time, like landing runway and everything, once I did that it seems to be playing nice. Certainly different from Boeing and CRJ FMSs for sure but that's why I'm doing this, to learn! Thanks for the responses.

I've followed the tutorial, I setup the FMS, I can see the altitudes on the legs page but whenever I press the VNAV button in flight, I immediately get "VNAV DISCONNECT" on the MCDU and the flight director switches to FPA. The autopilot IS engaged when I do this, other modes such as V/S work just fine. Any ideas why this might be happening or is this just a known bug? Thanks,
