Hi all, I was following the tutorial and everything was going perfectly smoothly until I realised that instead of sticking to the 4500ft, my CRJ was climbing (reaching FL300)..., well that's only the first thing, bu then, I had the feeling that it was not following the route... F/D are on, AP is engaged, my alt button pressed, hdg 030 locked, then turning to 60° to intercept the route... But my issue is that he does not stick to the altitude I entered (and I can't find a alt intv button ) and yeah that is pretty much it... Am I doing sthg wrong? Thank you, Carlos
