Hi all ,Right now I'm flying A340-600 at 35,000 FT but the airplane nose is "up" how can I make it fly straight?
take a look at this pick:
That is correct. Aircraft don't fly in a completely level attitude especially at high altitude. Approximately 5 degrees nose up is normal and realistic.
You're probably too heavy for your altitude. Try descending a bit to lose some fuel and then climb again - thats only if you're near 10 degrees pitch up attitude though.
Also, if your aircraft is cruising too slowly, the aircraft will pitch upwards to provide necessary lift.
