Trim in autopilot at cruise alt

Featured Replies

Hi,I'm still learning my ways with 737NG and I have probably silly question. When I reach cruising altitude and use autopilot to fly my programmed route the airplane is never properly leveled. Its nose is always more then 2.5 degrees up. Is there any way to correct this problem? If so, how to do it? Thanks for all replies,Szymon (N737AN)

There is nothing to *fix*. The aircraft does not fly level like you think. This is varied of course on a number of factors all too many for me to type here but it is correctly modelled..Best Wishes,[h4]Randy J.

Randy is quite right tha aeroplane always has a slight nose up angle in the cruise.Try an experiment. Climb a few thousand feet level off with autopilot engaged and autothrottle in say 250kt. Check the pitch when stable then reduce speed on the flap speed schedule. Lower the flaps one setting at a time and watch the changing pitch angle. Stabilise at the manoeuvering speed for each flap setting. Remember you are still flying level. Make a note of the various flap setting pitch angle combinations. When flying manually these will be good ball park pitch attitudes to aim for when in different configurations.Also check the power settings required in each configuration. Again only ball park figures as obviously your power setting will alter with aircraft weight. What it does do however is to give you datums to which you can refer and will save you hunting aimlessly for pitch and power settings.RegardsChrisY

ChrisY,I've been aviation fan all my life (started in model making at age 10) - no wonder with father in the Air Force. So I know quite a lot of theory (and new the nose up angle on flaps), but right now my knowledge seems rather thin after trying to learn some serious commercial aviation (a simulator but I don't think it gets any more real). I printed all neccesary manuals from PMDG and VATSIM and I'm still reading them and learning as I go. Thanks to guys like you and Randy I can get my answers from real people and at times that manuals don't give any or good answers. It actually amazes me how much discussion goes on this forum and how serious and detailed that stuff is. Lots of learning but lots of fun as well. And try to explain non-flying people it's not just a stupid game.Thanks again,Szymon
