Hi JimWhat sort of trim setting do you have?What sort of weight do you have ... and is the CG within limits?At rotation, do you still have full thrust or has a lower thrust been commanded?I assume your joystick is properly calibrated in pitch?Cheers

You`re not saying anything about config warning, so I guess the trim is in the green area, and you`ve got flaps set, correct?Okay, check your aircraft load manager, see if you`ve got more cargo in the forward hold than in the rear? You have no influence on the distribution of the passengers, but if you`ve put more cargo in the forward hold than the rear, you`re nose heavy. I seem to remember a post here some time ago stating that the rear hold should be loaded more than the forward if they are both loaded at all.How do you rotate? You say nose rises only slightly. On the "rotate" call pull back on the yoke until the nose is approx 10 degrees up. (Note, on the -900 tailstrike is around 9 degrees, if I remember correctly). Once you`ve got positive rate, continue rotation to 15 degrees.Try to trim a little more up before starting your takeoff run, set the indicator to somewhere between 4 and 6. I tend to use 5 and a bit, and it works OK for me. Normally i take off with flaps 5, if I`m light I use flaps 1 on the -6 and -7.Cheers,Kjell.

Trim of at least 5 for anything approaching a decent load. Don't hesitate to use a setting of 6 for heavier.Hope this helps,

Hi Jim,Hmmm... that all sounds OK so I am not sure what teh snag is. Could you tell me what runway you are using.. what the temperature is, are u using an Assumed Temp and have you selected a derate on teh engines. Also what altitude are you at? It may be best if we have a voice chat. I use Teamspeak to give online tutorials so you might like to install it even if you don't have a mic you can type your question to me in MSN and I can reply with a decent explantaion that does wear the flesh of the end of my finger :-xxrotflmaoAll the Best,

hi brad the runway was the default in fs9, i did not put a temp in the fmc i was following the advanced tutorial by timothy metzinger {lesson 4} a engine derate was selected with climb 2 i also set a flight today with 100% fuel in the wing tanks and 50% in centre tank flaps 5 trim in green area i also used fdc and followed the callouts i was able to take off, i think i maybe set the fmc up incorrectly in the tutorial. if i keep having this problem i will get back to you on msn. i have only had the pmdg 737ng for a couple of weeks and am really impressed with it i have a lot to learn and am willing to take the time to do so. i like to thank you and everyone on this forum for taking the time to reply to my queries. thanks jim mcpherson
