LDS is currently working on a 757 and *THAT* one I am eargerly awaiting as it will be the pinacle, the benchmark for 757s.

Now that Captain Sim is out I think they'd be better off doing a 777 or something... I didn't really even know they were still working on that. When I frequented their forums you weren't allowed to talk about it something like that.

Tim,In real life the CG of this old lady is between 32 and 40% depending on the load.5.75 up trim will never been used because of the risk of tail strike :--)I have noticed that the CS757 is much more accurate than other heavies regarding CG/trim adjustment and it seems that their algorithms are pretty serious on that point.

I have started to figure out that 5.75 trim is bad, because the first thing I have to do is wildly trim nose down after takeoff to maintian any kind of reasonable climb attitude. Also troubling is the airplane taking off the runway by itself and not letting me rotate. I suspect a proper CG / Trim would solve all of these issues, and perhaps others.If they're so accurate, why is it such a secret? ACE doesn't give you your ZFW, much less CG. Your weights have to come off the sim Fuel/Payload page anyway because there is a variance. So what's the answer in your opinion?

Good question Tim and unfortunately I don't have the answer.I am not sure it has something to do with keeping a secret but rather a bad codification of ACE togeher with a bug in the FMS.(When you enter a 40% CG the FMS gives you a trim of 1 which is wrong)What I have noticed is that the aircraft attitude during TO is really dependant on the CG/trim parameters and those reflect reallity:With default cargo and 50% fuel the most realistic combo is 40% CG and 4.5 trim like in the real thing.Give it a try :-)

David, what do you consider "default cargo?" ACE presents me with a tabula rasa every time, and I have to fill up the empty seats and load the cargo to whatever weight I want.Tim
