0.5 takeoff trim recommended setting in FMC

Has anyone else experienced the 767's fmc recommending a 0.5 takeoff trim setting?  I know I am correctly programming the FMC with all the proper weight and balance info, so I don't know why it is doing this.  I just go ahead and use a trim setting in the 2.5 to 2.7 range, but this is not very accurate.

Yep. I have. It's always been like that since v1.0. It is a pity that it isn't more like the 757s.

I always set the trim to 0.5 and unlike the 757 it doesn't seem to lift off at V2 like the 757. It's always a bit later. If I set the trim higher than 0.5 the 767 wants to climb very steep at about 6000fpm. I also think that the range of 2.5 - 2.7 would be more realistic but I don't know if that would true of the 767 either. Sad

I experienced the opposite when I tried 0.5.  The aircraft required immediate positive trim and backpressure on the yoke to keep it from descending. Huh

Guys,

These trim setting numbers you are suggesting,... do you go by the hash marks or do you go by the numbers that appear if u leave your mouse pointer on the trim gauge for a second?As you know they DO NOT correspond at all!

I go by the Cockpit Tooltips that display for a few seconds when you hover the mouse over the trim lever. That works well for me.  Smiley
