... easier said than done !
Hi gents,
looks like one needs to do some tweaking here ...
Because (said of aircraft performance file parameters):
a) TrimMin and TrimMax relate to the green band of the EICAS trim gauge;
b) TrimScaleMin and TrimScaleMax relate to the same reality (which - I guess - is more visual than operational);
c) Then the value from the CDU appears to be the one to be trusted.
I fly a PMDG 737-700, and the perfomance file for the CDU (Steve Reyling's, made available for d/l from PM site) has these values:
TrimMin=2.1
TrimMax=8.75
TrimScaleMax=17
TrimScaleMin=0
which look quite correct ...
Last night, though, I had my EICAS elevator trim gauge showing 8.3, whilst the CDU trim showed -0.30.
Needless to say, it's the latter which must be trusted: I couldn't get the a/c rotate and lift up with a "nominal" 8.3 on the EICAS, since it actually was a -0.30 ... and until I brought the latter towards 4.00 (and that was more than 12 on the EICAS, which is hyperbolic) I couldn't take off.
Therefore the advice I have is to calibrate the values I described (TrimScaleMin / Max) to your needs. May be a higher value for max.
This settings depends on FS and the used A/C.
More fly-and-try will tell us more ...
:roll:
Ciao a tutti,
