Not sure why I'm posting this chart except to report that TO trim is so accurate across the range of CG and Flaps setting that a laserprint of the STAB Trim graphic is tacked on the wall right next to the Sim PC.. along with TO Vspeeds and triple LRC chart!!
While at it.. have a look at the LRC chart with `sweet spots' highlighted across the GW scale!
What's that?.. it's in kg?.. oh, well just use rule of thumb for (x 2.205)
double the weight.. then /10.. double that.. and add it!! :)
p.s. having fun with Simulator as usual.. :)
