Just to see how this all fits together, there is a permanent offset of indication to the left because of the cold SAT.
If the average offset is 0.5R and 0.8 left how does that fit in the with 1.5 left and right maximum real deflection and the corresponding maximum value of rudder trim 1R and 2.3L.
Surely max indicated trim would be 1.5L+0.8L=2.3L (that makes sense and that's what's written in the FCOM)
But it doesn't make sense for the right 1.5R+0.5R=2?? (They say 1R)
How does that work?
