Thank you ever so much Spanner Turner,
That's what I suspected and always thought. I was deep in the wiring diagrams yesterday trying to figure it out but I could not grasp when the A/P would infact trim at full rate.
The reply previous to yours was obviously out of a pilot's manual and they never tell you the truth.
I owe you a beer (or beverage of you choice, champagne not included)...
Cheers
