Think about what this means to the lateral trim situation.!!!
NO Lateral Trim.
NO tendency to return to wings level. You must fly the roll angle full time.
Yes you have enough roll authority to level the wings.
You cannot let go of the stick-It will roll.
Do you see how a guy settling into this situation might apply nose up at the same time???
If not, do this experiment:
Place right arm on table in front of you. Point thumb up.
Put a stick in hand. Tilt stick to left.
With opposite hand, resist the attempt to tilt stick. Do you accidentally tilt stick toward you?? If not, apply more force until you have to cup stick in hand instead of with finger tips.
Get the idea?
All fair points.
Firstly, was the aircraft right-wing heavy?
Secondly, I can see how it would be a handful, but the force we're talking about here is not an accidental tweak in the wrong direction. To get the THS up to 13 degrees requires full back pressure for several seconds. This is the problem that is not going to be solved until at least an interim report is out, and anything we suggest is ultimately pointless.
Thirdly, I couldn't get your experiment to work - would the fact that I am left-handed be a problem there?
