My husband writes: A flight demonstration team such as the Blue Angels fly, depending on the position of the diamond formation, with full trim out of the formation. That is the left wingman flies the entire flight with full left trim and perhaps full down trim - so that if the pilot lets go of the control stick, the plane will abruptly roll to the left and downward away from the formation. Likewise the right wing would roll down and to the right. The slot pilot - the one in the back, trims full down,so that the plane will dive away from the formation. That is an extreme amount of pressure (that is force) on a single arm for the entire flight. Trim means that you are holding against the force of wind pressure on the control surface. If you are out of “trim” the pilot has to hold against the wind forces on the control surfaces for as long as the control is out of trim.

Thanks to you and him for that - much appreciated!
