October 12, 200322 yr I doubt it very much since the autopilot will set elevators and trim to what it needs in order to maintain the flight profile. Try altering the trim, for example, and see what happens. The autopilot will fight against what you are trying to do.David

Airplane "must" be trimmed before setting the auto-pilot2- Some Auto-pilot's sense an out of trim condition & have a panel mounted warning light and/or audio warning.3- And some Auto-pilot's sense out of trim conditions & have additional servo's to manipulate the trim.Regardless of the auto-pilot simulated, I make sure my simulated aircraft is in trim before flipping the A/P switch on. Doesn't matter if it's trimmed for climb, cruise, or descent. Without actual stick forces, my "brain" senses out of trim conditions from sight & knowing what an out of trim--- real plane is like. This combination actually forms a sense of "feel" into my joystick with trim switches. An example is, adding up trim until I detect the simulated airplane slightly moving up, through the visual horizon, attitude indicator, and perhaps the VSI, then backing off a bit.When my plane is trimmed before setting the A/P, I find it doesn't have un-wanted surprises when I disconnect the A/P.L.Adamson
