I haven't flown any a/c with AP myself in reality, but as has been said the AP moves the yoke, so that the pilot can add input over the AP. Disabling joystick inputs alltogether should not be an option, except - perhaps - if you only disable a single axis. Assume that your AP is in ALT hold mode and you want to do turns. Using trim for the AP is possibly an intermediate solution, but I know that in JSBSim and in YASim you can define control sums, i.e., add different inputs together to make the input given to the FDM. If people have a problem with the AP modifying trim, we could as well give the AP its own input channel for each axis it should control. This input channel would neither be trim nor would it block user input on the joystick. OTOH if we're not that much after exact internal modelling, we might as well use the trim channel ;-) Cheers, Ralf ------------------------------------------------------------------------- Take Surveys.
