my stec 55x (on my cessna) has auto-trim, which
means the auto-pilot senses the torque required to
maintain the desired flight condition and adjusts
the trim to keep that torque within some pre-specified
limit.
However, there is a pilot controlled trim
switch. If the pilot makes a trim change directly, the a/p
disengages. The reason for this is that
if it didn't, you could dial in lots of trim but you wouldn't
feel it because the a/p would be counteracting it,
until it couldn't any more at which time it will
disengage and hand you the airplane way out of
trim, resulting in an "excursion"
So I'm wondering if people put this disconnect
feature in their trim wiring
Colyn,
Please explain this?
Thanks
