Trim Step
S-10
The Trim Step function provides for adjusting the
sensitivity of the trim levers. It is useful during and after
initial trimming of the aircraft, in order to trim the aircraft
quickly at first and then to make very precise adjustments
to aircraft trim. When adjusting the digital trims (AILE,
ELEV, RUDD, FPRN, FLAP), the total trim travel does not
change—only the number of increments (beeps) changes,
which makes for finer or coarser trim movements. The
digital trims may have a setting of 0–10 with 10 being the
coarsest adjustment. When the value is set to 10, there are
only 10 trim increments from center to each end. When
set to 5, there are 20 trim increments from center to each
end. When set to 4 there are 25 increments. When set to
3 there are 34 increments and when set to 1 there are 100
trim increments. When set to 0 the trim levers cease to
function and can no longer be used to change the trim of
the aircraft.
When adjusting the analog spoiler trim, however, the
total trim travel is actually reduced when set to less than
100%.
Use a fairly coarse setting such as 4–6 when test flying an
aircraft in order to be able to trim the aircraft quickly, and then
use a finer setting such as 3–1 for final precision trimming.
