TRIM STEP
A16
The Trim Step function provides for adjusting the
sensitivity of the XP9303 trim levers and switches. 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. 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 digital trims (AILE, ELEV, RUDD,
FLAP, AUXT), the total trim travel does not change—only
the number of increments (beeps) changes, which makes
for finer or coarser trim movements. When adjusting
the analog throttle 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.
1. Highlight and select TRIM STEP in the Devic. SEL
display of the SYSTEM Menu to acquire the TRIM
STEP display.
2. Highlight and select the trim that is to be changed
and use the Selector to set a value of 1–10
(1 = finest, 10 = coarsest).
3. Repeat for other trims as desired.
This concludes the SYSTEM Menu portion of the ACRO
mode. Continue with FUNC.LIST below to complete the
aircraft setup.
