ELEV – ELEVATOR COMPENSATION (Flap System)
A25
The ELEV values represent the Elevator deflection that
will occur when the Flaps are deployed to their various
positions. Some trial and error will probably be required
to arrive at the right values, but once set, the aircraft will
assume the proper pitch attitude for all flap positions.
1. Make sure the NORM value next to ELEV is set to
0% as there should be no Elevator deflection with
the flaps in their fully retracted (up) position. If it
is not 0%, scroll to NORM next to ELEV, select it,
and then set the value to 0%.
2. Scroll to the Mid parameter beside ELEV and select it.
Set the value either U (up) or D (down) to introduce up
or down Elevator trim for the Mid position of the flaps.
If not sure about which direction, aircraft typically pitch
Up when flaps are deployed, requiring some Down
Elevator input to compensate. Use a small percentage
like 3–5% at first and, after test flying, adjust the value
a little at a time until the aircraft maintains the correct
pitch attitude (typically slightly nose down) when the
flaps are deployed to the Mid position.
3. Scroll to the Land parameter beside ELEV on the
display and press the Selector to select it. Set the
value either U (up) or D (down) to introduce a small
amount (5–10%) of up or down Elevator for the Land
position of the flaps, in the same fashion as setting up
the Mid position above.
