Flap→aileron mixing is used to
change the camber (the angle of the
ailerons and flaps) over the entire wing,
which produces less drag than just
dropping the flaps by themselves. When
you have Elevator→Flap mixing activated
along with Flap→Aileron mixing, the
entire trailing edge droops or reflexes with
elevator stick motion.
You can program an offset of the flaps
as described in step 3 below, but we
suggest leaving this at zero initially.
Switch "D" is programmed to turn this
function on and off, but you can have the
function always on if you like by selecting
the NULL direction.
Setting up Flap→Aileron mixing
1. Turn the FLP>AI function ON or OFF by pressing the
(+) key ("ON" or "OFF" displayed depending on switch D's
position). Turn off (INH) the function with the (-) key.

2. Aileron travel rate setting
Adjust the amount of aileron travel
compared to flap motion with the
(+)/(-) keys.
• If you're unhappy with what you've
set, you may return to the default
value by pressing the (+) and (-)
keys simultaneously.
3. Flap neutral position offset
Turn the CH6 knob in the desired
offset direction. Memorize the
amount of offset by pressing the
(+)/(-) keys simultaneously.
(Suggest leaving 0% initially)
4. Activation Switch Direction/Disabling
Select the desired direction for Switch D to turn the function on and off
with the (+)/(-) keys.
"UP" = Upper position turns on FLP-AI mixing
"DOWN" = Lower position turns on FLP-AI mixing
"NULL" = FLP-AI mixing is always on; switch disabled.
