AILRUD M – AILERON-TO-RUDDER MIXING
A30
The XP9303 also features a built-in mixer for Aileron-
to-Rudder. The mixer causes the Rudder to deflect when
the Ailerons are moved resulting in coordinated turns.
This is a useful function for high-wing aircraft with flat-
bottomed airfoils because the Ailerons are typically not
very effective, and Rudder input combined with Aileron
input dramatically improves the turn and bank authority
for these aircraft. The Rudder normally moves in the
same direction as the Ailerons, however, the Rudder can
be made to move in either direction by using positive or
negative values.
If the aircraft requires Aileron-to-Rudder mixing, perform
the steps below.
1. Highlight and select AILRUD M in the FUNC.LIST
to obtain the Aileron-to-Rudder mix display.
2. There are 2 sets of mixing values available – Pos0 and
Pos1. If the Pos0 values are left at 0% then the mixer
may be turned on and off – Pos0 would be off and
Pos1 would be on (this can be reversed by leaving
the Pos1 values at zero and putting values into Pos0).
Highlight and select L next to Pos1 and set the value
to give the desired amount of Left Rudder. A negative
value will reverse the direction.
3. Highlight and select R next to Pos1 and set the value
to give the desired amount of Right Rudder. A negative
value will reverse the direction.
4. Scroll down to the bottom line of the display to select
the Flight Mode and/or switch(es) that is to be used to
turn the mixer on and off. The example below shows
Flight Mode 2 set to Pos1, turning on the Aileron-to-
Rudder mix. The throttle may also be used to turn the
mixer on and off by highlighting and selecting THRO
STK and setting the percentage of throttle to the point
where the mixer is switched on/off.
Note: The Pos0 values can also be set to something
other than zero causing a different amount of Rudder
deflection to occur when there is Aileron input. One
or more switches can then be selected to switch
between the two sets of values. With this setup there
will always be some mixing, as indicated by either
Pos0 or Pos1, and the mixing cannot be turned off.
Note: Pos1 always has priority over Pos0. In other
words, if multiple switches are selected to turn the
mixer on and off and one of the switches is in its
Pos1 position, then all other switches are ignored
and the Pos1 values are in effect.
