GRAUPNER mz-24 PRO - Aile Diff - AILE Differentiation (Glider)

Aile diff - Glider
Aileron Travel, Differentiation and Differentiation Reduction Settings
This submenu option is not available for models using
the 1AILE and 1AILE1FLAP settings.
An aileron deflected downward generates greater
aerodynamic resistance than one deflected upward.
The asymmetrical resistance generates torque around
the vertical axis which causes a turning out of the in-
tended flight direction. This is a naturally occurring
phenomenon for all winged models, however the
effect comparatively is stronger on the longer glider
wings and less on motorized airplanes whose lever
arms are typically much shorter. This undesirable
side-effect is called “adverse yaw” and must be com-
pensated for by a simultaneous, counteracting rudder
deflection.
The rudder deflection also generates additional resis-
tance and further impairs flight. If the rudder deflec-
tion is differentiated so that the downward deflection
of the aileron is less than the upward deflection, the
adverse yaw can be reduced or eliminated without
having to manually compensate the rudder each time
on the aileron control.

However, when the ailerons are raised as part of a
butterfly configuration, the adjusted aileron differenti-
ation has a disadvantageous effect, since the aileron
effect is strongly impaired. Another excursion of the
one aileron is almost impossible, though depending
on the position and degree of differentiation, often it
does not have the neutral position. The automatic dif-
ferentiation reduction option reduces the degree of ai-
leron differentiation continuously and in an adjustable
manner when the brake system is extended or even
set them up, depending on the setting.
To adjust these settings, from the main display press

Phase-Dependent Settings
This submenu allows for different phase-specific val-
ues to be programmed. Phase names are displayed
in green in the upper left side of the screen next to
the BACK button. Standard default naming for the
phases are usually displayed as NORMAL/PHASE
1. (Additional phases will be named numerically, e.g.
Phase 2, Phase 3, etc.) To define multiple phases,
refer to the FUNCTION submenu Phase section (page
120). Each new phase will need to be assigned to a
different switch. To change the phases, activate the
corresponding switch(es).
