Throttle Curve
Three different profiles for the carburettor response
can be adjusted and called up in flight by external
switches; the function of the throttle pre-select is
included in this changeover.
The curves are determined in each case by three
points:
• The low collective pitch / throttle stick position,
called "TL..." (T
hrottle Low),
• The middle collective pitch / throttle stick
position, called "TM..." (Throttle Middle),
• The high collective pitch / throttle stick position,
called "TH…" (Throttle High).
The three sets of adjustment are successively called
using the CH SEL button.
Selection of which of the three possible curves are to
be adjusted is by operation of the external switches
connect to the transmitter board connections 4 and
5; the display announcement changes accordingly:
Switch 3 = OFF, ATR inactive
Both switches in OFF position “T…1”
Switch 4 = ON, Switch 5 = OFF “T…0”
Switch 4 = ON or OFF, Switch 5 = ON “T…2”
Switch 3 = ON, ATR activated
Switch 4 and 5 = ON or OFF
The appropriate notice flashes as warning that the
autorotation changeover is activated and the
indicated value is not effective; instead the throttle
servo takes the position programmed in the setting
for autorotation (ATR).
Setting
After selection of the point required using the
CH SEL button and operation of the appropriate
external switches, the value displayed can be set
using the INC and/or DEC buttons over a range of
0... ±125 steps; pressing the CLEAR button resets
the value to the standard setting.
