Programmable throttle curves allow the throttle response (stick
position vs. throttle output) to be manipulated. This is useful to
optimize the throttle response for various maneuvers like torque
rolls. Programmable throttle curves can be adjusted with the
THRO CURV function. Two programmable throttle curves are
available.
If the Twin E. function has been activated in Wing Type (page
A-27 for twin-engine aircraft, independent throttle curves are
available for each engine to help eliminate discrepancies in rpm
between the two engines at all throttle positions.
18: Throttle Curves
1. Highlight and select THRO CURV in the FUNC.LIST. and
press YES or NO to access the throttle curve function. Two
different throttle curves can be programmed referenced to
as Pos0 and Pos1.
2. If there is a need to have 2 throttle curves, use the Selector
to highlight SW SELECT and a list of available Flight
Modes and switches appears. Select the Flight Mode(s)
(FM0, FM1, or FM2), switches and/or switch position
(SPS) that is desired to be used to select between the 2
curves. The switch will be used to select between the Pos0
curve and the Pos1 curve. Highlight and select Pos0 to
toggle between the Pos0 and Pos1, in order to display and
adjust the 2 curves.
Note
: If Twin E. has been activated for a twin engine
aircraft, there will be a Pos0 and Pos1 for both the right
and left engines, providing a total of 4 possible throttle
curves. However, instead of being named Pos0 & Pos1,
they are named RTH.0, RTH.1, LTH.0, and LTH.1. They
represent Right Throttle Pos0 & Pos1 and Left Throttle
Pos0 & Pos1 respectively.
3. Highlight EXP and select it to turn exponential ON if
desired. This will result in a smoothed throttle curve.
4. Using the roller, highlight the desired point (L, 1, or H) and
press the roller to access the output value. Rotate the roller
to change the output value. Repeat for all desired points.
Note the graphic display will change to represent the new
point position.
5. To adjust access Pos1 throttle curve (only available when
SW is assigned to a switch) highlight Pos0 and rotate the
roller to access Pos1 and repeat the step above to adjust
Pos1 throttle curve.
6. To adjust the throttle trim authority, highlight the TRIM
using the roller and rotate to select a trim authority value of
0 100%. Note the graphic display will change to represent
the new trim authority.
7. To store a new point move the throttle stick until store
appears on the lower left side of the screen. When the
desired position is achieved press the store button and the
point will be stored onscreen. Up to eight points can be
stored.
9. THRO STK allows the throttle stick to be used to switch
from Pos0 throttle curve to Pos1 throttle curve. To program
a throttle curve Pos change with the throttle stick highlight
the THRO STK and adjust the values using the roller to
program the point at which the throttle curve is selected
between Pos0 and Pos1.
