Current Position - (Throttle Curve)
Indicates which throttle curve is being displayed. Ordinarily there are 2 possible throttle
curves Pos.0 and Pos.1. However if the Twin Engine feature has been activated in Wing
TYPE, there will be 4 possible throttle curves available consisting of a Pos.0 and a Pos.1
for each of the 2 engines/throttle channels. They will be labeled RTH.0, RTH.1, LTH.0,
and LTH.1.
To view the other throttle curve, highlight and select Pos.0 or RTH.0 and select the
desired curve for viewing and editing.
Position - (Throttle Curve)
This element changes from 0 to 1 depending on the position of the switch used to select
between the 2 throttle curves.
Note: this indicator does not necessarily reflect the throttle curve that is currently
displayed, but rather just the switch position. To change which curve is actually
displayed, the Current Position parameter must be selected and changed as described
above.
Current Point Setting - (Throttle Curve)
This list shows the setting for each of the 7 adjustable points (Point-L, 1, 2, 3, 4, 5, H).
The value of each point determines where the point is positioned vertically on the graph,
which dictates the throttle servo position. The point values can be set from 0 to100 with
0 being full low stick at the bottom of the graph and 100 being full high stick at the top of
the graph. The overall travel from low to high is determined by the travel settings
described earlier in the TRVL ADJ. function.
A point value of INH can also be set for points 1, 2, 4, and 5. When set to INH the point
takes on a value represented by the intersection of the cursor and the Curve/Line between
the 2 adjacent points. For instance, if Point-1 is set to 16.0, Point-2 is set to INH and
Point-3 is set to 50.0, then Point-2, which is inhibited, takes on a value of 33.0, which is
midway between points 1 and 3.
The value for a point can be changed by highlighting and selecting the Point Name to the
left of the point value and then dialing-in the desired value.
Pressing the CLR button when a point value is highlighted resets the point to original
settings. The original settings are 0.0% for point-L, INH for points 1, 2, 4, and 5, 50%
for Point-3, and 100% for Point-H.
Cursor - (Throttle Curve)
The cursor shows the current throttle stick position. When the throttle stick is at full low,
the cursor is to the extreme left over Point-L, when it is ½ throttle it is in the center over
Point-3 and when it is at full high throttle the cursor is at the extreme right of the graph
over Point-H.
The cursor moves across the 7 points as the throttle is moved from low to high. Where
the cursor intersects the Curve/Line over a given point defines the amount of servo
deflection, which is equal to the value assigned to the point. For example, if Point-3 is
set to 30% then the servo will deflect 30% from full low when the throttle is advanced so
the cursor is over that point.
