L E ⁄ F L P M is highlighted. Press the Selectorto
access the Elevator-to-Flap mix menu. Note that two
elevator-to-flap mix values are available, Pos0 and
Pos1, and that the elevator-to-flap values can be
independently adjusted up and down. Also the offset
(the stick position where the mixing changes from up to
down) can be adjusted. This offset allows the
programming of snap-flaps, a common sailplane function
that
gives greater full up elevator pitch
authority for tighter turns. With snap-flaps, no flap
mixing occurs during small to medium up elevator
inputs, but at about 80% up elevator, the flaps are
mixed to give down flaps, causing greater up pitch
authority.
Rotate the Selector to highlight CRU (cruise mode) at
the bottom of the screen and depress the Selector to
select Pos1. If you choose to program snap-flaps,
rotate the Selector until the Offset Pos1 is highlighted
and depress the Selector to access this value. A 0 value
locates the offset position when the elevator is
centered. The adjustment range is -200 to +200.
Negative values move the offset in the up elevator
direction. Set a value of œ 100 to start, as this will locate
the offset at 80% up elevator. Press the Selector to store
this
offset value. Rotate the Selector to highlight Pos1 U
P
and depress the Selector to access the position 1 up
elevator mixing. With the 3-position switch in the middle
(cruise) position, give a full up elevator command and
hold while adjusting the Pos1 up value until the desired
down flap position is achieved. Press the LIST button to
return to the Function Mode screen.
