Butterfly Mix (Landing Flaps)
S-26
The Butterfly Mix is the landing program that mixes the
flaps, flaperons (ailerons as flaps) and elevator to the
spoiler (throttle) stick. Two values are available, Pos0
and Pos1, and each can be assigned to several different
switches or flight modes. An offset is provided to allow
the user’s preference for the neutral position (normally
stick up).
To access the Butterfly menu, in FUNC.LIST rotate
the Selector until
Butterfly is highlighted. Press the
Selector to access the Butterfly menu.
Note: The default setting for offset is at +170%.
With this setting, the flap’s neutral position (trailing
edge level) occurs when the spoiler stick is in the full up
position. If you choose to locate the neutral position in
the down position, the value would be –170%. Rotate the
Selector to highlight SW select and press the Selector
to access the available switches. The default setting is
the BTF or butterfly switch. To access the various values,
rotate the Selector to highlight them then depress the
Selector to access the value. Move the spoiler stick to
the full down position and adjust the value by rotating
the Selector until the desired position is achieved. Press
the Selector to store the value. You may wish to adjust
the
SPOIELEV, however, there is a curve mix in P-mix
1 that will allow several points on a curve to be adjusted
for flap-to-elevator mixing that we will be covering in
programmable mix 1. Press the LIST button to return to
the Function Mode screen.
