BRAKE FLAP-ELEVATOR MIXING
—5-S
This
function
is
used
to
correct
the
trim
change
that occurs when the brake flaps are moved by
applying a small amount of elevator. For example,
if the fuselage pitches up when the brake flaps are
actuated, the elevator is commanded down simul-
taneously.
The mixing rates for up and down brake flap
commands can be set independently. Mixing can
be turned on and off during flight by setting a
switch, and you may also define a volume control
to change the mixing rate in flight. Brake flap
mixing remains on all the time unless an ON/OFF
switch is defined.
