AUTO LAND (Flap System)
ELEV – ELEVATOR COMPENSATION (Flap System)

1. If using Auto Land, scroll to
INH
under
AUTO LAND
and select it with the
Selector
.
INH
will change to
ACT
when selected and toggles between
ACT
and
INH
each time the
Selector
is pressed.
The Auto Land feature, if implemented, automatically
retracts the Flaps and Elevator compensation when the
throttle is raised above a specified throttle position. This
can be useful during a missed landing approach when a
go-around is required. The Flap System allows the Flaps
to be deployed using the Flap Switch, Flight Mode switch
or a combination of both.
2. Scroll down to
THRO
and press the
Selector
to
show the throttle percentage. Rotate the selector
until the throttle percentage (0–100%) is equal to
where the Auto Land feature is to retract the Flaps
and Elevator compensation.
You should set the throttle position very high at first
(between 90–99%) to give the aircraft a chance to regain
some speed before the Flaps actually retract. As the Flaps
retract, lift will decrease and the stall speed of the aircraft
will increase and may cause a crash if the airspeed is
too low. When there is a missed approach, advance the
throttle slowly up to about 90% and wait until the aircraft
picks up some speed before advancing the throttle to full,
causing the Flaps to retract.
Highlight and select
FLAP SYS.
in the
FUNC.LIST
to
obtain the Flap System display if the aircraft has flaps or
Flaperons that are also going to be used as flaps.
The
ELEV
values represent the Elevator deflection that
occurs when the Flaps are deployed to their various
positions. Some trial and error will probably be required
to arrive at the right values, but once set, the aircraft will
assume the proper pitch attitude for all flap positions.
1. Make sure the
NORM
value next to
ELEV
is set to
0% as there should be no Elevator deflection with
the flaps in their fully retracted (up) position. If it
is not 0%, scroll to
NORM
next to
ELEV
, select it,
and then set the value to 0%.
2. Scroll to the
Mid
parameter beside
ELEV
and select it.
Set the value either
U
(up) or
D
(down) to introduce up
or down Elevator trim for the Mid position of the flaps.
If not sure about which direction, aircraft typically pitch
up when flaps are deployed, requiring some Down
Elevator input to compensate. Use a small percentage
like 3–5% at first and, after test flying, adjust the value
a little at a time until the aircraft maintains the correct
pitch attitude (typically slightly nose down) when the
flaps are deployed to the
Mid
position.
3. Scroll to the
Land
parameter beside
ELEV
on the
display and press the
Selector
to select it. Set the
value either
U
(up) or
D
(down) to introduce a small
amount (5–10%) of up or down Elevator for the Land
position of the flaps, in the same fashion as setting up
the
Mid
position above.
