Flight Level Change Mode (FLC)
1) Select the desired altitude by turning the
ALT
Knob to set the altitude in the Altitude
Select Box. This altitude must be selected first
because Flight Level Change mode will only fly
toward a selected altitude.
2) Press the
FLC
Key. The flight director is
activated (if not already active) and ‘FLC’ is
now displayed in green in the Active Mode
field and the Airspeed Bug will appear on the
Airspeed Indicator. Pitch commands are given
to manually maintain airspeed. Press the
AP
Key to engage the autopilot for maintaining
the current airspeed.
Altitude Hold mode is automatically armed with
‘ALT’ displayed white in the Armed Mode field
to the right of the ‘FLC’ annunciation.
3) The Airspeed Bug can be adjusted in 1 knot
increments by pressing the
NOSE UP/NOSE DN
Keys to set the desired airspeed. The airspeed
setting will be displayed in the Selected

4) Airspeed may also be changed by pressing and
holding the
CWS
button to manually establish
the desired airspeed using the control wheel.
When the
CWS
button is released, the current
airspeed will be maintained.
5) Adjust engine power to allow the autopilot
to fly the aircraft at a pitch attitude which
corresponds to the selected airspeed and the
desired flight profile (descent or climb).
6) With Altitude Hold mode armed, as the selected
altitude is reached, ‘ALT’ will flash in green
for 10 seconds in the Acitve Mode field, after
which the annunciation stops flashing. This
signals the altitude capture is complete and
the selected altitude will be maintained at the
selected airspeed. If only the flight director
is engaged, pitch commands are given to
manually maintain the selected altitude.
