BEFORE TAKEOFF
Both fuel tank selector valves should always be placed in the ON position
prior to engine start and takeoff. It is permissible to turn one side OFF as
necessary to balance the fuel load if an out of balance condition exists. This
should be performed either on the ground or during cruise at a safe altitude.
Prior to the rst ight of the day, perform an operational check of the engine
inlet / inertial separator system. Cycle the ENG INLET switch and check that
the position is annunciated appropriately on the PFD.
A takeoff index range is provided on the elevator trim tab position indicator.
As the aircraft is loaded to an aft or forward C.G. condition, the elevator trim
setting should be adjusted to compensate for the condition for which the
aircraft is loaded. The pointer on the rudder trim indicator normally moves
slightly during taxi and when the rudder pedals are being moved. To achieve
a steady and accurate indication for setting the rudder trim for takeoff, set the
rudder trim with the aircraft stopped and the nose wheel centered, parking
brake set and feet off of the rudder pedals.
Refer to the Systems Checks / Procedures following the Checklist Procedures
portion of this section for procedures to follow when checking the overspeed
governor, aileron trim, elevator trim and audio panel equipment.
The automatic trim compensation system is disabled on the ground through
an airspeed switch to prevent accidental placing of the aircraft in an out-
of-trim condition before takeoff, i.e. the pilot sets the pitch trim for takeoff,
then selects the aps to takeoff position (20°), and the auto trim system runs
the pitch trim nose down. The airspeed switch activates the automatic trim
system at approximately 35 knots. In high wind conditions, the airspeed
switch may allow the auto-trim system to operate on the ground. Before
taxiing onto the runway for takeoff, double check the elevator trim indication to
ensure it is positioned properly for takeoff.
Prior to takeoff, move the fuel condition lever forward to the HIGH IDLE
position. Leave the fuel condition lever in this position until after landing. The
HIGH IDLE gas generator speeds allow for faster engine acceleration when
adding power from an idle condition.
WARNING: Do not exceed a fuel imbalance of greater than 250 pounds
in ight.
