NORMAL
PROCEDURES
The electric fuel pump should
be
turned
OFF
after starting
or
during
warm-up to make sure that the engine driven pump
is
operating. Prior to
takeoff the electric pump should
be
turned ON again to prevent loss
of
power during takeoff should the engine driven pump fail. Check both oil
temperature and oil pressure. The temperature may be low for some time if
the engine
is
being run for the first time of the day. The engine
is
warm
enough for takeoff when the throttle can be opened without the engine
faltering.

BEFORE
TAKEOFF
All aspects of each particular takeoff should be considered prior to
executing the takeoff procedure.
Insure that the master switch
is
ON. Check and set all of the flight
instruments as required. Check the fuel selector to make sure it
is
on the
proper tank
(fullest). Turn
ON
the electric fuel pump
and
check the engine
gauges. The carburetor heat should
be
in
the
OFF
position.
All seat backs should be erect and the seat belts and shoulder harness
should be fastened.
Pull test the locking restraint feature
of
the shoulder
harness inertia reel. Fasten the seat belts snugly around the empty seats.
The mixture should be set, and the primer should be checked to insure
that it
is
locked.
NOTE
The mixture should be set FULL RICH, but a
minimum amount of leaning
is
permitted for
smooth engine operation when taking off
at
high elevation.
Exercise and set the flaps
and
trim tab. Insure proper flight control
movement and response. All doors should be properly secured and latched.
On air conditioned models, the air conditioner must be
OFF
to insure
normal takeoff performance.
