mation about your Cessna's eqUipment, operating procedures, and per-
formance; and suggestions for its servicing and care. We urge you to
read it from cover to cover, and to refer to it frequently.
Our
interest in your flying pleasure has not ceased with your purchase of
a Cessna. World-wide, the Cessna Dealer Organization backed by the
Cessna Service Department stands ready to serve you. The following
services are offered by most Cessna Dealers:
FACTORY TRAlNED PERSONNEL to provide you w.ith courteous
expert service.

OPERATING CHECK LIST
One of the first steps in obtaining the utmost performance, service,
and flying enjoyment from your Cessna is to familiarize yourself with your
airplane's eqUipment, systems, and controls. This can best be done by
reviewing
this equipment while sitting in the airplane. Those items whose
function and operation
are not obvious are covered in Section II.
Section I
lists, in Pilot's Check List form, the steps necessary to
operate your airplane efficiently and safely. It is not a check list in its
true form as it is considerably longer, but it does cover briefly all of the
points that you should know for a typical flight. All information in this
section is based on twin engine operation. For single engine operation
and procedures, reference should be made to Section III.
The flight and operational
characteristics of your airplane are normal
in all respects. There are no critical single-engine characteristics or
operations that need to be mastered and maintained at a high level of pro-
ficiency. All controls respond in the normal way within the entire range
of operation. All airspeeds mentioned in Sections I, II and III are indicated
airspeeds unless otherwise noted. Corresponding calibrated airspeeds
may be obtained from the Airspeed Correction Table in Section VI.
BEFORE ENTERING THE AIRPLANE.
(1) Make an exterior inspection in accordance with figure 1-1.

FUEL SYSTEM.
The maln fuel system is composed of two main fuel tanks (276 lbs.
usable each wing) in each outboard wing panel and one sump tank in the
lower portion of
each boom. Fuel flows from the sump tanks through a
by-pass in each auxiliary fuel pump (when it is not operating) to selector
valves located at the wing roots. Fuel is normally fed from the left wing
tanks and
front selector valve to the front engine, and from the right wing
tanks and
rear selector valve to the rear engine. It is pOSSible, however,
to feed either engine from either main fuel tank.
NOTE
The fuel selector valve handles should be turned to
"LEFT MAIN" for the front engine and "RIGHT MAIN"
for the rear engine durlng take-off, landing, and all
normal operations.
Depending upon the setting of the selector valves, fuel from the tanks
being used flows through the fuel
strainers to the engine-driven fuel pumps.
From here, the fuel is distributed to the engine cylinders via fuel control
units and fuel distributors. Vapor and excess fuel from the engine-driven
fuel pumps are returned to the main tanks and fuel sumps. The main fuel
tanks are vented at the wing tips and the auxiliary fuel tanks are vented
below the wing just forward of the inboard flaps.

AUXILIARY FUEL PUMP SWITCHES.
The auxiliary fuel pumps are electrically operated and are located in
the inboard wing panels near the leading edge. The pumps are controlled
by two split rocker-type switches located on the lower left switch and con-
trol panel. The switches are labeled "AUX PUMPS", "LEFT MAIN" and
"RIGHT MAIN." One
side of each switch is red in color and is labeled
"HI"; the other side is yellow in color and is labeled "LOW." The "LOW"
side operates the pumps at low speed, providing sufficient fuel for pri-
ming and starting. The "HI" side operates the pumps at high speed, sup-
plying sufficient fuel flow to maintain normal power in the event of engine-
driven fuel pump failure. In addition, the "HI" side should be used for
vapor elimination in flight, normal engine starts in very hot or cold
weather, and in-flight engine starts after running an auxiliary fuel tank
dry.
When the engine-driven fuel pump is functioning and the auxiliary fuel
pump is turned on "HI, .. a fuel/air ratio considerably richer than best
power is produced unless the mixture is leaned. With the engine stopped
and the master switch on, the cylinder intake ports can be flooded if the
"HI" side of the auxiliary fuel pump switch is aCcidentally turned on.
If it is desired to completely exhaust the contents of an auxiliary fuel
tank in flight, the auxiliary fuel pump will be needed to assist in restart-
ing the engine when fuel exhaustion occurs. Therefore, proper operation
of the auxiliary fuel pump should be verified prior to running the auxiliary
tank dry by turning the auxiliary fuel pump on momentarily (while using
from the main tank) and checking for a slight rise in fuel flow indication.
To ensure a prompt engine restart in flight after running an auxiliary
fuel tank dry, switch to the main tank containing fuel at the first indica-
tion of fuel pressure fluctuation and/or a power loss, and place the auxili-
ary fuel pump SWitch in the "HI" pOSition momentarily (3 to 5 seconds) with
the throttle at least 1/2 open. Excessive use of the "HI" position of the
auxiliary pump can cause flooding of the engine as indicated by a short (1
to 2 second) period of power followed by a loss of power. This can later
be detected by a fuel flow indication accompanied by a lack of power. If
flooding does occur, turn off the auxiliary fuel pump switch. Normal pro-
peller windmilling should start the engine in 1 to 2 seconds.
If the propeller should stop (possible at very low airspeeds) before
the tank containing fuel is selected, place the auxiliary fuel pump switch
In the "HI" pOSition and advance the throttle promptly until the fuel flow
