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.
The flight and operational characteristics of your airplane are normal
in all respects. There are no "unconventional" characteristics or opera-
tions that need to be mastered. All controls respond in the normal way
within the entire range of operation. All airspeeds mentioned in Sections
I and II are indicated airspeeds. Corresponding calibrated airspeed may
be obtained from the Airspeed Correction Table in Section V.
