Reference Datum is an imaginary vertical plane from
which all horizontal distances a.re measured for balance
purposes.
Station is a location along the airplane fuselage giV'en in
terms of the distance from the reference datum.
Arm is the horizontal distance from the reference datum to
the center of gravity (C.G.) of an item.
Moment is the product of the weight of an item multiplied
by its arm. (Moment divided by the constant 1000 is used in
this handbook to simplify balance calculations by reduc-
ing the number of digits .)
Center of Gravity is the point at which an airplane, or
equipment, would balance if suspended. Its distance from
the reference datum is found by dividing the total moment
by the total weight of the airplane.
Center of Gravity Arm is the arm obtained by adding the
airplane's individual moments and dividing the sum by
the total weight.
Center of Gravity Limits are the extreme center of gravity
locations within which the airplane must be operated at a
given weight.
Standard Empty Weight is the weight of a. standard
airplane, including unusable fuel, full opera.ting fluids and
full engine oil.
Basic Empty Weight is the standard empty weight plus the
weight of optional equipment.
Useful Load is the difference between ramp weight and the
basic empty weight.
Ma.xi.mum Ramp Weight is the maximum weight approved
for ground maneuver . (It includes the weight of start, ta.xi
and runup fuel.) (

Takeoff Weight is the maximum weight ap-
proved for the start of the takeoff run.

INTRODUCTION
Section 2 includes operating limitations, instrument markings , and
ba.sic placards necessary for the safe operation of the airplane, its engine ,
standard systems and standard equipment. The limitations included in
this section and in Section 9 have b een approved by the Federal Av iation
Administration . Observance of these operating limitations is re quired by
Federal Aviation Regulations.
NOTE
Refer to Section 9 of this Pilot's Operating Handbook for
a.mended operating limitations , operating procedures ,
performance data and other necessary information for
airplanes equipped with specific options .
NOTE
The airspeeds listed in the Airspeed Limitations chart
(figure 2-1) and the Airspeed Indicator Markings cha.rt
(figure 2- 2) are b ased on Airspee d Calibration data shown
in Section 5 with the normal static source. If the alternate
static source is being used , ample margins should be
observed to allow for the airspeed calibration variations
between the normal and alternate static sources as shown
in Section 5.
Your Cessna is certificated under FAA Type Certificate No. 3A17 as
Cessna Model No . R172K .
