CESSNA AIRCRAFT COMPANY FOR TRAINING USE ONLY
MODEL 152 6-3
INTRODUCTION
This section describes the procedure for establishing the basic empty weight and moment of the
airplane. Sample forms are provided for reference. Procedures for calculating the weight and moment
for various operations are also provided. A comprehensive list of all Cessna equipment available for this
airplane is included at the back of this section.
It should be noted that specific information regarding the weight, arm, moment and installed equipment
list for this airplane can only be found in the appropriate weight and balance records carried in the
airplane.
AIRPLANE WEIGHING PROCEDURES
1. Preparation
a. Inflate tires to recommended operating pressures.
b. Remove the fuel tank sump quick-drain fittings and fuel line drain plug to drain all fuel.
c. Remove oil sump drain plug to drain all oil.
d. Move sliding seats to the most forward position.
e. Raise flaps to the fully retracted position.
f. Place all control surfaces in neutral position.
2. Leveling
a. Place scales under each wheel (500# minimum capacity for scales).
b. Deflate nose tire and/or lower or raise the nose strut to center bubble on level (see figure 6-
1).
3. Weighing
a. With the airplane level and brakes released, record the weight shown on each scale. Deduct
the tare, if any, from each reading.
4. Measuring
a. Obtain measurement A by measuring horizontally (along the airplane center line) from a line
stretched between the main wheel centers to a plumb bob dropped from the firewall.
b. Obtain measurement B by measuring horizontally and parallel to the airplane center line,
from center of nose wheel axle, left side, to a plumb bob dropped from the line between the
main wheel centers. Repeat on right side and average the measurements.
5. Using weights from item 3 and measurements from item 4, the airplane weight and C.G. can be
determined.
6. Basic Empty Weight may be determined by completing figure 6-1.
