MODEL 152 WEIGHT & BALANCE
EQUIPMENT LIST
1 July 1978 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.
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.
It is the responsibility of the pilot to ensure that the airplane is loaded properly.
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.
