6.3.23 WEIGHING
(1)
GENERAL
This section describes the methods for determining the empty weight of the aircraft
and the position of its center of gravity relative to the datum.
Weight and balance limits are placed on aircraft for two reasons:

First, the structure was designed to carry a certain weight;

Second, the operating weight of the aircraft and the position of the center of
gravity affect performance, stability, and control characteristics, particularly in
stall and spin recovery.
The aircraft will only attain the performance and exhibit the handling characteristics
used for certification if it is flown when the weight and the center of gravity are within
the approved range.
Prior to leaving the factory, the aircraft was weighed and the C.G. location was
computed. You will find this information in paragraph 6.4 of the Pilot’s Operating
Handbook and Aircraft Flight Manual. If it should become necessary to re-weigh the
aircraft, follow the procedures given in this section.

PREPARATION
(a) Clean the aircraft to remove excess dirt and grease.
(b) Remove the fuel from the aircraft. This may be accomplished by opening the
fuel drains until all remaining fuel is drained.
(c) Check that the oil is full.
(d) Position the pilot’s seat in the mid position.
(e) Zero the scales or record the tare, as appropriate.
(3)
WEIGHING THE AIRCRAFT
(a) Place the aircraft on calibrated scales. The range of the scales should be
1000 lb. for each main wheel and 250 lb. for the tail wheel.
(b) Level the aircraft (Refer to Section 6.3.18).
(c) Record the weight of the main wheels and the tail wheel in Table 6.3.23.1 or
Table 6.3.23.2 depending upon the type of landing gear installed on the
aircraft.
