CHAPTER 6
WEIGHT/BALANCE AND LOADING
Section I. GENERAL
6-1. EXTENT OF COVERAGE.
Sufficient data has been provided so that,
knowing the basic weight and moment of the aircraft,
any combination of weight and balance can be
computed.
6-2. CLASS.
Army Model C-12 is in class 2. Additional
directives governing weight and balance of class 2
aircraft forms and records are contained in AR 95-1,
TM 55-1500-342-23 and DA PAM 738-751.
6-3. AIRCRAFT COMPARTMENTS AND STATIONS.
The aircraft is separated into two compartments
associated with loading. These compartments are the
cockpit and the cabin. Sheet 1 from Figure 6-1
illustrates
the
general
description
of
aircraft
compartments of C D T1 and Sheet 2 illustrates T2 .
Section II. WEIGHT AND BALANCE
6-4. PURPOSE.
The data to be inserted on weight and balance
charts and forms is applicable only to the individual
aircraft whose serial number appears on the title
page of the booklet, supplied by the aircraft
manufacturer, entitled WEIGHT AND BALANCE
DATA and on the various forms and charts which
remain with the aircraft. The charts and forms
referred to in this chapter may differ in nomenclature
and arrangement from time to time but the principle
on which they are based will not change.
6-5. CHARTS AND FORMS.
The standard system of weight and balance
control requires the use of several different charts
and forms. Within this chapter, the following are
used:
a. Chart C – Basic Weight and Balance
Record, DD Form 365-3.
b. Form F – Weight and Balance Clearance
Form F, DD Form 365-4 (Transport).
6-6. RESPONSIBILITY.
The aircraft manufacturer inserts all aircraft
identifying data on the title page of the booklet
entitled, "Weight And Balance Data," and on the
various charts and forms. All charts, including one
sample Weight and Balance Clearance Form F, if
applicable, are completed at time of delivery. This
record is the basic weight and balance data of the
aircraft at delivery. All subsequent changes in
weight and balance are compiled by the weight and
balance technician.
