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 RC-12K aircraft are in Weight and Balance
Class 1. Additional directives governing weight and
balance of Class 1 aircraft forms and records are
contained in AR 95-3, TM 55-1500-342-23 and DA PAM
738-751.

AIRCRAFT
COMPARTMENTS
AND
STATIONS.
The Aircraft is separated into two compartments
associated with loading. These compartments are the
cockpit and the cabin. Figure 6-1 shows the general
description of aircraft compartments. Figure 6-2 shows
the landing gear dimensional data.
Section II. Weight and Balance
6-4.
PURPOSE.
The data to be inserted on weight and balance charts
and forms are applicable only to the individual aircraft,
the serial number of which appears on the title page of
the booklet entitled WEIGHT AND BALANCE DATA
supplied by the aircraft manufacturer 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 principles 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:
1.
Chart C - Basic Weight and Balance Record,
DD Form 365-3.
2.
Form F - Weight and Balance Clearance Form
F, DD Form 365-4 (Tactical).
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.
6-7.
CHART C - BASIC WEIGHT AND BALANCE
RECORD, DD FORM 365-3.
Chart C is a continuous history of the basic weight and
moment resulting from structural and equipment
changes made in service. At all times, the last weight
and moment/100 entry is considered the current weight
and balance status of the basic aircraft.
NOTE
Weight
and
balance
data
on
Extended Band Kits is included with
kit
drawings
and
will
be
accomplished by field installation
personnel.
6-8.
WEIGHT AND BALANCE CLEARANCE FORM
F, DD FORM 365-4 (TACTICAL).
Refer to TM 55-1500-342-23 for Form F, 365-4
instructions. Refer to Table 6-1 through 6-4 for weight
