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
Army models C -12R, C-12T3, and C-12F3
aircraft are in Weight and Balance 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. Figure 6-1, Sheets 1 through 3,
illustrates the general description of the aircraft
compartments in three configurations, i.e., passenger,
med-evac, and ferry fuel.
Section II. WEIGHT AND BALANCE
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:
Chart C - Basic Weight and Balance
Record, DD Form 365-3.
Form F - Weight and Balance Clearance
Form F, DD Form 365-4. (Transport).
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.
6-8. WEIGHT AND BALANCE CLEARANCE FORM
F, DD FORM 365-4.
Refer to TM 55-1500-342-23 for Form F, 365-4
instructions. Refer to Tables 6-1 through 6-3 for
weight and balance data.
