WEIGHT/BALANCE AND LOADING
Section I. GENERAL
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.
Army model RC-12P and RC-12Q mission equipment
aircraft are in Weight and Balance Class 1. When
operating in a passenger/cargo configuration, the aircraft
weight and balance classification becomes a Class 2.
Additional directives governing weight and balance
classifications 1 and 2 aircraft forms and records are
contained in AR 95-1, TM 55-1500-342-23, and DA PAM
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.
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.
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 F - Weight and Balance Clearance, DD
Form 365-4 (Tactical).
The aircraft manufacturer inserts all aircraft identifying
data on the tide 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.
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.
WEIGHT AND BALANCE CLEARANCE, DD
FORM 365-4 (TACTICAL).
Refer to TM 55-1500-342-23 for DD Form 365-4
instructions. Refer to table 6-1 through 6-5 for weight
and balance data.
