CHAPTER 1
INTRODUCTION
1-1. Purpose. The purpose of this manual is to provide
information necessary for the control of weight and
balance of Army aircraft. Much of the information
contained herein is general in nature since it is
applicable to all aircraft. Refer to the appropriate -10
operator's and -23 maintenance manuals when specific
weight and balance data is required for a particular
aircraft.
1-2. Scope. Material presented in this manual applies
to all activities that operate and/or maintain Department
of the Army aircraft. Sufficient explanation of principles,
definitions, and procedural data are given to provide
weight and balance personnel with a general information
manual pertinent to their particular function. Also
included is a complete description of related equipment
and instructions for its use and operation.
1-3. Reasons For Weight And Balance Control.
Flight characteristics of aircraft are directly dependent
upon conditions of weight and balance. Gross weight
and
center of gravity (cg) have a bearing on performance,
stability, and control of the aircraft For example, cargo
placed too far aft in an already critically loaded aircraft
will move the center of gravity out of the permissible
balance limits. This could easily cause the pilot to lose
control of the aircraft. Hazardous flight conditions and
accidents resulting from these conditions can be
prevented by adherence to the principles of weight and
balance set forth in this manual.
1-4. Responsibilities. Basic weight and balance data
is delivered with the aircraft. Once aircraft are
delivered, however, it becomes the responsibility of
maintenance and operating units to maintain accurate
weight and balance data. Maintenance activities are
required to weigh specific aircraft periodically in
accordance with the provisions of AR 95-3 to insure that
basic weight and balance data is correct. It is the pilot's
responsibility to insure that the weight and balance
conditions of the aircraft are within safe limits, in
accordance with the provisions of AR 95-1.
