B. WEIGHT AND BALANCE MANUAL
WEIGHT AND BALANCE MANUAL INTRODUCTION
The Weight and Balance Manual is the reference as far as weight, balance and loading are concerned. It is the document released by the manufacturer and given to the operator with the aircraft that contains all necessary information to determine loading instructions or to produce the Load and Trim Sheet.
The purpose of this chapter is to present the information included in the WBM. This document is divided into three sections : . 0.00 Arrangement of introduction pages, which contains all the pages describing the manual (Table of contents, List of figures …), . 1. Weight and balance control, which describes generic weight and balance data for the concerned aircraft, . 2. Aircraft weighing reports, which gives the results of the aircraft weighing (Operating Empty Weight and corresponding CG position).

1. SECTION 1 : WEIGHT AND BALANCE CONTROL
This section is divided into ten parts.
1.1. 1.00: GENERAL
This part of the WBM presents first generic information such as a list of abbreviations, different weight definitions and conversion factors.
Then it provides drawings and a description of the general characteristics of the aircraft.
B. WEIGHT AND BALANCE MANUAL
. The effect of moving components (1.00.10) is used to determine the influence of the landing gear retraction and/or flaps/slats extension on the aircraft CG position (see B3.1 Principle of Error calculation).
1.2. 1.10: LIMITATIONS
This chapter deals with the different weight and balance limitations applied to the aircraft.
The first ones are certified limits, i.e. the maximum weights (1.10.01) and the certified CG limits (charts and diagrams 1.10.02). These certified CG limits are the starting point for the determination of the operational flight envelope.
