Introduction - Diamond DA 40 Flight Manual

Mass & Balance

6.1 INTRODUCTION

In order to achieve the performance and flight characteristics described in this Airplane
Flight Manual and for safe flight operation, the airplane must be operated within the
permissible mass and balance envelope.
The pilot is responsible for adhering to the permissible values for loading and center of
gravity (CG). In this, he should note the movement of the CG due to fuel consumption.
The permissible CG range during flight is given in Chapter 2.
The procedure for determining the flight mass CG position at any point in time is described
in this Chapter. Over and above this there is a comprehensive list of the equipment
approved for this airplane (Equipment List), as also a list of that equipment installed when
the airplane was weighed (Equipment Inventory).
Before the airplane is delivered the empty mass and the corresponding CG position are
determined, and entered in Section 6.3 - MASS AND BALANCE REPORT.
Following equipment changes the new empty mass and the
corresponding CG position must be determined by calculation
or by weighing.
Following repairs or repainting the new empty mass and the
corresponding CG position must be determined by weighing.
Empty mass, empty mass CG position, and the empty mass
moment must be certified in the Mass and Balance Report
by an authorized person.
