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 is described in this chapter. Additionally a comprehensive list of the equipment approved for this airplane exists (Equipment List). The set of items marked as 'installed' constitutes the 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.
NOTE
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 authorized personnel.
NOTE
Refer to Section 1.6 UNITS OF MEASUREMENT for conversion of SI units to US units and vice versa.
6.2 DATUM PLANE
The Datum Plane (DP) is a plane which is normal to the airplane’s longitudinal axis and in front of the airplane as seen from the direction of flight. The airplane’s longitudinal axis is parallel with the floor of the nose baggage compartment. When the floor of the nose baggage compartment is aligned horizontally, the Datum Plane is vertical. The Datum Plane is located 2.196 meters (86.46 in) forward of the most forward point of the root rib on the stub wing.
6.3 MASS AND BALANCE REPORT
The empty mass and the corresponding CG position established before delivery are the first entries in the Mass and Balance Report. Every change in permanently installed equipment, and every repair to the airplane which affects the empty mass or the empty mass CG must be recorded in the Mass and Balance Report.
For the calculation of flight mass and corresponding CG position (or moment), the current empty mass and the corresponding CG position (or moment) in accordance with the Mass and Balance Report must always be used.
Condition of the airplane for establishing the empty mass:
-Equipment as per Equipment Inventory (see Section 6.5)
-Including the following operating fluids:
brake fluid
hydraulic fluid (for the retractable gear)
engine oil (2 x 6.0 liters = 2 x 6.3 qts)
