6.4 FLIGHT MASS AND CENTER OF GRAVITY
The following information enables you to operate your DA 42 within the permissible mass and balance limits. For the calculation of the flight mass and the corresponding CG position the following tables and diagrams are required:
6.4.1 MOMENT ARMS
6.4.2 LOADING DIAGRAM
6.4.3 CALCULATION OF LOADING CONDITION
6.4.4 PERMISSIBLE CENTER OF GRAVITY RANGE
6.4.5 PERMISSIBLE MOMENT RANGE
The diagrams should be used as follows:
1.
Take the empty mass and the empty mass moment of your airplane from the Mass and Balance Report, and enter the figures in the appropriate boxes under the column marked ‘Your DA 42' in Table 6.4.3 - 'CALCULATION OF LOADING CONDITION'.

2.
Read the fuel quantity indicators to determine the fuel quantity in the main fuel tanks.

3.
Determine the fuel quantity in the auxiliary fuel tanks (if installed).


To verify an empty auxiliary fuel tank, set the ELECT. MASTER switch and the FUEL TRANSFER switch to ON and check the PFD for the L/R AUX FUEL E caution message.
To verify a full auxiliary fuel tank open the auxiliary fuel tank filler and check fuel level.
If the auxiliary fuel tank quantity is in between empty and full, the exact quantity cannot be determined. If possible transfer all fuel to the main fuel tank by setting the ELECT. MASTER switch and the FUEL TRANSFER switch to ON until the L/R AUX FUEL E caution message appears on the PFD. During this procedure ground power must be used or at least one engine must be running. The fuel transfer will take a maximum of 10 minutes.


CAUTION
If the auxiliary tanks are in use, both tanks must be refueled to the maximum level to provide proper information for the pilot about the fuel quantity in the auxiliary fuel tanks.
If the auxiliary tanks are not in use, the pilot must ensure that they are empty.
4. Multiply the individual masses by the moment arms quoted to obtain the moment for every item of loading and enter these moments in the appropriate boxes in Table
