Mass and Balance DA 42 AFM
Page 6 - 6 Rev. 8 15-Dec-2017 Doc. No. 7.01.05-E
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.
