Weighing
1. General
Only operate the airplane within the permitted range of weight and center of gravity limits. This will give
good flight performance and good handling qualities. It is also necessary for safe operation of the
airplane.
If you make any changes to the airplane that may alter the weight (or the center of gravity), then you
must calculate the new weight of the airplane. You must also calculate the center of gravity.
Only an approved person can weigh the airplane. The national Airworthiness Authority of the country
where the airplane is registered gives approval for persons who can weigh the airplane. It also gives
the time limits for when the airplane must be weighted.
Use the Weighing Report when you do the weight and balance calculations (refer to Figure 3).
You can use mechanical scales or electronic weighing units to weigh the airplane. Electronic weighing
units give more accurate and consistent results. They are also easier to use. You must obey the
manufacturer's instructions for using the scales or weighing units.
The reference plane for the DA 42 NG is a transverse, vertical plane in front of the airplane. It is at right
angles to the horizontal reference line. The reference plane lies at 2196 mm (86.46 in) in front of the
stub-wing leading edge at the wing root rib.
