Determination of C.G. for the Flight
The Pilot is responsible for proper loading of the aircraft.
The C.G. can be determined by computation or by using the following graph.
The C.G. must always be within limits (compare chapter 2)!
Example for computation:
Method 1 “Calculation”:
Data in the shaded area are taken from the “Wägebericht”.
