Refer to Section 6.4.4 for a graphical illustration of the CG limitations.
WARNING
Exceeding the center of gravity limitations reduces the controllability and stability of the airplane.

 


2.9 APPROVED MANEUVERS
The airplane is certified in the Normal Category in accordance with JAR-23.
Approved maneuvers 1) all normal flight maneuvers;
2) stalling (with the exception of dynamic stalling); and
