8. 

Weight and Balance 

8.1   Introduction 

Consult the specific weight and balance report for your individual 
aircraft. It may be possible with some combinations of crew, fuel and 
baggage weight to go outside of CG limits. The pilot must familiarise 
themselves with the typical load cases of their aircraft to establish 
when such a case can occur, and be able to carry out a weight and 
balance check. 

In addition, pilots should be aware that stick forces and displacements 
will become lighter with aft CG (typically a heavy crew and full fuel) and 
heavier with forward CG (typically low fuel, light pilot only).  Also at aft 
CG, the hands-off stability will be reduced.  Flying outside of the 
permitted CG limits at either extreme is potentially extremely 
dangerous and should not be attempted in any circumstance.  

8.2  CG Datum   

The Nynja 600 CG datum is the main wheels axle centre. 

8.3    GG Limits 

Aft limit:         0.197m forward of datum (positive) 

Fwd limit:       0.367m forward of datum (positive) 

8.4   CG moment arms (m) 

Nose wheel:     1.4 forward of datum (positive)   

Fuel:   

    0.35 aft of datum (negative) 

Adj. Seats:      Rear most position 0.15 forward of datum (positive) 

 

   

            Most forward position 0.22 forward of datum (positive) 

Baggage bag:  0.35 aft of datum (negative) 

8.5   Weighing   

The Nynja will have been weighed when first built, and must be re-
weighed at intervals as laid down by the BMAA and CAA. Weighing 
should be carried out by a BMAA 3-axis inspector.  A copy of the 
weight and balance report must be retained in this manual at Annex B.
