1. Preparation and Conditions
1.1. The fuselage weight must be determined including rudder, back rests with cushions or equivalent upholstery, seat
cushions, canopy, standard tool kit in baggage compartment behind backrest, Logbook and Flight Manual. Replenish
oil and coolant if necessary. Fixed ballast must be installed, loose ballast must be removed.
1.2. Wing weight must be determined with bolts and 1.4 l / 0.31 imp. gal (unusable volume).
1.3. Fixed supplementary equipment must be installed.
1.4. Points 1.2 through 1.4 must be observed if an overall weighing of the powered glider is performed. The canopy has
to be closed during weighing.
1.5. If weight and moment arm of additionally installed or removed items is known exactly, the new CG may be
determined numerically (see point 4.2)
