Aircraft’s empty weight data is unique for each and every Sinus ultralight motorglider produced.

Registration number:
Installed appliances:
Determination of CG
Weight (kg)
Weight’s lever
arm (cm)
Torque (kgcm) Remarks
Basic cfg. emtpy weight
CAUTION!
Each newly installed part or appliance must be registered in the upper table. Also,
new total weight and lever arm of CG values must be entered and position of CG re-determined.
Furthermore, the momentum must be recalculated. This is rather unchalanging to do. First mul-
tiply the new part’s weight by it’s lever arm measured from the reference point (wing’s trailing
edge). Then sum up all momentums and divide the sum by the new total weight.
WARNING!
Aircraft's safe center of gravity position ranges between 20% and 39% of mean
aerodynamic chord and is not affected by cockpit crew weight or weight of fuel on board in any
way.
WARNING!
If your aircraft is equipped with a parachute rescue system, the weight of lug-
gage in luggage compartment is limited to 1 kg if you own the 503 model, 2 kg if you own the
model 582 and 4 kg if you are a proud owner of 912 model.
