Baggage and CG
The amount of baggage you can carry in the baggage behind the seats is limited by the center of
gravity of the empty aircraft and by the MTOM.
To calculate how much the c.g. shifts because of added baggage into the solid baggage compart-
ment aft of the cabin use the following formula:
where:
Gtotal is the aircraft empty weight,
CGmm is the position of CG of empty aircraft in millimeters (mm),
Gbags is the weight of the baggage,
Lbags is the lever arm from the datum to baggage area (1160 mm).
Again, express the new c.g. in percentage of MAC:
where:
CGwith.bags is the position of CG now with bags in millimeters (mm),
R is the difference between wing’s leading edge and MAC’s leading edge (40 mm),
MAC is the Mean Aerodynamic Chord (900 mm).

We now have the data of c.g. of the sample aircraft with 10 kgs (22 lbs) of baggage. You can recalcu-
late the formulas using the weights and c.g. of your empty aircraft and the planned amount of bag-
gage aft of the cabin for your flight.
CAUTION: The baggage weight limitations in this manual represent fool-proof limits for safe
operation, even without special c.g. calculation. However, the actual baggage weight limitation is
different of each individual aircraft and can be determined using the above formulas. The decision
of how much baggage to carry on a flight is the pure responsibility of the pilot in command!
WARNING! Always make sure that the baggage is placed fixed inside the baggage area.
Movements of baggage in-flight will cause shifts of center of gravity!
WARNING! Do not, under any circumstances attempt to fly the aircraft outside the allowable
c.g. limits! Allowable in-flight c.g. range is between 10 7/16'' (267 mm) and 14 1/2'' (368 mm), mea-
sured from the wing's leading edge backwards.
WARNING! Maximum takeoff weight (MTOM) MUST NOT, under any circumstances, exceed
1212 lbs (550 kg).
