WEIGHT AND BALANCE
6.1 INTRODUCTION
The aircraft weight and determination of aircraft weight is extremely important to be in
proper balance, because maneuvering and controllability of aircraft depends on C.G. position
and distribution of payload. There are some limitations about payload but for any case in
this manual, for example baggage with weigh of 20 kg.
6.2 WEIGHT AND BALANCE RECORD PERMITED PAY LAOD RANGE.
Aircraft weighing procedure need to be performed when aircraft is leveled on plane surface.
The all operating fluids are in recommended boundaries, with unusable fuel in fuel tanks.
Determining of center of gravity is in respect of leading edge of the wing, as wing is
rectangular, there are the same where respect point is, but according aviation standards the
point is at the half of wing span.

Figure 6 – 1 showing weight and balance record and permitted C.G. range of empty aircraft.
Permitted range of C.G. for empty airplane is 23-27% of MAC or 292 – 340 mm from l.e.
WARNING
If C.G. isn’t in allowed range further exploitation is prohibited
