6.6 Loading and C.G. check

Before flight is important to determine that the aircraft is loaded so its weight

and C.G. location are within the allowable limits.

Aircraft loading and C.G. determination perform as follows:

1. Record actual empty weight, arm and moment to the table.

2. Record weights of pilot, passenger, baggage and fuel to the table.

3. Calculate and record moment for each item using the following formula:

MOMENT (kg mm) = WEIGHT (kg) x ARM (mm)

4. Calculate and record total weight and moment.

5. Determine and record aircraft C.G. using the following formula:

100

AIRCRAFT C.G. = ------- (mm) x -------- (%) of MAC

MAC

6. If loading or C.G. calculation results exceed maximum permitted values,

reduce baggage or fuel weight and repeat calculation.

7. It is important to perform loading and C.G. check without fuel (in case of

total fuel depletion) – most rearward C.G. check.
