In this subsection, the procedure to be used for the determination of aircraft weight
and balance in flight is described. The weight and moment obtained must fall within
the approved Weight-Moment Envelope (Figure 6-3). The procedure explained
requires the use of:
- Aircraft Weighing Report (I/II)
- Weight and C.G. - Form (Table 6-1)
- Loading Diagram (Figure 6-2)
- Weight-Moment Envelope (Figure 6-3)
An example calculation is provided to help understand the method.

To determine weight and balance for flight, proceed as follows:
1. Read the most recent values of the Empty A/C weight and corresponding
moment from the Aircraft Weighing Report and write them in the Weight and
C.G.- Form (Table 6-1).
2. Write the weight and moment of the pilot/co-pilot in the Weight and C.G. - Form
(Table 6-1). Calculate the moment as:
Moment = weight X arm where the arm is read in Table 6-1.
Alternatively, the moment can be read from the Loading Diagram (Figure 6-3).
It is strongly recommended to perform a cross-check with
Loading Tables (Table 6-3) to assure an accurate loading value.
3. Repeat the procedure described in 2 for the fuel and baggage loads.
4. The total weight/moment is obtained summing all weights/moments; report take-
off condition (weight and moment) in the Weight and Balance C.G. - Form
(Table 6-1).
5. To obtain the landing weight and moment, subtract from the take-off condition
values the weight and moment of the total fuel required. These values are
reported in the Weight and Balance C.G. - Form (Table 6-1). Write the landing
values Weight and Balance C.G. - Form (Table 6-1).
Locate on the Weight-Moment Envelope (Figure 6-4) the points (weights and
moment) corresponding to the take-off and landing conditions. If the points fall
within the envelope, the loading condition meets the weight and balance
requirement
