- Determining weight and balance
General
This section is intended to provide the pilot with the procedure to determine the weight
and balance of the airplane.
▲
WARNING
▲
It is the pilot's responsibility to ensure that the airplane is properly
loaded and that the weight and balance limits are adhered to.
▲
The procedure requires the following data related to the basic characteristics of the
empty airplane to be obtained from the last airplane weight and balance report :
-
the empty weight, expressed in kg or lbs,
-
the moment, expressed in m.kg or in.lbs,
-
the CG, expressed in MAC %
If the airplane empty weight has varied since last weight and balance report (for
example, due to installation of optional equipment), refer to paragraph Determining
empty airplane characteristics to determine new empty weight and the corresponding
moment.
Utilization of weight and balance graph
This procedure determines the airplane weight and balance characteristics for flight.
Select the units for the weight and balance determination, either m and kg, or lb and in,
and use the dedicated form - see figures 6.4.3 or 6.4.4, appropriate to the chosen
units.
1)
Record the basic empty weight
(1a),
moment
(1b)
and CG (MAC %)
(1c)
from
the last weight and balance report - see sample of weight and balance report,
figures 6.4.1 and 6.4.2.
2)
Record the expected loading
(2a)
and compute each associated moment
(2b)
.
3)
Compute zero fuel weight
(3a)
and moment
(3b)
as sum of all the above
weights
(1a)
+
(2a)
and moments
(1b)
+
(2b).
4)
Check value
(3a)
to be below maximum zero fuel weight.
5)
Compute zero fuel weight arm
(5)
and CG (MAC %)
(5c)
using given formulas.
6)
Record the loaded fuel
(6a)
and compute associated moment
(6b).
