3. Weighing
With the aircraft level, record the weight shown for each load cell making any adjustments
required for zero error or cell calibration. Perform at least two independent weighings (removing
the aircraft from the load cells before each weighing) such that the difference between two
consecutive weighings doesn’t exceed the local air regulatory requirements.
4. Weighing Arms
Standard arms are provided in the tables in Figures 6-1A and 6-1B for each of the above
mentioned weighing procedures and may be used provided the aircraft is weighed in accordance
with these procedures.
5. Calculation
Use the weights and the measurement obtained to calculate the Empty Weight and Longitudinal
Centre of Gravity location (C of G). The sample forms given in Figures 6-1A and 6-1B may be
used to assist in correctly recording and calculating these weights.
NOTE:
Empty weight includes unusable fuel and full oil.
6.2.2 Weight and Balance Record
Subsequent to each weighing and the establishment of new weight and balance data, the
revised data is to be recorded in the “Record of Empty Weight and Empty Weight Centre of
Gravity Alterations” section of the airframe log book. Additionally this section of the airframe log
book is to be used to calculate and record any subsequent changes to the weight and balance
data that may occur as a result of the installation or removal of equipment, or of changes to the
aircraft structure.
The “Record of Empty Weight and Empty Weight Centre of Gravity Alterations” (Figure 6-2) is
to be amended after every change in weight and balance so that a continuous history of the
current weight and balance data is available to the pilot. The latest entry will therefore be the
current data.
