3.6 Weighing the airplane and C.G. calculation
WARNING
Never exceed the maximum takeoff weight and c.g. range for any configuration of crew, fuel and
baggage as shown in the flight manual.
The removal or addition of equipment may result in changes to the center of gravity and empty
weight of the aircraft. The permissible useful load can also be affected. In such case a new weight
and balance is necessary to determine the new empty weight and center-of-gravity position. The
new empty weight and C.G. position should be recorded in the Flight Manual, Section 6., Weight
and Balance Record / Permitted Payload Range. Then a new permitted crew weight for fueling
and baggage must be computed and recorded. The cockpit placard "Load Limits" should also be
up-dated.
3.6.1 Empty weight determination
The empty weight of an aircraft includes all operating equipment that has a fixed location and is
actually installed in the airplane. It includes the weight of the painted airplane, accumulator,
standard and optional equipment, full engine coolant, hydraulic fluid, brake fluid, oil and unusable
fuel 2.9 l. The aircraft is weighed without crew, fuel and baggage.
The following weighing procedure is recommended:
1. Remove excessive dirt, grease, moisture from the airplane before weighing
2. Weigh the airplane inside a closed building to prevent errors due to wind
3. Place the scales, calibrate zero
4. Place the airplane on the scales (use boards to run on the scales or lift the airplane - see
airplane jacking)
5. Place the airplane in a level flight position (use suitable rests under the wheels)
6. Check the configuration for weighing (e.g. empty weight);
7. Weigh the airplane and record the values in Weight and Balance Record (make a copy of
standard Record included in section 6 Appendices).
8. Compute the weight and C.G. position according to the formula Weight and Balance Record
9. Compute and record permitted crew weight for fueling and baggage - see Pilot's Operating
Manual par. 6.2.
10. Up-date the placard "Load Limits" (make a new one) and attach in the cockpit.
