1.11.2. Empty weight determination
•
Tools needed: Scales, ramp boards and rests under wheels to level the aircraft.
•
Parts needed: None
•
Type of maintenance: Line
•
Level of Certification needed:
- Aircraft owner (only for ELSA)
- Sport pilot or higher
•
Instructions:
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 (2.0
liters / 0.5 US Gal). The aircraft is weighed without crew 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 POH).
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 POH, Section 6.
10. Up-date the Weight and Balance information table and attach it in the List of the
Supplements (Paragraph 9.2.1) of the POH.
•
Task proper accomplishment check: Push a wing down to rock the aircraft and then repeat
weighting. You should get the same results as before.
