SECTION 3
WEIGHT & BALANCE
3 Introduction
This section describes the procedure for establishing the basic empty weight and moment of the aircraft. Loading procedure
information is also provided.
3.1 Aircraft weighing procedures
3.1.1
Preparation
•
Carry out weighing procedure inside closed hangar
•
Remove from cabin any objects left unintentionally
•
Insure Flight Manual is on board
•
Align nose wheel
•
Drain fuel via the specific drain valve
•
Oil, hydraulic fluid and coolant to operating levels
•
Move sliding seats to most forward position
•
Raise flaps to fully retracted position (0°)
•
Place control surfaces in neutral position
•
Place scales (min. capacity 200 kg 440 pounds) under each wheel
•
Level the aircraft using cabin floor as datum
•
Center bubble on level by deflating nose tire
•
Record weight shown on each scale
•
Repeat weighing procedure three times
3.1.2
Calculate empty weight Weighing
•
Record weight shown on each scale
•
Repeat weighing procedure three times
•
Calculate empty weight
3.1.3
Determination of C.G. location
•
Drop a plumb bob tangent to the leading edge (in non-tapered area of one half-wing, approximately one meter
from wing root) and trace reference mark on the floor.
•
Repeat operation for other half-wing.
•
Stretch a taught line between the two marks
•
Measure the distance between the reference line and main wheel axis
•
Using recorded data it is possible to determine the aircraft's C.G. location and moment (see following table)
