6.2 Aircraft Weights _________________________________
If ANY changes to the delivery-configuration of the aircraft are made, the empty-
mass must be determined again. This is needed for all of the following
calculations.
The state of the aircraft and its equipment when weighing must be defined
precisely.
More information about weighing the aircraft is given in the maintenance manual
(STEMME Doc.-No.: P500-006.000).
6.2.1 State during Weighing
• Installed equipment according to the current equipment list
• No loose ballast
• Aircraft dry, including operating-fluids:
Brake-fluid
Amount of engine-oil (0.5 – 0.8 US gal / 2 – 3 liters)
Coolant (0.63 – 0.66 US gal / 2.4 – 2.5 liters)
Non-useable fuel (0.55 US gal / 2.1 liters + 0.3 US gal / 1 liter, optional)
The aircraft’s empty-mass and empty-CG-location are determined using the
following method. Every wheel of the landing-gear is placed in a weighing scale
(left main-gear: m
L
, right main-gear: m
R
, front gear: m
F
). The aircraft’s
longitudinal-axis will be aligned in the manner described by the following
diagram.
