6. WEIGHT AND BALANCE
6.1.
Empty aircraft weight and center of gravity
determination
The aircraft is wieghted standing on main wheels – all tyres must have
the correct size and pressure. The aircraft in this case leveled for the
purpose of c.g. determination. The reference plane is leading edge of
wing at half of wing span. All operating fluids must be filled to the max
volume and also unusable amount of fuel must be in the fuel tanks.
The following values has to be measured:
Reaction of the nose wheel
R
1
= kg
Reaction of left main wheel
R
2L
= kg
Reaction of right main wheel
R
2P
= kg
Distance of the nose gear from reference plane:
X
1
=
mm
Distance of main landing gear from reference plane:
X
2
=
mm
Empty weight of the aircraft is calculated as follows:
