•
Z-axis is parallel to the main rotor shaft, positive upward,
•
X-axis is normal to Z-axis in the plane defined by Z-axis and tail
rotor transmission axis, positive rearward,
•
Y-axis is deduced from the two others, so that the XYZ frame is
direct. Positive Y are on the helicopter
right side.
Datum is defined such that main gearbox center coordinates are :
X
= + 2000 mm
Y
= 0 mm
Z
= + 2000 mm
Notes :
- The helicopter is not leveled when on a horizontal ground.
- The tail rotor transmission is angled 2° downward when the
