(4) Z measurement
Adjust a sight tube at Z = -3500 mm (137.7953 in.) from the
horizontal datum of the fuselage.
Write down the variations between:
- the datum of the rods of the points 10 and 13,
- the scanning plane of the sight tube.

R NOTE : For the check of the point 10, measure the radome.____
R (1) Datum lines
R (a) Make a projection of the points 10, 11A, 12 and 13 to the floor
R with the SET - PLUMBS BOBS (98A08001004000).
R (b) Move the points 11A and 12 to the left by the dimension Y = 47.36
R mm (1.8645 in.).
R NOTE : The dimension 47.36 mm (1.8645 in.) at the points 11A and____
R 12 is due to the angular position of the tool. You only
R use this dimension when you measure with the SIGHTING RODS
R SET (98D08103500000) installed on these points.

R (c) Move the points 10 and 13 to the left by the dimension Y = 45 mm
R (1.7716 in.).
R (d) Align a cord through the points 11A and 12 with the HOLDING SET -
R MEASURING CORD (98A08001005000).
R (2) Y measurement
R (a) Measure the right and left variations of the points 10 and 13
R from the cord.

R (3) X measurement
R (a) Write down the X position of the bottom fuselage points in
R relation to the point 11A.
(4) Z measurement
