A. Permitted Aerodynamic Tolerances between the Slats 1 thru 5
(1)
Check the slat end step tolerances as follows:
(a) For the slat 1, measure and write down the slat end step dimensions:
-
at the inboard end of slat 1 at points 1 and 4 (2 dimensions)
-
at the outboard end of slat 1 at points 1, 2, 3, and 4 (4 dimensions).
(b)
For the slats 2 thru 5, measure and write down the slat end step dimensions at points 1, 2, 3, and 4 (20 dimensions).
(c)
Compare the 26 dimensions:
-21 of the 26 dimensions measured must be between the general tolerance limits given in the table J
-3 of the 26 dimensions measured can be between the general tolerance limits given in the table J +/- 0.5 mm (0.0196 in.)
-2 of the 26 dimensions measured can be between the general tolerance limits given in the table J +/- 1.5 mm (0.0590 in.).
(2)
Check the slat upper-trailing edge to 'D' nose step tolerances as follows:
(a)
For the slat 1, measure and write down the dimension X at points A, B, C, D and E (5 dimensions).
(b)
For the slats 2 thru 5, measure and write down the dimension X at points B, C and D (12 dimensions).
(c)
Compare the 17 dimensions X:
-14 of the 17 dimensions X must be between +/- 0.5 mm (0.0196 in.) of each other
-3 of the 17 dimensions X can be between +/- 1.0 mm (0.0393 in.) of each other.
(3)
Check the slat lower-trailing edge to 'D' nose step tolerances as follows:
(a)
For the slat 1, measure and write down the dimension Y at points F, G, H, J and K (5 dimensions).
(b)
For the slats 2 thru 5, measure and write down the dimension Y at points F, G and H (12 dimensions).
(c)
Compare the 17 dimensions Y:
-11 of the 17 dimensions Y must be between +/- 1.0 mm (0.0393 in.) of each other
-4 of the 17 dimensions Y can be between +/- 2.0 mm (0.0787 in.) of each other
-2 of the 17 dimensions Y can be between +/- 3.0 mm (0.1181 in.) of each other.
(4)
Check the slat lower-trailing edge to 'D' nose gap as follows:
(a)
For the slat 1, measure the dimension L at points F, G, H, J and
K.
(b)
For the slats 2 thru 5, measure the dimension L at points F, G and H.
(c)
The dimension L must be 5.0 mm (0.1968 in.) +/- 2.0 mm (0.0787 in.).

SLATS ELECTRICAL CONTROL AND MONITORING - DESCRIPTION AND OPERATION
___________________________________________________________________
1. General_______
The electrical control and monitoring system of the slats has:
-
a manually operated slat/flap control lever
-
a Command Sensor Unit (CSU) 51CV
-
two Slat and Flap Control Computers (SFCC1 and SFCC2) 21CV, 22CV
-
two electrically controlled valve blocks 25CV(26CV) installed on the slats Power Control Unit (PCU) 6001CM (Ref. 27-84-00)
