A. Item 1: Spoilers status indication R **ON A/C 106-149, 303-399, 401-499,
(Ref. Fig. 003)
**ON A/C ALL
(1)
Case 1 The spoiler is represented out and green, when the spoiler status is transmitted correctly from the FCDC bus, the spoiler is extended and available, also from the FCDC bus.
(2)
Case 2 The spoiler is represented in and green, when the spoiler status is transmitted correctly from the FCDC bus, the spoiler is retracted and available, also from the FCDC bus.
(3)
Case 3 The spoiler is represented out and amber when the spoiler status is transmitted correctly from the FCDC bus, the spoiler is extended and faulty, as transmitted from the FCDC bus.

(4)
Case 4 The spoiler is represented in and amber when the spoiler status is transmitted correctly from the FCDC bus, the spoiler is retracted and faulty, as transmitted from the FCDC bus.
(5)
Case 5 The spoiler is replaced by amber XX when the spoiler status is transmitted as not valid from the FCDC bus, or the information is not transmitted correctly from the FCDC bus.
B. Item 2: Hydraulic system pressure indication
R **ON A/C 106-149, 303-399, 401-499,
(Ref. Fig. 003)
**ON A/C ALL
Case 1 The letter which represents the hydraulic system is normally displayed in green. Case 2 It is displayed in amber when the related pressure is lower than 1450 PSI or when the FWC has transmitted a low press to the DMC. Case 3 The letter is not displayed when the information is not transmitted correctly to the DMC.
C. Item 3: Spoilers status (right)
Refer to the item 1 (left spoilers) as the same principles apply.
D. Item 4: FCDC Message A LAF DEGRADED message is displayed in amber when the FCDC transmits a fault of the LAF function: LAF advisory, LAF degraded aileron, LAF degraded spoiler. It is not displayed when neither of these is valid or when the information is not available from the FCDC bus.

E. Item 5: Aileron position
R **ON A/C 106-149, 303-399, 401-499,
(Ref. Fig. 004)
**ON A/C ALL
Item (A)
A pointer moving along a fixed scale represents the aileron position. It
is normally diplayed in green.
It is displayed in amber when there is a low pressure of the relevant
hydraulic systems, or when an aileron fault is transmitted from both
hydraulic systems concerned.
F. Item 6: Servo control hydraulic pressure
R **ON A/C 106-149, 303-399, 401-499,
(Ref. Fig. 004)
**ON A/C ALL
Item (D)
Two normally green letters represent the hydraulic systems involved (e.g.
GREEN and BLU), they are diplayed in amber when the relevant pressure is
lower than 1450 PSI, as transmitted by the SDAC.
They are not displayed when the pressure value is not transmitted
correctly by the SDAC.
