(1)
Case 1
The temperature is normally displayed in green.
(2)
Case 2 The temperature is displayed in amber when an over temperature or a low temperature signal is received by the SDAC.
(3)
Case 3 The temperature is replaced by amber XX when the value is not available from the SDAC.
The temperature can vary from 0 to 510 .C by steps of 5 .C. The unit .C is always displayed in cyan.
M. ENG number
(Item 12)
The engine number is normally displayed in white. It is displayed in amber when the DMC receives from the engine busses the signal: engine below idle. When this information is not available the engine number is displayed in white.

**ON A/C ALL
Transfer of air bleed is achieved from the IP stage of the engine HP
compressor by the IP bleed check valve.
The valve indication can be:
(1) Case 1 green and open when the bleed valve is normally not fully closed as commanded (all the other following cases are not valid).

R **ON A/C 106-149, 303-399, 401-499,
(2) Case 2 green and closed the bleed valve is normally fully closed as commanded, for at least 5

Case 3 amber and closed the bleed valve is abnormally fully closed (for at least 5 s) and there is a PRV LOW REGULATION (information supplied by the BMC to the DMC via the SDAC).
(4)
Case 4 amber and open the bleed valve is not fully closed and there is an engine pressure reg valve disagree from the BMC via the SDAC.
(5)
Case 5 XX amber: the bleed valve position (supplied by the BMC to the DMC via the SDAC) is not available.
IP indication is always white.
The duct upstream of the engine bleed valve is amber if the related valve is closed and amber, otherwise it is green.
The duct downstream of the engine bleed valve is amber if there is a PRV LOW REGULATION and the valve is closed for at least 5s, otherwise it is green. The ducts are not displayed when the valve status is not available from the SDAC.
