The green needle can vary between the position LO and the position
HI. The LO position corresponds to 80% of airflow to the air
conditioning packs, HI position to 120%.
When there is no flow, the needle is frozen at the position 80 %.
(2)
Case 2 The needle is amber when the pack flow control valve is fully closed
When there is no flow, the needle is set at the position corresponding to the LO limit.
(3)
Case 3 When the pack flow (or the cabin pressure, or the cabin altitude) is not available from the SDAC, the needle is replaced by amber XX.
The scale, the indications HI and LO are white.

Case 3 It is replaced by amber XX when the pressure is not available from the SDAC.
The pressure value can vary from 0 to 98 PSI by steps of 2 PSI. The unit PSI is always displayed in cyan.
