An advisory only appears in phases 2 and 6, when the fuel temperature is :
• Above 45 °C for the inner cell, or 55 °C for the outer cell.
• Below -40 °C.
It becomes amber, and the ECAM displays a caution, if the temperature goes above the high
limit or below the low limit.
(7) Fuel quantity indication
‐ It is normally in green.
‐ An amber line appears across the last two digits, when the FQI is inaccurate (Refer to

transfer valves fail to open when the inner is at low level.
‐ The center tank indication is boxed amber, if both center tank pumps are failed, or are
switched OFF.
