It is normally in green.
It becomes amber, if the BMC detects an overheat or low temperature.
Overheat : Temperature exceeds :
‐ 290 °C for more than 5 s, or
‐ 270 °C for more than 15 s, or
‐ 257 °C for more than 55 s.
Low temperature is detected, if the bleed temperature drops below 150 °C, and if wing
anti-ice is on. Low temperature may, however, only be due to low outside air temperature.
(4) APU BLEED VALVE
Displayed only if the APU MASTER SW is ON.
Crossline - Green : APU valve not fully open and APU BLEED pushbutton is OFF
Crossline - Amber : APU bleed valve is not fully open and APU BLEED pushbutton is
