1 - PASSENGER CABIN TEMPERATURE INDICATION
− Indicates the temperature inside the passenger cabin.
− Digits are green.
− Legends are white.
− Ranges from -10 to 50°C (14 to 122°F).
2 - Cockpit temperature indicatION
− Indicates the temperature inside the cockpit.
− Digits are green.
− Legends are white.
− Ranges from -10 to 50°C (14 to 122°F).
3 - BLEED TEMPERATURE INDICATION
− Indicates the bleed air temperature downstream of the pre-
cooler on the left and right engine.
− Scale and Pointer:
− White for the scale, below 260°C (500°F) to indicate
potentially low thermal energy availability to the anti-icing
system. Amber for the pointer, only if the pointer is in the
white band of the scale and the message “BLD 1 (2) LOW
TEMP” is shown on EICAS.
If the pointer is in the white band of the scale and the
message “BLD 1 (2) LOW TEMP” is not presented in the
EICAS, the pointer will be green.
− Green from 260 to 305°C (500 to 581°F) to indicate the
acceptable range.
− Red above 305°C (581°F) to indicate an overtemperature
condition.
− In case of an outlet temperature sensor failure, the
respective pointer is removed from the vertical temperature
bar.
