The L or R ENG ICE TEMP LO caution light indicates engine inlet bleed air temperature is:

• A. Too high
• B. Too low
• C. Normal
• D. Not available

Answer: (B)

The message is about the temperature of engine inlet bleed air and whether it’s within acceptable limits for the anti-ice and related systems. When the L or R ENG ICE TEMP LO light is on, it means the sensed inlet bleed air temperature is below the minimum required. Cold bleed air won’t provide adequate heating for inlet ice protection, so the system warns you with this caution. This is why “too low” is the correct interpretation. If the temperature reading were too high, you’d expect a different indicator; and if it were normal, the light wouldn’t illuminate. A “not available” condition would suggest a sensor fault, not a normal low reading.
