At what temperature does the engine's oil system warning activate?

• A. 140°C
• B. 150°C
• C. 160°C
• D. 170°C

Answer: (B)

The activation of the engine's oil system warning is a critical safety feature designed to alert pilots to potential problems with the engine's oil system. In the case of the ERJ 170/175, the warning activates at 150°C. This temperature threshold is established to ensure that any issues relating to oil temperature are addressed promptly to prevent engine damage or failure. When the oil temperature exceeds this limit, it indicates that the oil may not be able to adequately cool and lubricate the engine components, which could lead to overheating and increased wear. The warning system is there for the pilot's awareness and serves as a crucial component of the preemptive maintenance and operational safety of the aircraft. Understanding this limitation helps pilots respond appropriately and maintain engine integrity within safe operating parameters.
