What is the maximum operating temperature for the engines on the ERJ 170/175 during takeoff?

The maximum operating temperature for the engines on the ERJ 170/175 during takeoff is 700°C. This limitation is crucial because exceeding this temperature can lead to engine damage or failure due to overheating. The temperature limit is set based on safety and performance considerations, ensuring that the engines operate efficiently without risking their structural integrity.

Maintaining this temperature is part of the aircraft's overall operational limits designed to protect both the engine and its components during the high-stress conditions experienced during takeoff. It is essential for pilots to be aware of and adhere to these limits as they directly impact the safety and performance of the aircraft.
