What is the maximum 30-second engine thrust rating for the ERJ 170/175?

The maximum 30-second engine thrust rating for the ERJ 170/175 is indeed 8,729 lbs thrust. This rating is a critical performance specification that allows the aircraft to deliver increased thrust for short durations, particularly during takeoff or for emergency situations, ensuring that the aircraft can maintain safe flight profiles under demanding conditions. This thrust rating is based on the capabilities and certifications of the engines used in the ERJ 170/175, specifically the GE CF34-8E engines, which are designed to handle this level of output for limited periods without risking engine integrity.

Other options, while they may appear plausible, do not reflect the actual engineering specifications for the aircraft's engines. Understanding the correct thrust rating not only reinforces knowledge of performance limitations but also emphasizes operational safety practices during flight planning and execution.
