What Does EPR Stand For?
EPR stands for Engine Pressure Ratio
Engine Pressure Ratio (EPR) is a performance metric used to assess the efficiency and power output of an aircraft engine. It is defined as the ratio of the pressure of the exhaust gas leaving the engine to the pressure of the intake air entering the engine. EPR provides valuable insights into engine operation, helping engineers optimize performance and fuel efficiency while monitoring operational limits during flight.
