Engine Pressure Ratio (EPR)

What is Engine Pressure Ratio (EPR)?

A Key Indicator of Jet Engine Performance

The Engine Pressure Ratio (EPR) is a vital metric used to assess the efficiency and performance of jet engines by comparing inlet and exhaust pressures.

Engine Pressure Ratio (EPR) measures the pressure increase across an aircraft engine, typically used in performance monitoring.

• Engine Performance Indicator: EPR is a key metric for assessing an engine's health and efficiency during operation.
• Pilot Monitoring Tool: Pilots monitor EPR readings to ensure engines operate safely and efficiently.
• Maintenance and Diagnostics: Used in maintenance practices to diagnose engine issues and assess overall engine condition.

EPR is important for monitoring and maintaining aircraft engine performance, ensuring operational efficiency and safety.
