The Engine Pressure Ratio (EPR) indicating system consists of one combined P2/T2 sensor and eight pressure ports located in three LP turbine exhaust case struts (24 total).The pressures from these sensors are routed to the EEC pressure transducers. The signals are then converted into a digital format. The Electronic Engine Control (EEC) processes the pressures to form actual EPR (P4.9/P2) ( Engine Pressure Ratio ) and transmits the EPR value to the ECAM system through it digital data bus. Each of the two EEC channels performs this operation independently.
