620 - ATPL Question Bank in English - Which statements about an engine using engine pressure ratio (EPR) as its thrust-setting reference are correct? 1) EPR is the ratio of turbine-discharge total pressure to compressor-inlet total pressure. 2) A single EPR value guarantees the same net thrust at every Mach number and altitude. 3) Accurate power setting requires the applicable engine/aircraft EPR reference and the specified ambient-condition corrections. 4) EPR is the pressure difference obtained by subtracting compressor-inlet pressure from turbine-discharge pressure. 5) Ice blocking the inlet-pressure sensing probe is guaranteed to make indicated EPR lower than actual EPR. Select all the correct statements.
