Solely relying on EPR, without the crosscheck of N1 can be a fatal trap. Several T/o accidents can be contributed to the inadvertent miss setting of power at T/O., by using EPR alone.
I like to know what RPM the fan is at.
You only need a blocked EPR probe for e.g., and there goes the EPR accuracy, right there.
Why not just use N1 as the main power parameter.
