Thanks..
It nice to know that at least CFM specify tolerance limits. However, the IAEs differ. I just can't seem to find a tolerance limit or maybe it does not exist. Either way, there has to be some acceptable EPR range for continuation for takeoff!
I have heard of at least one European carrier operating IAEs using 0.01% EPR as a guide. However, neither can I locate the origins of this number, nor can I verify its truth.
