Hi everyone just wondering if someone could maybe let me know the following,
I understand at least for the CFM series you advance thrust to 50% check positive engine response before advancing to either FLEX or TOGA as required. The IAE series as I'm aware has a totally different ECAM display with regard to engine thrust settings, how far do IAE variants advance thrust to before either advancing to FLEX or TOGA as required?

Thanks! :)

Set 1.1 EPR instead (but the E/WD still shows N1 mind you...)

We set 1.05 EPR before calling "stable" then advancing to MCT/FLEX. N1 is still shown though.....

(LHR A320 operator thats going to disappear soon)

(but the E/WD still shows N1 mind you...) "the E/WD also shows N1" is more accurate...

Airbus SOP is 1.05 EPR (which is approximately 50%N1) .. and no "stable" call..

I would say 1.05 EPR corresponds to approximately 47% N1, but still for IAE engines according to Airbus you have to look only for the 1.05 EPR.

1.05 EPR is correct. This corresponds with the lever being next to the "T" on the housing but you will soon get used to it without actually looking at it.
