747 EPR settings
anyone out there willing to give a little information on approximate EPR settings for the 200 in the approach and landing configuration as well as clean 280 and 250 KIAS respectively?
thanks
thanks
As the first 747s I flew had GEs, I still prefer using N1s to EPR. A good rule of thumb for the GEs on the approach was 60% plus the middle digit of your weight in tonnes. So at 220 tonnes LW you would use 62% and at 270 tonnes, 67%. Now I fly with Pratts, and it seems to work with those too. But not sure about Rollers. Can anyone say if it's the same?

Dan, that's a good one, sounds all right also for the Rollers!
For OEI and TEI, wouldn't it be fair to say about
OEI +7%
TEI +15%
Not that you are supposed to fly by the numbers, but it sure helps in initial training to have an aim to go for.
I also vote for N1 for target, as regarding the figures for fuel flow, EPR and N1, N1 is the only one the pilots have for all engine types (as far as I know).
Funny how the sim in BOH is so much different to fly than the one in MAD, not enginewise but stick and rudder. Which one would be closest to the real thing?
