Hi again..
Would be really grateful if anyone knew the approximate EPR figures for low level flying on the classic with RB211s! It would be for 280, 250, 220, 200, 180, 160, down to vref..
Much Ta..

Welcome to Pprune, unfortunately you may find that we arent very forthcoming with this type of general question.
Tell us why you want the information and you might find people who will answer you.
Good Luck.

Well, some of us are. ;)
I don't have the books here in front of me, but it'd vary by weight a fair bit. I really would only be guessing, but you typically have about 1.22 - 1.25 ( I think ...) for most configurations for approach.
You normally start thinking about extending flaps when the airspeed is below about 250kts, but again that depends on the landing weight.

If you're simming, then you'll also need another number to fly with - 2.5° nose up.
Fly the ILS with about that pitch angle and the plane will usually just sit there on the glideslope. It's also a typical pitch attitude for cruise.
Also allow a full half minute with the flaps going from 1° to 5° and back, but the rest of the flap movements are pretty quick.
