July 18, 200520 yr Dear PMDG Team !I've read in this forum that originally there will be no EPR Gauge in your 747-400 Cockpit. Other Developers like Level-D also haven't done a EPR Gauge in their Cockpit. Is there a difficulty in programming it?I remember that PSS simulated it in their 747-400.I hope there's a way to do it for you, would be nice.ThanksChris
July 18, 200520 yr i would really like this to be modelled as well...however, it is apparently very hard to model due to limitations of FS, and PSS could do it because theirs was a stand alone sim. :(if i am wrong feel free to correct me
July 18, 200520 yr EPR stands for Engine Pressure Ratio. EPR is the primary method of measuring the power produced by Rolls Royce and Pratt & Whitney engines. It is basically the relationship between engine inlet pressure and turbine exhaust pressure. Lee Holland
July 18, 200520 yr Just as a sidenote. The EPR gauges you have seen in other (numerous even) aircraft use the MSFS internal EPR which doesn't resemble reality so well that it could be used for any serious simulator add on.I won't comment on the difficulties of creating a true EPR gauge for MSFS. The experts can throw in their PPL(A)

July 18, 200520 yr Tero,What about Stellan Hilmerby's EPR gauge in the DC-9? Have you tried it. I have no experience with EPR ratios so can't really tell if it's accurate or not. I would be surprised though if Stellan, as a former niner skipper, did release something which didn't reflect the real operations on the DC-9.If you haven't tried it.

July 18, 200520 yr Mats,I don't know, if it's accurate or not and I'm in no position to evaluate, but I do know that FDE gurus like Ron Freimuth etc. have battled for years to create even ONE engine model EPR correctly. I would be surprised if Stellan had matched his EPR gauge to real-life performance correctly in all atmoshperic conditios/altitudes etc., which is, in essence what an accurate EPR modelling should do.Tero PPL(A)
