Hi,Is there anybody who could help me out with the calculations for EPR. The FS own EPR value gives me strange values, it goes below 1 when I'm up in the air which is to say the least wrong!Thanks/Matts

Try asking here:http://www.avhistory.org/scripts/MegaBBS/f...w.asp?forumid=5if they don't know, then nobody does (including Microsoft).

Based on regressions of a 727 FM simulator's values. I'm planning to test the formulas with an XML gauge soon. Only FS variables are needed to calculate approprite EPR. I'd expect the same formulas with different constants would work for many turbines. With these formulas, EPR is based on EGT. So, an accurate EGT will be calculated first. The FS2K2 EGT is also inaccurate. I'm often in the Avhistory AIR file forum (url in other message). So, that's the place to learn of any results. Ron
