IL-2 Compare with Great Battles airplanes data for top speeds in Manuals, Tutorials, Guides and Tips Posted 3 minutes ago · Edited 3 minutes ago by CountZero On 1/16/2020 at 1:41 PM, hnbdgr said: Thanks OP, so the ROC data is taken from the game directly? Would it be possible to calculate performance on emergency power according to engine HP increase or another forumla? i did notice they place there for some new airplanes emergancy power, insted like it was before for most combat... for example for tempest it looks like this: // Тест в МСА, режим боевой (3700/+9), топливо 100%, радиатор открыт ////// ClimbTime = <float ALTITUDE>, <float TIME> ClimbTime = 0, 0 ClimbTime = 1000, 50 ClimbTime = 2000, 104 ClimbTime = 3000, 167 ClimbTime = 4000, 233 ClimbTime = 5000, 301 ClimbTime = 6000, 378 ClimbTime = 7000, 470 ClimbTime = 8000, 587 ClimbTime = 9000, 754 ClimbTime = 10000, 1049 and then i just placed in il-2 compare ROC numbers in seconds i get when i just devide 1000 by seconds betwen 1k intervals from file, so some airplanes have climb numbers on combat some on emergancy and so on. I dont know if you would be able to make calculations to get emergancy for ones that had only combat or not, nor i know how Devs got numbers i used from thuouse files, i belive they have their own AI who does all testing so they are most accurate. To me to do climb tests manualy like i did for speeds looked to mutch time consuming, and i would never be able to get it correct so i just used numbers from thouse files for what they had. Its usealy one engine setting per airplane there. From what i pick up on forums DerSheriff has some good climb data for airplanes on his discort, so if im not wrong maybe he can give you beter info regarding climb performances of airplanes.
