Hello, i am working on importing a very classy and nice airplane (A****o PA-22) from FSX:A to MSFS (premium deluxe updated), but i am having a problem.
The propeller efficiency table, in MSFS, looks like this:
-----
prop_efficiency_table = 0.000000:0.000000:0.134457:0.268913:0.403370:0.530311:0.657251:0.784192:0.911133:0.957964:1.004795:1.051626:1.098457:1.153380,12.000000:0.099458:0.663054:0.461243:0.320857:0.227773:0.161694:0.114785:0.081485:0.071809:0.063282:0.055768:0.049145:0.042374,13.600000:0.070380:0.497662:0.703801:0.587003:0.494579:0.416708:0.351097:0.295817:0.277699:0.260690:0.244724:0.229735:0.213321,15.200000:0.055841:0.372274:0.644797:0.744547:0.664186:0.592498:0.528547:0.471499:0.452045:0.433393:0.415511:0.398367:0.379159,16.799999:0.047118:0.304552:0.561433:0.730433:0.785294:0.719951:0.660045:0.605124:0.586037:0.567552:0.549651:0.532314:0.512677,18.400000:0.041302:0.260899:0.495087:0.678591:0.788317:0.826041:0.770121:0.717987:0.699658:0.681797:0.664392:0.647431:0.628090,20.000000:0.037148:0.199130:0.387608:0.555352:0.686590:0.785077:0.846113:0.866787:0.850768:0.835045:0.819612:0.804465:0.787056,21.600000:0.032545:0.189792:0.370396:0.533068:0.663085:0.764476:0.832865:0.865301:0.867858:0.852596:0.837603:0.822873:0.805927,23.200001:0.028964:0.181303:0.354626:0.512338:0.640644:0.743803:0.817766:0.859631:0.866601:0.868929:0.854355:0.840024:0.823524,24.799999:0.026100:0.166249:0.326371:0.474464:0.598317:0.702509:0.783616:0.838972:0.852501:0.862208:0.868050:0.870000:0.854355,26.400000:0.023756:0.158618:0.311933:0.454816:0.575832:0.679680:0.763264:0.824093:0.840404:0.853297:0.862720:0.868635:0.871071,28.000000:0.021804:0.158813:0.312316:0.455376:0.576540:0.680516:0.764203:0.825106:0.841437:0.854346:0.863781:0.869703:0.872142

I am using the help of some tools (AirEd and Air Wrench) to get the proper numbers based on real world data, but the result they give me are differently formatted, like this:

So…, how do i “translate” the old AIR file format to the proper MSFS values?
Thanks a lot for your help.
Think I read somewhere that the old Air files needed to be compressed for MSFS 2020 to read them.
Isn’t it just a case of deleting spaces and inserting comas? Don’t quote me I haven’t searched for it.
