Hi, before I begin, many thanks for all the amazing contributions you have made to make this hobby so much better, I truly appreciate it.
I am just getting into P3d flight dynamics. I own a home simulator and am trying to get my aircraft to behave as much as possible as the real thing. I am quite fortunate in that I own an FDS Jetmax 777 rig and have had quite a few hours in the BA 777 simulator at Heathrow.
With the advent of the sim1.dll modification via an FSUIPC lua file, we are now able to modify the ground handling in the simulator, taxiing in treacle is no longer an issue. What I have found though is by setting GE90 engine data into my airfile still doesnt yield the rolling friction I would expect when using the ball park 0.025 figure others have quoted. I find this figure is still too high because I know the weight and breakaway thrust a 777 needs to get moving, when this is set in table 1506 the aircraft doesnt behave as expected.
Request; would it be possible to make a change to your advanced jet performance calculator/roll power requirements tool? It would be very useful for me if the Friction Coefficient was a user editable field (as ooposed to the sim1.dll number) so that I can find the mathematical sweet spot for the friction coefficient based on the research I have conducted and the ge90 performance tables I have. So I am trying to find the rolling friction coefficient in P3d by reverse engineering.
I am aware that modifying sim1.dll will throw all of the other engine ground handling airfiles out of balance but i am not concerned here as I modify my own airfiles based on real world data, AI aircraft will be modified also.
Many thanks for your time
