Some of the supposed differences might be susceptible to an objective test - speeds for instance, and even (theoretically) sustained turn rates.

Agreed 100%

Most testing done by sim pilots is NOT done well..

Such that even they are not able to repeat the test and get the same results..

In short the 'differences' the pilot is 'seeing' and or 'feeling' is due to the sim pilot not the FM

At the moment my prototype autopilot system (http://forums.ubi.com/eve/forums/a/tpc/f...4121016097)has only been tested with a stock install, but there is no reason in principle why it won't work with mods. It needs more work to measure turn rates though, and I suspect that w1ndf4k3r may get there first with this one (see http://allaircraftsimulations.com/forum/...39#p329339).

Actually a guy by the name of LesniHU beat you both years ago with his autopilot program that interfaces via DeviceLink..

His is script based and can do turn rates but is not easy to setup..

Clearly, testing every aircraft in both mod packs would be tedious though.

Which is why I switched to using SJacks zINFOMOD for all performance testing and only used LesniHU's autopilot on results that look questionable, as in a sanity checking of the zINFOMOD results. Thus far I have not fond one zINFOMOD result that was not validated by LesniHU's autopilot

And even if we find differences, all that might result is an argument about which is correct. Given this, I'm not even sure I'd want to get involved in testing, unless there was an agreed way of arriving at a common standard for mod FMs.

The best way to avoid that is to avoid sim pilots methods and stick actual test methods used by the air forces of that time.. The two most popular tests during WWII to test performance was the rate of climb (ROC) results and the top speed per altitude (TSPA) results.. It was only after WWII that they started using the Energy methods to determine the performance of an aircraft.

The neat thing about that is SJack's zINFOMOD provides both those test and more that can be compared to actually WWII test results..

As long as you use the std atm map by Bbury in conjunction with zINFOMOD..

Something the folks over at UltraPack did not realize until it was too late and sheds light on 'why' they felt some FM's needed changing

This would need good intentions, rather than raking over old arguments about who did what and why...

Disagree it is good to point out the errors others made in the hopes that they and others will think twice before making a change to someone else FM before they know the whole story
