9X and 10X versions just now updated. A couple small changes to the panel. Small adjustments to the AP engage buttons, and putting auto-throttle, auto-speed engage buttons over on the co-pilot side (they who would be responsible for speed management anyway). This also has two 3d emit lamps in the cockpit and, well, simply put.. your mileage will vary. x-plane 970 and 1011, day and night appearance, and 1011 hdr-on vs hdr-off, all widely vary. I was reminded that interior lamps like that start out at about 50% intensity which makes things appear pretty dim unless you know to, think to, reach down and dial up the interior FLOOD rheostat.
I combed through most of the systems #'s to try to un-bone the systems changes within x-plane that crept up recently as noticed on some planes. So for my personal consistency, I went through all the systems #'s to make things uniform at least in the methodology. I double checked the engine values. among my two or three very deep jet engine specifications sources, plus the GE engine data sheets, I haven't seen an exact bypass_ratio specified. I'll look some more, esp for the antique well-documented engines of the LJ25 and G-II. I'm still considering some other liveries for the LJ25, not sure exactly what though yet.
Must try!
