BTW, thx to two posts at AVSIM, you can now test the native slopped runways available in vanilla P3D v5:
LFHU, KAVX, KCOD, LFKD, LFKX, LSGK, LFMB, EGUO, LFFC, VYKL. VNFT, VNBJ, VNLK .
Would be interested in finding out how PSX.NET P3D Externalsim deals with those - assuming they're ok for 744 operations :-)
