As it is, I assume there's no point, as I don't have MakeRunways installed in XP11. (Can it be??).
Is there any way (and again, since AFAIK MakeRunways won't work in X-Plane, I am guessing not, but it's worth asking the question, just in case) to have PF3 read the runway database for X-Plane instead of FS9 or FSX? Since discovering the joys of X-Plane 11 last summer, I have hardly flown FS9/FSX since! (I am SO happy there's a PF3 plugin for XP11!!! I wish someone would get FDC working there too).
