Hi, a runway has always two physical threshold coordinates. Therefore both ends have to be stored in the navigation database. For the PMDG 777 RWY N/A issue, I verified today again, that deleting ARPT_RWY.dat solves the problem, as the 777 regenerates it containing the RWY 36 at EDDF. If that shouldn´t work delete the FMCPWP and the SID/STARs folder completely and reinstall the airac. For some reason some older files could create trouble: http://forum.avsim.net/topic/4532
