Hi Terry,I am working on an airport to import into the PMDG74x and finally managed to import the runways and they show up...but they are not aligned nor am I at the correct end of the runway per the map(easy fix). The reciprocals also do not line up which is disconcerting. In the arpt.dat the runways are listed as lat/long but after the long there is another section ie. -98.646683000.0035401886 what is that?Here is the data for my runways. Could you help me convert the Long to the proper format?RWY MAG (TRU) LENGTH RWY START LAT/LONG Corrected Format?35L 347 (360) 12000 37.965877 -116 03.023213 AFC335L34712000 37.998790 -116.xxxxxxxxx.xxxxxxxxxx17R 167 (180) 12000 37.998790 -116 03.023213 AFC317R16712000 37.965877 -116.xxxxxxxxx.xxxxxxxxxx35R 347 (360) 10000 37.971350 -116 02.875813 AFC335R34710000 37.998777 -116.xxxxxxxxx.xxxxxxxxxx17L 167 (180) 10000 37.998777 -116 02.875813 AFC317L16710000 37.971350 -116.xxxxxxxxx.xxxxxxxxxx06 057 (070) 20000 37.964185 -116 02.807295 AFC306 05720000 37.982944 -116.xxxxxxxxx.xxxxxxxxxx24 237 (250) 20000 37.982944 -115 58.897552 AFC324 23720000 27.964185 -115.xxxxxxxxx.xxxxxxxxxx08 077 (090) 15200 37.982842 -116 02.258370 AFC308 07715200 37.982842 -116.xxxxxxxxx.xxxxxxxxxx26 257 (270) 15200 37.982842 -115 59.416320 AFC326 25715200 37.982842 -115.xxxxxxxxx.xxxxxxxxxxBest RegardsMike
