Dear George:The ILS in FS2004 is part of the airport data and with an hexadecimal editor we can change the coordinates to the APxxxx.bgl files.I have use the bgl2asm to see the FS9 airport data, i have changed the position of the airport refernce point and all the APT data like AI traffic, lines, signs, change their position, but the building were in the original position.Then only problem i that i dont know hot to convert hexadecimal numbers to degree minutes seconds or hext to degrees, does anybody know the steps?Thanks.alfredo Mendiola LoyolaLima Peru
