I read the WOAI forum. Region Avia has issue problem without afcad airports in Russia. I found two airports has no afcad in your FS2004 only. I'm not responsible for FSX.
1. Omsukchan - UHMF - new afcad.
2. Kostomuksha - ULPM - new afcad. But the WOAI one of airport.txt is error elevation should read 664' not 0'. I saw scenery was sink hole. I correct elevation level is 664 feet.
Please update your airport.txt should be:
ULPM,N64* 37.07',E30* 41.20',664
Hope your satisfy with flight plans and scenery. Place your files into mircosoft game\flight simulator 9\addon scenery paste it there.
