I am using FS2004. I downloaded
http://www.simviation.com/files/47jets/FSX-SP2_CitationX.zip created by Alejandro Rojas. I followed the steps to convert from FSX to FS2004 as instructed. I then downloaded
http://www.simviation.com/simviation/download.php?ID=2231 to help with the aircraft specs.
My problem is when I fly I am not getting a read out on my airspeed on the Glass or under the "shift+Z" panel. I do however get a read out on the GPS.
I have looked throught the Aircraft config file on the download and the Lear that came with FS2004 to see if their were any obvious differences. Couldn't find any.
Any help would be helpful.
