Hi, I'm having trouble getting the fmc in the 800/900 series to accept the airport codes while trying to install flight plans,I get the message NOT IN DATABASE,this is something new what do I need to do to rectify this.regards aga:-)

Aga,What flight plan are you trying to enter? Care to post the complete plan here?What AIRAC cycle do you have installed? Check the folder %FSroot%FMCWPNAVDATA and make sure you have at least the six files listed in the below picture. (You might or might not have the BACKUP folder depending if you have updated your AIRAC data or not)http://forums.avsim.net/user_files/181753.jpgHope it helps,
