Pushing these buttons no longer displays the items on the ND. Everything else in terms of waypoints still seems to work, including putting in waypoints in the FMC and so on. This both on the NG & 744.I think this may have occurred after my 0609 install of the AIRAC data from the Navigraph site, but that is just a guess.I tried to reinstall the previous 0608 version, but nothing changed, in fact the IDENT page still continues to Aug31Sep27/06 as the active date!Where are the PMDG Airacs stored? I have backups, and could overwrite them, but can't seem to find them.* Orest

Go to FMCWP - Navdata and delete the content, then reinstall cycle 0608 (rev. 2). It worked for me. There are missing information in the demo Airac 0609, as reported several times on the forum (check the navdata forum).Regards.
