Thanks guys. Yes, LXE can export the required .lxa file that the 7007 will read for the airports database. The problem is to produce the .lxa file, you need to have an airport database to point the LXE software to.


David,

I had prepared this answer for you after your last post so please forgive duplication of some of the points you already know.

The last US airports data base available from LX is the Jeppesen 2009 edition. You can use the program Lxe on a PC to construct a user airports data base. The user airports file is a text file but the LX7007proIGC V2.01 manual page 89 states airport data base format is .LXA. There does not seem to be a direct way to construct an airport database in the .LXA format. To construct an up to date airport database in .LXA format using the program Lxe, you first need to construct a User Airport file in comma delimited text format and convert that text file to .LXA format during the save dialog presented by FileExportAirportsLX7007.

There are two simple ways to construct the airports text file:
1. Create a text file from the turnpoints in the Turnpoints tab, right clickSave AsTPfilenameSaveAs typeComma separated file (*.txt)
2. Import a Cambridge .dat file into the User Data base file (lower list) in the Airports tab. Right clickImportCambridge .dat file. Next, Right clickExport to save the file to disk.

You are now ready to convert the saved text file to .LXA format during the save dialog presented by FileExportAirportsLX7007.

Before converting to .LXA format you will need to edit the text file to strip out waypoints that are not airports. It is simplest to do this exercise in Lxe or in a text editor. You can do the edit in a spreadsheet but you may find some strange characters turning up in the data.

There may be a simpler way of doing this exercise but this is the only one I know. Also useful to know is Lxe does not perform properly on operating systems after XP.
