This document is intended as a very basic guide, and is complemented by the details given in Tim Quine's PDF document "Flags in PlanePlotter" which can be found in the Plane Plotter Yahoo group Files area.
From: http://groups.yahoo.com/group/planeplotter/files/flags/
Or: http://www.homepages.mcb.net/bones/SBS/Utilities/Kinetic_Utilities4_Bitmaps.htm
For example: C:\Tools\COAA\PlanePlotter\Flags\
The file should be downloaded to your main Plane Plotter directory: C:\Tools\COAA\PlanePlotter\Flags\
This file will contain lines such as:
004000 0043FF C:\Program Files\COAA\PlanePlotter\BMPFlags\Zimbabwe.bmp 006000 006FFF C:\Program Files\COAA\PlanePlotter\BMPFlags\Mozambique.bmp
However, if you have downloaded the flags.txt file the directory entries will most likely be wrong. Open the file with Notepad, and use the Edit, Replace... function (Ctrl-H). Using the example above:
Find what: C:\Program Files\COAA\PlanePlotter\BMPFlags\
Replace with: C:\Tools\COAA\PlanePlotter\Flags\
Click: Replace All
In Plane Plotter: Options, Flags, Define. Navigate to the flags.txt you just edited.
In Plane Plotter, open the Aircraft View (View, Aircraft list, or click on the aircraft toolbar button), and your flags should be displayed. You can alter the field order with the View, Aircraft data window, Setup data window layout dialog.
