To open an airport’s air traffic file click the
‘Open’ button on the lower left corner of the
editor window. The ‘Close’ button will end
editing of the opened file while keeping the
editor open. ‘Save’ does exactly what it says
– saves the air traffic file being edited.
‘Exit’ shuts down the editor.
