Brett, it works the same way for FS2002 and FS2004.

Look in the plane's aircraft.cfg file for entries starting with ui_

These are the menu entries. Edit them as you like, just be sure you
don't create any duplicate entries.

Hope this helps,

Is there a way in FS 2002 to sort aircraft added on or perhaps to edit
the aircraft files themselves to allow them to customize how they're
sorted? I have numerous planes - tac fighters, strategic bombers,
airliners, prototypes - what have you, but FS 2002 doesn't sort them
well. I'd like to group them by actual type (fighter, bomber, etc)
also by manufacturer (real world - Northrop, Republic) rather than by
developer. Any suggestions?
