You need to use ACT Tools

Download from here (The link is inoperative)

Readme file is in English. You will need to get this translated.

You need to make two batch files like these:

extract.bat

@echo off
java -jar Act.jar extract actors.static

and

create.bat

@echo off
java -Xmx1024M -jar Act.jar create
pause

Running extract.bat will produce new files

outbuildings.txt
outchiefs.txt
outchiefsroad.txt
outnstationary.txt
outwing.txt

if you rename these to

inbuildings.txt
inchiefs.txt
inchiefsroad.txt
innstationary.txt
inwing.txt

then run create.bat a new MWactors.static is created

If you want a small actors.static so that you can work in FMB MapEditor mode make a backup of inbuildings.txt then delete all the entries and run create.bat

A small MWactors.static is created. Put this in your map folder.
Now you can open the map but the buildings will be missing.

Make your new airfields and save new mapfiles

Use extract.bat to open the new actors.static

Merge the new outbuildings.txt with the backup file.

Run create.bat to make a new actors.static with the new airfield now merged with the old buildings.

Hope this helps.
