Hi Grumpy,
To add aircraft to the available planes ina campaign you need to edit whats known as the TechTree in any given campaign file.
If you navigate to the campaign folder inside CFS3 or any of the various Addon games such as MAW, ETO you will see .xml files with names like:
fortress europa.xml (stock CFS3)
Attack in the west.xml (ETO)
If you open up one of these files using notepad and scroll down about half way you will see the section relating to the techtree. below is the techtree from the stock CFS3 campaign file fortress europa.xml.
you can see the various aircraft types listed, to add more just copy one section of the file and then put in teh model name of the plane you want to use, and put in teh date you wish to see the plane become available for use.

</TechTree>
you can find the model names by looking for the M3D files found inside each of the various aircraft folders.
example ETO_Hur_Mk2.M3D is the model file for the ETO Hurricane MkII, simply write in the name like this,
<Aircraft Type="ETO_Hur_Mk2">
<Date Month="1" Year="1941"/>
</Aircraft>
then copy your new entry into the techtree.
open up a couple of the ETO or MAW campaign files and you will soon see how the structure works.
hope this helps,
regards Rob.
