I think Beauvais is actually off the bottom of my current map. I was just using that image to figure out how it all worked. Merville would be nice to have early though, if possible.

CW - I will try out the ,-2 multiplier. That should give a big enough area to cover any airfield.
----- Having tried it I see that only -2 works so maximum size is 3200x3200m, big enough for any airfield.
