I cannot see any problems.
I can't comment on FW
newt,but co-location certainly wouldn't work for rotary.
Not only is it the (pretty much) exclusive use of LFA9, it's the "Fields & Clearings" of which scores are used in DHFS training. Helo pilots who can only land at airfields aren't much use, and MoD doesn't own many fields, holes in woods,or sides of hills! Many of the local natives are friendly, and (in exchange for a peppercorn rent and an annual "lunch") allow the irreplaceable use of their land.
