As a former aircraft guy, I'll take this- Squadron has the tarmac http://www.squadron.com/ItemDetails.asp?item=VE1634
As for the road signs, I am not sure. I know Archer has Arabic Wall Slogans. Maybe you can convert them. http://www.archertransfers.com/MIDEASTAFV.html
You might get away with it unless a judge speaks arabic!
