Airport Morning

Another potential entry to UFR's sfbm challenge.  February 2017 Challenge - S.F.B.MFebruary 2017 Challenge - S.F.B.M
Hello all. Here is February's challenge for you. I was all set to do something else when I discovered the formula in question wasn't working any more. A formula update last year seems to have "broken" it. I've notified the author so maybe I can introduce you to it another time.
So this month's challenge is a bit of a rush job. A couple of people have requested something along these lines, using S.F.B.M colouring, so it seemed like a good one to be getting on with. I know it's been done before as a challenge elsewhere but it's not one I've tried myself and I hope it will be new to a few of you too. S.F.B.M  is such an important colouring that many of us use every day but I think we could all learn a lot more about it through a challenge like this. Yes?
So... what do you need to do? The idea of this challenge is to focus on the combination of a Pixel formula with one of the S.F.B.M. colourings. Most of your layers shou Title is subject to change but if I do change it it will probably still have something to do with airports.

One again in the spirit of the challenge I have made the ufr file available for download:
