Graham Hi, Graham.
Not sure when - or perhaps if - Scottish FIR will be updated. My priority is Shannon FIR, and possibly some other similarly sized projects moving forwards.
Obviously, "Scottish Control" was a project that incorporated the old MACC sectors that went up to Prestwick in 2010 with the original Scottish sectors being merged in with them.
That did create duplication of those sectors (East, Isle of Man, North, Trent, Stafa, Wallasey and S29) between "London FIR" and "Scottish Control." For that reason, I decided not to further update "Scottish Control." It's not inconceivable that I might, at some point, split off those aforementioned sectors and simply have a Scottish FIR of sectors north of 55 North. However, it's not highly likely, if I'm honest.
Located as I am in the U.S., I don't have access to MATS part 2 data, and so any UK projects are going to be based solely on UK AIP data and observation of flight trackers. I think that's fine for projects like Shannon FIR, but less than satisfactory for UK projects.
So, for now, it's just going to be Shannon; hopefully, by the middle of next month, in an advanced Beta stage for people to use and provide feedback. One individual can only do so much when it come to testing, and I'm sure some issues will come to light from others using the add-on.
I'll post again when the Shannon FIR is ready.
