Compiler is failing as the active runway definition in https://github.com/VATSIM-UK/UK-Sector-File/blob/main/Airports/EGYM/Active_Runway.txt now refers to a non-existant runway.

Actually it's one in UK.rwy that causes the compiler to fail - Active_Runway.txt has been removed in a different PR.

Update UK.rwy please

Along with updating UK.rwy, the coordinates for the runway are wrong, see page 87 of the AMDT.

Note MIL Charts show THR Coords in a different format, so it's usually better to look in the AD 2.12 section of the textual data (in this case on page 80 of the AMDT) to get the more precise DD MM SS.SS value.

And in general, if you do find an error, it's best to propose the change directly on that line of the file so it can be checked and committed in one click rather than someone having to do it and it be checked again. (i.e. "The coordinates are wrong" isn't as helpful as "Suggest changing this number 2 to a number 3" or whatever it is.)
