EGTx? UK FIR codes?
Well, yes, T is one of those, but the rest are as geographically diverse as Perranporth (P), Fairoaks (F) and Oxford Kiddlington (K), rather putting in doubt that you can tell the area from the third letter. I was only pulling FFF's leg, though. He is mostly right.
TP, TF and TK were all built as Fighter command bases in the early years of the war. I wonder if T stood for airfields originally built for military use then handed over to the civvies. But then Biggin would be TB, not KB. Fascinating subject. Quite riveting. Thanks,
WorkingHard for starting the thread and bringing our attention to it.
Had to learn the ICAO codes when I did my time working in airline flight ops.
Oh, yeah so I see!
