An excellent video.
Particularly interesting for me, as this morning I received a "no further action will be taken" email from the CAA following an airspace infringement of Edinburgh Airspace.
I was on Scottish Information from Inverness to Cumbernauld. I returned to Scottish immediately I cleared the Cumbernauld circuit, routing south to Fishburn, and was distracted setting the squawk. Edinburgh had to call Scottish to inform me.
Perhaps someone with knowledge could suggest the best procedure. I saw how easier phoning the flight details made the ATC workload.
I made it to Turweston with no more trouble.
After PPRing Cumbernauld, booking out at Inverness, PPRing Fishburn and Turweston, I never thought of phoning any ATC unit
