Thanks to everyone who helped out, including the supporting ATC in Finland ( @Miska Jokinen, @Daniel Edwards, @Julius Mannermaa) and neighbouring countries (EETT, ESOS) but also the pilots who made the checkout a real success. Having Tallinn Control online also helped a lot when it came to coordination of arriving aircraft.
I was quite delighted with the amount of traffic. During the two-hour checkout period there were over twenty movements. I think there was not a single silent minute on the frequency – not to exaggerate. What surprised me was that that there wasn’t a single text pilot even though there were a lot of movements. I, of course, occasionally had to type a few corrections, but nevertheless having the pilots on voice made the traffic flow a bit smoother and easier to manage.
From time to time it was quite hectic, for instance, to have a go-around aircraft and at the same time a couple of other aircraft flying not only in queues but also coming in from different directions at the same time.
I’m glad and relieved that there was more than enough traffic. My S2 checkout in comparison was deserted in terms of traffic and it had to be finished in Sweatbox. This one, on the other hand, was a real challenge and a great chance to practice my controlling skills which is something that I really appreciate!
Once again, thanks to @Jouka Ahponen for the mentoring me and @Joonatan Porkkala for hosting the checkout!
