Just as controllers should be required to sit in the sim and run a practice QRH on an electrical fire to get an idea of what we are up against
Would love to! I think you'll find most controllers would be interested. Sort it, and we'll turn up.
On the other hand, pilots have ALWAYS been welcome to visit us, and we're constantly reminding you all on here. But when was the last time I saw an ATPL holder visit the centre? Never, that's when.
PS We get 15 hours flying training (used to be more) and many hours of lectures (and part of several exams) on aircraft characteristics, physics of flight etc. How much does a CPL holder have to learn about ATC?
