Our guest today is Klaus Meier - the CTO of Skyguide. We talked about Virtual Centres and what is so special about them, what does location independence mean, what is the current state of play of the Virtual Centre in Switzerland, was the Covid-19 time a challenge or an opportunity for Skyguide, the role of Skyguide in the standardisation of Virtual Centres, lessons learned from the implementation process, how does Skyguide deal with recruiting new talents, closure of the Swiss airspace in June 2022 and, of course, our signature topic - what will the next 5 and 50 years bring into ATM.
