Steve6443 and what's the response from DFS?
Or is it 'ok'?
Not getting at anyone, but usually those responsible from the US are happy to talk about their requirements and how we can all make sure those requirements are fulfilled while causing the least possible disruption. Not sure why it would be different in Germany. I've always found them pretty understanding once the impact of their initial request has been explained.
Not that I've been involved this time.
