Had an issue at Zurich just before. Flown VFR around the mountain area with VFR approval from Approach. Eventually turned back to land at Zurich. I noticed that on final switching from Approach to Tower that my messages were not recieved.
I kept getting an On Guard warning but had notifies that I was on final…
So to the controller… Sorry!
Anyone got any ideas what causes it??
TIA - IF MIKE
