Crossing ATZ above 2000ft - need to call in?
I don't fly as much in the UK these days, so I'm a bit rusty on the regs. But here's what happened the day before yesterday I was flying from Lydd to Denham and had radar service from Farnborough. As you get squeezed between LCY and Stansted's airspace, you kind of have to go over Stapleford. I was at 2300ft.
Farnborough: "G-XXXX, Do you want to call Stapleford and then get back to me after the crossing?"
Me: "Do I have to?"
Farnborough: "If you're routing through, then yes. But if you avoid it you don't, of course".
I though I was clear as the ATZ only goes to 2000ft AAL, no? Why did she ask me to call in - she had my height info as she just beforehand had called out traffic to me. Anyway, I tracked around it. No huge thing, but I'm just curious if I've missed something pertinent.
