Just make sure you get out of the way when the 757 announces on the common frequency he is turning base to final.
There might be no controller in a tower but the approach itself is still controlled by ATC. If you're IFR that may well lead to delays in or out if there's more than one aircraft in the system... I assume you're also talking to ATC if you're flying practice instrument approaches under VFR?
So porco, you didn't answer my question. If everything within 30 miles of LHR is squawking mode S, will you need such a large surface area??
Probably didn't answer because I've got no idea. I'll hand that one over to any airspace planners or DAP reps that might be here. I am just a humble and much maligned UK atco
There are airspace classification changes afoot though, so who knows what the future may hold.
