What a dogs breakfast UK GA has to endure!
I was refused using the GPS approach track at Shoreham recently in VMC, because no ATC controller available!!!
Then a GPS approach requiring an NDB to legally complete.
In other countries USA, Australia for example a GPS approach can be completed with their version of “Safetycom”
In IMC/IFR nearest ATC eg London, controls to radar MSA or IAP. Then transferred to A/G. Next approach not released by ATC until previous has landed.
Why do we have to reinvent the wheel?
