There are a few additional hurdles to overcome from the Airports' perspective
What, like having to employ 3 approach rated ATCOs at £70,000 each, plus employer's NIC, and having to spend a few tens of k for the approach design?
It's a great step forward on the landscape of regulatory politics, but in terms of increased GA utility there is a long way to go. Any navaid-based approach can be flown right now using the GPS overlay "for monitoring
" and these overlays have been in the IFR databases for years.
As HWD says,
non-ATC approaches are desperately needed.
