Yes, full ATC required by CAA for GPS approach, hence hardly any in UK. With no change in sight from CAA Luddites not much hope of more at small airfields.
Even more crass, latest GPS approaches published ,still require an ancient NDB in the procedure!
There is now no legal requirement for ADF carriage in UK, so that, plus ADF unserviceable renders the approach far less useful.
Especially as in the real world, the ADF would be in the GPS database and not used at all.
