So, what's the plan when the enroute or destination diversion has no precision or non precision approaches other than those certified GNSS/PBN 0.3? Because it costs a fortune to maintain that ground infrastructure to support and its cheaper/easier to Do GNSS certification once with no follow up maintainable, backup or future calibration required of ground based navaids?
Or are we going to continue with STS/STATE? This is not just the UKs problem, its a global mil issue that extends into assurance of civilian use of classified airspace.
