ENR NDBs are gone and buried but the little 50 Watt ones (locators) are still in widespread use on/near airfields. Still useful IMO but will probably go within the next decade or so I suspect. Or such is the plan.
VORs are getting phased out as spares for the old Racal Mk IIs that NATS have all over the place are long extinct and so keeping them running is becoming increasingly difficult, hence the move to decommission a large number of them (in order to free up spares), those will probably go over the next decade too however. IIRC the grand plan is to, over the next decade, move to GPS/DME Nav.
Interesting times, but I await with interest to see what effect these tecnological developments will have on private GA. Mode S anyone?
