One interesting change at EHRD as a result of the removal of navaids is that RNAV1 is now required even for the ILS. Which means, for example, that someone with a BK KLN unit would not be able to fly the ILS. This feels like the bigger story in many ways.
Is this current, for EHRD?
It doesn’t say RNAV1 is mandatory. That would be outrageous because the only way you could legally fly the ILS, with a GPS failure, would be by declaring a mayday.
Is the INS the primary system and DMEs are correcting it?
Yes.
Then why have an INS at all, when you have two DMEs ?
Over remote areas with no DMEs, mountains, etc. Look at the IAPs into say Innsbruck

No that’s the old one. You can’t fly the old one anymore without GPS because the beacons are gone. Here are the new variants for RWY 24:
Both show RNAV 1 required, and you can see the fixes are now all GPS waypoints instead of using traditional navaids. I just went and flew the new approaches yesterday to get familiar.
So no radar vectors at Rotterdam? Most ILS traffic around the “modern” world is vectored.
The “problem” is the missed approach, which also is to some RNAV waypoint. There is no radar vectoring below the MVA.
Note 3 on the EHRD chart says clearly that there is vectoring

Of course we get vectors, but I suppose the missed approach is the real issue:
Looks like it’s not just EHRD either. EHAM, EHEH, and EHLE all no longer have a non-RNAV 1 approach. And even then there’s often an ILS in only one direction, with RNP clearly giving more options.
Re RNAV1, the KLN94 contains all the waypoints, so nobody would know. And yes you can jump on me for that too because it never had the FAA PRNAV LoA

Like flying a “DME required” ILS with no DME I guess…
