Exactly....
We used the #2 system as backup to confirm flightpath, but my experience was in the procedure validation and checks.
You confirm, as I suspected, that it was used in practice.
I concur, with all of the issues with the procedure variables allowed, that this is an accident waiting to happen, but not for lining up on the 28R taxiway at night with 28L closed......that is even out there for all of the potential conflict issues.
