Question for the enroute controllers. You have a spamcan or two, not filed
/G, cleared direct to some fix. You don't care whether they are navigating
with pilotage, a VFR GPS, or a ham sandwich, so long as they are on radar
and don't go too grotesquely out of the way.

Now the radar goes kaplooey, or whatever noise radar makes when it decides
not to be radar any more.

How do you get these guys into the no-radar rules - point them at the
nearest navaid? Tell them to join the nearest airway?


Bingo.



How do you maintain
separation?


You might not. But if they weren't on the verge of collision immediately
prior to the loss of radar they won't be on the verge of collision
immediately after the loss of radar. While there must be separation
standards avoiding collision is the reason for ATC.



Does this possibility make you nervous while the radar is
working?


Nope. The loss of radar will not cause the ATC facility to hit an aircraft
or terrain.
