You're supposed to go missed if you have a RAIM or GPS failure message.
But all the GPS IAP's I've seen have missed approaches that require use of
the GPS to fly correctly (fly to this waypoint, then go to this other
waypoint and hold). So what do you do? Use the GPS to fly the missed
despite the RAIM failure (assuming the whole GPS hasn't gone belly up)?
Call ATC for help?


This isn't peculiar to GPS approaches. What do you do on a VOR approach
when the VOR fails and it's needed for the missed approach procedure?
