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?

A Raim Warning you should still have GPS and can execute the missed. I
have had a complete failure of the GPS just past the FAF and in the
soup. Approach had just told me to go to advisory. My action was to
level off, hit the switch back to approach, advise them of the situation
and request a vector, a the while holding the final approach course. I
knew I would be safe for a period of time on that course.

ATC then told me I could descend 300 more feet, the ATIS had reported
the ceiling should be 300 feet below me so I took a chance and broke out
with the center line of the runway straight ahead of me and could make a
normal landing.
