Depends.
Have you flown that approach before in the same aircraft with no problems?
.Did the warning clear by either by itself of after you recycled it or anointed it with Holy Water?
Check RAIM etc.
What are your other options?
Do you have lots of fuel?
Is your alternate Wx good. Is it close or hours away?
If needs be and the equipment is now working you could try a second approach unless SOP says no. Momentary glitches happen
However is it really necessary.
Be prepared to abort, recover to a sensible altitude and go somewhere else.
Avoid target fixation….do you really want or need to visit the thriving community of Little Moose Poop?
