Since there was a tropical system overhead us yesterday and the weather really sucked I went to the hangar to do some minor cleaning. While listening to the tower I heard a Saratoga on the RNAV to Rwy 13 get cleared to land. A short while later the Saratoga told the tower the GPS had lost satellite signal (RAIM) and they had to execute the missed approach. They went around in the clouds and returned to Jacksonville approach.
Right then a Citation came on frequency also on the RNAV Rwy 13 approach and was also cleared to land. Right after being cleared the Citation told the tower the GPS had lost satellite signal and they had to execute the missed approach. The tower told him the aircraft before them had gotten the same indication and had also executed the missed approach. I heard them go around in the clouds and they also returned to Jacksonville approach.
A few minutes later the Saratoga came back on frequency but this time "VFR" below the clouds (clouds were now about 1,000ft) and they landed on RWY 13. Once on the ground the Citation came back on tower frequency but he was executing the ILS approach to RWY 31. They landed on RWY 31 with maybe a 5kt tailwind.
This is the 1st time I had heard this actually happen (GPS unuseable for landing in bad Wx) with one of the airplanes having to use the old fashion ILS to land. Now I am REALLY glad I still have ILS capability in my airplane and don't rely exclusively on the GPS "Magenta line".
This is the Saratoga track on FlightAware.
This is the Citation track on FlightAware.
Moral of the story... unless it is a life and death emergency situation, DON'T DO RNAV APPROACHES WITH A NON CERTIFIED GPS!
