Why after passing the FAWP a GPS approach is allowed to operate for 5 minutes if there is a satellite problem? Why would the GPS receiver not immediately alert the pilot that there is satellite problem?
In other words, the GPS receiver may indicate all is normal but in actuality there is a satellite problem. If I am flying a GPS approach, I want to know immediately if there is a satellite problem. Excerpt from AIM below.
******If a RAIM failure occurs after the FAWP, the receiver is allowed to continue operating without an annunciation for up to 5 minutes to allow completion of the approach (see receiver operating manual). If the RAIM flag/status annunciation appears after the FAWP, the missed approach should be executed immediately.**********
