I was flying in and around Mount Shasta (Northern California) north of Redding and received message on the 430W that I lost GPS signal. I was at 11,500 on north side of a 14,000 mountain. It came back about 5-10 minutes later as I was southbound.
I was enroute from Redding area for Lake Tahoe and doing a practice VFR GPS 18 approach into South Lake Tahoe. Between the IAF and the FAF about 8500 ft I lost the signal again. It came back just before the missed approach point.
During this time I had foreflight on an IPAD and never lost position on the map. I also had a 696 and it showed me on the moving map but I lost the approach course on the 696 that the 430 sends to it.
Question 1: Do you think this was an antennae issue or a GPS loss of signal in the area? Did it not have enough antennas in sight for the 430, but enough to run the ipad/696?
Question 2: I was in VMC. What the heck would you do in IMC during a "real approach". Lets say I did not have the IPAD or 696. The missed approach is a GPS waypoint, how would you navigate to it. What if you could not get ATC for a vector due to mountains. I realize I was over the lake and could have done a 180 and climbed over the lake...but that is not the published route. I also realize this would be an emergency and do what I needed to do to, but what is the recommended course of action?
Never had this happen before. Flown behind a few 430's.
