Vertical Glideslope intermittent

[tcbc8222]

I was flying the RNAV (GPS) RWY 23 into Anderson Regional (AND) on Sunday afternoon and my vertical glideslope would disappear and come back intermittently. I maintained my configuration and continued to descend.
Has anyone had this issue? Is it my equipment or the Airports?

Thanks,

Since an RNAV GPS approach is not dependent on any ground based equipment, it certainly wasn't the airport's issue.

You don't state what GPS navigator was driving the VNAV (or HNAV), but the problem could be in one of three places - the GPS navigator, the Skyview connection to the navigator, or a GPS intermittent outage that has nothing to do with the equipment in your plane. You may want to check your wiring and GPS antenna connectivity as well.
