Number of GPSes for downgrade to occur during GPS approach
Asked by: connor 2009 views Instrument Rating
Hi everyone,
I went through the old post http://www.askacfi.com/10753/lpv-or-lnavvnav.htm
and came up with questions that I want to clarify.
- How many satellites make the approach mode to downgrade?(For example, LPV to LNAV)
- There are total 3 WAAS satellites available over North America, do we need all 3 of them?
