Does RNAV use glideslope?
Does RNAV use glideslope? On the other hand, due to some technical differences that are immaterial to pilots, most RNAV (GPS) approaches with WAAS have an electronic glideslope and are referred to as APV (approaches with vertical guidance). For practical purposes, APV approaches are flown similarly to an ILS.
Do pilots use ILS approach?
The Instrument Landing System (ILS) is a radio navigation system that provides precision guidance to aircraft approaching a runway. ILS approaches allow most general aviation pilots to land in as little as 1/2 statute mile visibility and as low as 200-foot cloud ceilings.
