Figure 2-11 Glideslope Indicator
The Glidepath Indicator is a vertical deviation scale for RNAV GPS approaches supporting SBAS vertical
guidance (LNAV+V, L/VNAV, LPV, LP+V). The Glidepath Indicator, a magenta diamond appears on the display
as soon as the Final Approach Fix (FAF) becomes the active waypoint, and GPS is the selected navigation
source. Full-scale deflection (two dots), is angular with upper and lower limits. The upper limit is ±492 feet
(150 meters) and lower limits depend on approach service level:
-
LNAV/VNAV, LNAV+V, LP+V is ±148 feet (45 meters)
-
LPV is ±49 feet (15 meters)
If the approach downgrades past the final approach fix (FAF), “NO GP” is displayed in place of the diamond.
NOTE:
The Glidepath Indicator appears on the display as soon as the Final Approach Fix (FAF) becomes the
active waypoint. Depending on procedure design, pilot action, and/or ATC clearance, the aircraft may be
centered on or above the glidepath when the Glidepath Indicator appears.
NOTE:
When the temperature is warmer than a standard day, the system-generated glidepath guidance for
a non-precision approach may cross below the FAF minimum altitude restriction.
