Deviation Indicator (VSI and VDI)
The Glidepath Indicator is a vertical deviation scale for GPS approach service levels supporting SBAS vertical
guidance (LNAV+V, L/VNAV, LPV, LP+V) or advisory vertical guidance (LNAV+V, LP+V, Visual). The Glidepath
Indicator, a magenta diamond (Figure 2-13) 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 limit depends on
approach service level as follows:
• LNAV/VNAV, LNAV+V, LP+V, Visual is +/- 148 feet (45 meters).
• LPV is +/- 49 feet (15 meters).
A hollow gray diamond represents a preview of the glidepath indicator. This is shown while inbound to the
FAF waypoint, but before the FAF waypoint is the next active waypoint. The preview is also shown when the
AFCS is coupled to the Vertical Path Tracking Mode (VPTH) while inbound to the FAF waypoint, until the
AFCS captures the glidepath; refer to the AFCS section for more information about Vertical Path Tracking Mode.
The hollow gray preview diamond changes to a solid magenta diamond to indicate the glidepath indicator is
active.
If the approach downgrades past the final approach fix (FAF), "NO GP" is displayed in place of the diamond.
