NOTE: During the final segment of an ILS or WAAS GPS approach, the path-
ways boxes automatically adjust to correspond with the localizer/glideslope
(ILS) or horizontal/vertical (GPS) deviation signals received from the external
navigator.
When an approach providing vertical guidance is activated, Pathways are shown
level at the selected altitude. Pathways are shown level at the selected altitude up to
the point along the final approach course where the altitude intercepts the extended
vertical descent path or glideslope. From the vertical path descent or glideslope
intercept point, the pathways are shown inbound to the Missed Approach Point (MAP)
along the published lateral and vertical descent path.
During an ILS approach, the initial approach segment is displayed in magenta at
the segment altitudes if GPS is selected as the navigation source on the CDI. When
switching to the localizer inbound with LOC selected as the navigation source on the
CDI, pathways are displayed in green along the localizer and glideslope.
If GPS is the selected navigation source on the HSI, the pathways boxes are magenta.
If LOC is the selected navigation source on the HSI, the pathways boxes are green for
the ILS. Pathways boxes are not displayed for segments such as heading legs or VOR
radials.
