Displays –
• selected ILS/GLS identifier or frequency, approach front course
• ILS/GLS DME distance
• navigation source annunciation.
The navigation source annunciation on the third line is completely independent of
the approach data on the first two lines. It identifies the source of navigation
performance for the deviation scales. Possible combinations for source
annunciation are:
ILS/GLS approach reference data appears when an appropriate approach has been
selected to the active route and –
• manually tuned or
• auto-tuned and the airplane is
• < 150 NM from the destination airport or
• < 50 NM from Top of Descent or
• FMC is in descent mode
If the tuned ILS/GLS frequencies disagree, the frequency turns amber with an
amber horizontal line through it.
If the approach courses in the ILS/GLS receivers disagree, the course turns amber
with an amber horizontal line through it.
Indicates the navigation path relative to the airplane position.
The pointer indicates the localizer relative to the airplane position and is:
• unfilled white diamond for LOC if NPS are shown
• unfilled magenta diamond for LOC if NPS are not shown
• in view when the localizer signal is received
• filled magenta diamond when within 2 1/2 dots from the center.
