Glideslope Mode is available for LOC/ILS approaches
to capture and track the glideslope. Glideslope Mode is
armed when:
• A valid localizer frequency is tuned
• LOC Approach Mode is armed (the APR Key is
pressed and either LOC is the selected navigation
source or a LOC/ILS approach is loaded into the
flight plan; see LOC Approach Mode)

Once the localizer has been set as the navigation
source, the localizer and glideslope can be captured. Upon
reaching the glideslope, the flight director transitions to
Glideslope Mode and begins to intercept and track the
glideslope.
