AUTO-TUNING NAV FREQUENCIES ON APPROACH ACTIVATION
The primary NAV frequency is auto-tuned upon loading a VOR or ILS/Localizer approach.
NOTE:
When an ILS/LOC approach has been activated in GPS Mode, the system switches to NAV Mode as
NOTE:
the final approach course is intercepted (within 15 nm of the FAF). See the Flight Management Section for
details.
NAV frequencies are automatically loaded into the NAV Frequency Box on approach activation, on both PFD1
and PFD2.
When loading or activating a VOR or ILS/LOC approach, the approach frequency is automatically transferred
to a NAV frequency field as follows:
• If the current CDI navigation source is GPS, the approach frequency is transferred to the NAV1 or NAV2
active frequency fields. The frequency that was previously in the NAV1 or NAV2 active frequency fields are
transferred to standby.
• If the current CDI navigation source is GPS, and if the approach frequency is already loaded into the NAV1
or NAV2 standby frequency field, the standby frequency is transferred to active.
• If the current CDI navigation source is NAV1 or NAV2, the approach frequency is transferred to the standby
frequency fields of the selected CDI NAV radio.
