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 while navigating by GPS, the system automatically
NOTE:
switches to LOC as 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.
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 active
frequency field. The frequency that was previously in the NAV1 active frequency field is transferred to
standby.
• If the current CDI navigation source is GPS, and if the approach frequency is already loaded into the NAV1
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.
