AUTO-TUNING NAV FREqUENCIES ON APPROACH ACTIVATION
note:
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 FMS Mode, the system switches to NAV Mode as
the fi nal 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 fi eld as follows:
• If the current CDI navigation source is FMS, the approach frequency is transferred to the NAV1 active
frequency fi eld. The frequency that was previously in the NAV1 active frequency fi eld is transferred to
standby.
• If the current CDI navigation source is FMS, and if the approach frequency is already loaded into the NAV1
standby frequency fi eld, 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 fi elds of the selected CDI NAV radio.
MArker beAcon receiver
note:
The marker beacon indicators operate independently of marker beacon audio and cannot be turned
off.
The marker beacon receiver is used as part of the ILS. The marker beacon receiver is always on and detects
any marker beacon signals within the reception range of the aircraft. The receiver detects the three marker tones
– outer, middle, and inner – and provides the marker beacon annunciations located to the left of the Altimeter
on the PFD.
