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 GPS Mode, the system switches to NAV Mode 

as the final approach course is intercepted (within 15 nm of the FAF).  See the GPS Navigation 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.
