NAV RADIO SELECTION AND ACTIVATION

The NAV Frequency Box is composed of four fields; two standby fields and two active fields.  The active 

frequencies are on the right side and the standby frequencies are on the left.

A NAV radio is selected for navigation by selecting the 

CDI

 Softkey located on the PFD.  The active NAV 

frequency selected for navigation is displayed in green.  Selecting the 

CDI

 Softkey once selects NAV1 as the 

navigation radio.  Selecting the 

CDI

 Softkey twice selects NAV2 as the navigation radio.  Selecting the 

CDI

Softkey a third time activates GPS mode.  Selecting the 

CDI

 Softkey again cycles back to NAV1.

While cycling through the 

CDI

 Softkey selections, the NAV Tuning Box and the Frequency Transfer Arrow are 

placed in the active NAV Frequency Field and the active NAV frequency color changes to green.

The three navigation modes that can be cycled through are:

• VOR1 (or LOC1) – If NAV1 is selected, a green single line arrow (not shown) labeled either ‘VOR1’ or ‘LOC1’ 

is displayed on the HSI and the active NAV1 frequency is displayed in green.

• VOR2 (or LOC2)  – If NAV2 is selected, a green double line arrow (shown) labeled either ‘VOR2’ or ‘LOC2’ 

is displayed on the HSI and the active NAV2 frequency is displayed in green.

• GPS – If GPS Mode is selected, a magenta single line arrow (not shown) appears on the HSI and neither NAV 

radio is selected.  Both active NAV frequencies are then displayed in white.
