4.3 NAV OPERATION
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 pressing the
CDI
Softkey located on the PFD. The active NAV
frequency selected for navigation is displayed in green. Pressing the
CDI
Softkey once selects NAV1 as the
navigation radio. Pressing the
CDI
Softkey a second time selects NAV2 as the navigation radio. Pressing the
CDI
Softkey a third time activates GPS mode. Pressing 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 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 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 appears on the HSI and neither NAV radio is
selected. Both active NAV frequencies are then displayed in white.
