3.3 NAV OPERATION

FREQUENCY RANGE

TheNAVradiosreceiveintheVOR/ILSfrequencyrange of 108.00 to 117.95 MHz with 50 kHz spacing. The NAV Frequency window displays the following information:

•NAV1 and NAV2 active and standby frequencies

•NAV1 and NAV2 identifier indication (if the Morse code identifier is received by the system)

•Color-coded indication of the selected NAV radio

•Morse code identifier status

MORSE CODE IDENTIFIER

Press the VOL/PUSH ID knob to turn the Morse code identifier ON and OFF. When the identifier is ON, a white ID indication appears to the left of the active NAV frequency, and the Morse code is heard on the NAV audio. The VOR/LOC Morse code identifier is displayed next to the active NAV frequency.

WhentheidentifierisOFF,theIDindicationdisappears and the Morse code is off.

NAV audio is available with the ID filtered out for listening to HIWAS and FSS transmissions on VOR stations.

The desired NAV radio is selected for navigation by pressing the CDI softkey located on the PFD. The three navigation modes that can be selected are:

•VOR1 (or LOC1) – If NAV1 is selected, a single green arrow (shown) labeled either ‘VOR1’ or ‘LOC1’isdisplayedontheHSIandtheactiveNAV1 frequency is displayed in green.

•VOR2 (or LOC2) – If NAV2 is selected, a double green arrow (not shown) labeled either ‘VOR2’ or ‘LOC2’isdisplayedontheHSIandtheactiveNAV2 frequency is displayed in green.

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

NOTE: In GPS mode, both active NAV frequencies are displayed in white.

The NAV radio is selected by the CDI softkey.

NAV2 radio is selected on the audio panel. The Morse code identifier for the GHM VOR can be heard.

ADF/DME TUNING

The optional BendixKing KR-87 ADF is not tuned by the G1000 system. Refer to the Honeywell BendixKing KR 87 ADF Operators manual for ADF information. ADF volume is also adjusted through the KR 87.

TheG1000systemtunestheoptionalDMEtransceiver. The UHF DME frequency is paired with a VHF NAV frequency, providing DME distance information. Frequency pairing is automatic and only the VHF NAV frequency is shown on the display.

DME TUNING

The DME radio is tuned by selecting the associated NAV system or HOLD in the DME Tuning window. The DME Tuning window is located to the right of the HSI on the lower right corner of the PFD. Pressing the top-level DME softkey toggles the DME Tuning window ON and OFF.

NOTE: When another Auxiliary window is turned on,the DMETuning window is replaced on the PFD.

Selecting DME Transceiver Pairing

The following DME transceiver pairing can be selected:

•NAV1–TunestheDMEfrequencyfromtheselected NAV1 frequency.

•NAV2–TunestheDMEfrequencyfromtheselected NAV2 frequency.

•HOLD – When in the HOLD position, the DME frequency remains tuned to the last selected NAV frequency.

NOTE: When turning ON the G1000 for use, the system remembers the last frequency used for DMETuning and the NAV1, NAV2 or HOLD state prior to shutdown.

To select DME transceiver tuning:

1.Turn the small FMS knob to select the desired DME tuning.

2.Press the ENT key to complete the selection.

NOTE: Pressing the CLR key while in the process of DME tuning cancels the data entry and reverts back to the previously selected DME tuning state.

NOTE: Pressing the FMS knob activates/ deactivates the cursor in the DME Tuning window.
