OPERATION – COM

4.2 COM OPERATION

FREQUENCY SPACING

The G1000 COM radios can tune either 25 kHz spacing (118.000 to 136.975 MHz) or 8.33 kHz spacing (118.000 to 136.990 MHz) for 760-channel or 3040-channel configuration.
COM channel spacing is configured through the MFD on the System Setup Page of the AUX Page group.

AUTOMATIC SQUELCH

Automatic squelch quiets unwanted static noise when no audio signal is received, while still providing reasonable sensitivity to weak COM signals. To disable auto squelch, press the VOL/PUSH SQ knob.
When automatic squelch is disabled, COM audio reception is always on. Continuous static noise is heard over the speaker and phones, and an appears on the display.

SELECTING A COM RADIO

The desired COM radio is selected by pressing the COM MIC keys on the audio panel. When the COM MIC key is annunciated, the associated active COM frequency is displayed in green in the COM Frequency window.

4.3 NAV OPERATION

FREQUENCY RANGE

The G1000 NAV radios receive in the VOR/ILS frequency range 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.

NAV RADIO SELECTION FOR NAVIGATION

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’ is displayed on the HSI and the active NAV1 frequency is displayed in green.
VOR2 (or LOC2) – If NAV2 is selected, a double green arrow (not 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 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.
When the identifier is OFF, the
ID indication disappears
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.
NAV2 radio is selected on the audio panel. The Morse code identifier for the GHM VOR can be heard.

DME TUNING

The G1000 system tunes the optional DME transceiver. 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 WINDOW

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 DME Tuning window is replaced on the PFD.

Selecting DME Transceiver Pairing

The following DME transceiver pairing can be
selected:
NAV1 – Tunes the DME frequency from the selected NAV1 frequency.
NAV2 – Tunes the DME frequency from the selected 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 DME Tuning and the state prior to shutdown.

4.4 FREQUENCY AUTO-TUNING

The G1000 system offers multiple auto-tuning capabilities. The PFD allows auto-tuning of COM frequencies associated with the nearest airports. The MFD provides auto-tuning of both COM and NAV frequencies from waypoint and nearest pages. In addition, the primary NAV frequency is entered automatically in the NAV window during approach loading or approach activation.
Frequencies can be automatically loaded into the frequency windows in the following ways:
• By using the ENT key when the frequency is highlighted on the appropriate page (PFD and MFD).
• When loading or activating an approach (PFD and MFD).
NOTE: Turn the FMS knob to scroll through a list of frequencies.

AUTO-TUNING ON THE PFD

COM frequencies for the nearest airports may be viewed and automatically loaded from the Nearest Airports Window on the PFD.
