1.5 TUNING BOX

On both the PFD and the MFD, a cyan tuning box ap­pears over the standby frequency fi eld and can be moved
from one standby frequency fi eld to another for the pur­pose of tuning or radio selection.

In both the COM and NAV windows, the frequency
toggle arrow appears next to the tuning box, between the
active and standby frequencies.

A Frequency Toggle Arrow appears between the two

NOTE: If the frequency tuning box is on a
selected COM sub-window when a signal
is received or transmitted for this radio, the
Frequency Toggle Arrow is replaced by an
RX or a TX indication, respectively.

NOTE: When the desired frequency is entered in
the tuning box, it becomes a standby frequency.
Pressing the Frequency Toggle key places this
standby frequency into the active fi eld, and vice
versa.

• RX – When a signal is received on a COM radio,
a white RX indication appears to the right of the
corresponding COM frequency for the duration of
the signal reception.

• TX – When a microphone is keyed, a white TX
indication appears to the right of the correspond­ing COM frequency for the duration of the signal
transmission.

• ID – When the VOL/PUSH ID knob is pressed, a
white ID indication appears to the left of the NAV
frequency on the selected NAV sub-window and
the Morse code identifi er audio for the selected
VOR frequency can be heard if the corresponding
NAV radio is selected on the audio panel.

Window

3.1 OVERVIEW

The G1000 NAV radios operate in the aviation fre­quency band of 108.00 to 117.95 MHz, with 50 kHz
channel spacing.

The Navigation Frequency window is located to the
left of the Navigation Status bar, provides the control and
display of dual VOR/ILS receivers ( NAV1 and NAV2) and
displays the following information:

• NAV1 and NAV2 active and standby frequencies

• NAV1 or NAV2 identifi er indication (if the active

NAV frequency is a valid frequency and its Morse
code identifi er signal is received by the system).

• Color code indication of the selected NAV receiver

• Indication of the Morse code identifi er fi lter status

3.2 VOLUME

Volume level for the NAV radios can be adjusted by
using the VOL/PUSH ID knob (top knob on the left
side of the display) located above the NAV Frequency
Toggle key. Turning the VOL/PUSH ID knob clockwise
increases volume level, while turning this knob counter­clockwise decreases volume level.

Preliminary

3.3 MORSE CODE IDENTIFIER

Pressing the VOL/PUSH ID knob toggles the Morse
code identifi er fi lter ON and OFF for the active NAV fre­quency next to which the tuning box is located. When
the Morse code identifi er fi lter is ON, an ID indication
appears to the left of the corresponding active NAV fre­quency.

The Morse code identifi er for an active NAV frequency
can only be heard if the Morse code identifi er fi lter for
the corresponding NAV radio is turned on (i.e., if the ID
indication appears next to the active NAV frequency) and
if the corresponding NAV radio is selected on the GMA
1347 audio panel (i.e., the associated NAV radio annun­ciator lights are illuminated).

Here, since NAV2 is the only

NAV radio selected on the
audio panel, only the Morse

The desired NAV radio can be selected using the CDI
softkey. The three navigation modes that can be selected
with the CDI softkey are as follows:

• NAV1 – If NAV1 is selected as the NAV radio, a
single green arrow is displayed on the HSI and
the active NAV1 frequency is displayed in green.

• NAV2 – If NAV2 is selected as the NAV radio, a
double green arrow is displayed on the HSI and
the active NAV2 frequency is displayed in green.

• GPS Mode – If GPS mode is selected, a single
magenta arrow appears on the HSI and none of
the active NAV frequencies are selected.

4.1 OVERVIEW

The G1000 system offers multiple auto-tuning capa­bilities that help to reduce cockpit workload. The PFD
allows for the auto-tuning of COM frequencies associated

pages. In addition, regardless of the display, the pertinent
primary NAV frequency is entered systematically in the
NAV window upon approach loading or activation.

In brief, frequencies can be automatically loaded in
their respective frequency windows in the following
ways:

• By using the ENT key when the frequency is
highlighted on the appropriate page ( PFD and
MFD).

• By using the LD NAV1 and LD NAV2 softkeys
when on the appropriate page ( MFD only).

• Upon loading or activating an approach ( PFD and
