SECTION 1 – INTRODUCTION
The G1000 controls and keys have been designed to
simplify operations and minimize workload and time to
access sophisticated functionality. The following provides
an overview of the primary function(s) for each key and
control.
• (1) NAV VOL / ID Control – Controls the NAV
audio level. Press to toggle the ident filter ON and
OFF. Volume increase and decrease is shown in the
field as a percentage.
• (2) NAV Frequency Toggle Key – Swaps the
standby NAV frequency and the active NAV fre-
quency when pressed (the standby NAV frequency
is white whereas the active NAV frequency is green).
Note that NAV frequencies are shown as active only
when the HSI is set to either NAV1 or NAV2.
• (3) NAV Frequency Selector – The concentric
knobs tune the MHz (large) and kHz (small) standby
frequencies for the NAV receiver. Press on the small
knob to toggle the tuning cursor (cyan box) between
the NAV1 and NAV2 fields.
• (4) Heading Selector – Manually selects a heading.
When this knob is pressed, a window displaying a
digital heading momentarily appears to the left of the
Heading Indicator and the heading bug synchronizes
with the compass lubber line.
• (5) Joystick – Changes the map scale when rotated.
When pressed, it activates the map pointer.
• (6) CRS/BARO Selector – The large knob sets the
altimeter barometric pressure and the small knob
adjusts course. Course is adjustable when the HSI is
in NAV 1 & 2 or OBS/SUSP modes only). Pressing
the small knob centers the CDI on the currently
selected VOR.
• (7) COM Frequency Selector – The concentric
knobs tune the MHz (large) and kHz (small) standby
frequencies for the COM receiver. Pressing the
small knob toggles the tuning cursor (cyan box)
between the COM 1 and COM 2 fields.
• (8) COM Frequency Toggle Key – Swaps the
standby COM frequency and the active COM fre-
quency. Pressing and holding this key for ten sec-
onds automatically makes the 121.5 MHz emergency
frequency the active frequency.
• (9) COM VOL/SQ Control – Controls the COM
audio level. Pressing this knob turns the COM auto-
matic squelch ON and OFF. Audio volume increase
and decrease is shown in the field as a percentage.
• (10) DIRECT-TO Key ( ) – Allows the user to
enter a destination waypoint and establish a direct
course to the selected destination (specified by
identifier, chosen from the active route, or taken
from the map cursor position).
• (11) FPL Key – Displays the active Flight Plan
Page for creating and editing the active flight plan
or accessing stored flight plans.
• (12) CLR Key (Default) – Erases information or
cancels an entry. To immediately display the Naviga-
tion Map Page, press and hold CLR (MFD only).
• (13) FMS Knobs – The concentric knobs are
used to select the page to be viewed (only on the
MFD)— the large FMS knob selects a page group
(MAP, WPT, AUX, NRST) while the small FMS
knob selects a specific page within the page group.
Pressing the small FMS knob turns the on-screen
cursor ON and OFF. When the cursor is on, data
may be entered in the different windows using a
combination of the small and large FMS knobs.
The large FMS knob is used to move the cursor on
the page. The small FMS knob is used to select
individual characters for the highlighted cursor loca-
tion. When the G1000 displays a list of information
that is too long for the display screen, a scroll bar
appears along the right side of the display. The scroll
bar graphically indicates the number of additional
items available within the selected category.
