WARNINGS & CAUTIONS
WARNING:
Navigation and terrain separation must NOT be predicated upon the use of the terrain
function. The G1000 Terrain Proximity feature is NOT intended to be used as a primary reference for
terrain avoidance and does not relieve the pilot from the responsibility of being aware of surroundings
during flight. The Terrain Proximity feature is only to be used as an aid for terrain avoidance and is not
certified for use in applications requiring a certified terrain awareness system. Terrain data is obtained
from third party sources. Garmin is not able to independently verify the accuracy of the terrain data.
WARNING:
The displayed minimum safe altitudes (MSAs) are only advisory in nature and should not be
relied upon as the sole source of obstacle and terrain avoidance information. Always refer to current
aeronautical charts for appropriate minimum clearance altitudes.
WARNING:
The Garmin G1000, as installed in Beechcraft 58/G58 aircraft, has a very high degree of
functional integrity. However, the pilot must recognize that providing monitoring and/or self-test
capability for all conceivable system failures is not practical. Although unlikely, it may be possible for
erroneous operation to occur without a fault indication shown by the G1000. It is thus the responsibility
of the pilot to detect such an occurrence by means of cross-checking with all redundant or correlated
information available in the cockpit.
WARNING:
For safety reasons, G1000 operational procedures must be learned on the ground.
WARNING:
The altitude calculated by G1000 GPS receivers is geometric height above Mean Sea Level
and could vary significantly from the altitude displayed by pressure altimeters, such as the GDC 74A
Air Data Computer, or other altimeters in aircraft. GPS altitude should never be used for vertical
navigation. Always use pressure altitude displayed by the G1000 PFD or other pressure altimeters in
aircraft.
WARNING:
The Jeppesen database used in the G1000 system must be updated regularly in order to
ensure that its information remains current. Updates are released every 28 days. A database information
packet is included in the G1000 package. Pilots using an outdated database do so entirely at their own
risk.
Garmin G1000 Pilot’s Guide for Beechcraft 58/G58
190-00629-00 Rev. Bii
WARNINGS & CAUTIONS
WARNING:
The basemap (land and water data) must not be used for navigation, but rather only for nonnavigational situational awareness. Any basemap indication should be compared with other navigation
sources.
CAUTION:
The illustrations in this guide are only examples. Never use the G1000 to attempt to penetrate
a thunderstorm. Both the FAA Advisory Circular, Subject: Thunderstorms, and the Airman’s Information
Manual (AIM) recommend avoiding “by at least 20 miles any thunderstorm identified as severe or
giving an intense radar echo.”
CAUTION:
The United States government operates the Global Positioning System and is solely responsible
for its accuracy and maintenance. The GPS system is subject to changes which could affect the accuracy
and performance of all GPS equipment. Portions of the Garmin G1000 utilize GPS as a precision
electronic NAVigation AID (NAVAID). Therefore, as with all NAVAIDs, information presented by the
G1000 can be misused or misinterpreted and, therefore, become unsafe.
CAUTION:
To reduce the risk of unsafe operation, carefully review and understand all aspects of the
G1000 Pilot’s Guide documentation. Thoroughly practice basic operation prior to actual use. During
flight operations, carefully compare indications from the G1000 to all available navigation sources,
including the information from other NAVAIDs, visual sightings, charts, etc. For safety purposes, always
resolve any discrepancies before continuing navigation.
CAUTION:
CAUTION:
190-00629-00 Rev. B
The Garmin G1000 does not contain any user-serviceable parts. Repairs should only be made
by an authorized Garmin service center. Unauthorized repairs or modifications could void both the
warranty and the pilot’s authority to operate this device under FAA/FCC regulations.
The GDU 1040 PFD and MFD displays use a lens coated with a special anti-reflective coating
that is very sensitive to skin oils, waxes, and abrasive cleaners. CLEANERS CONTAINING AMMONIA
WILL HARM THE ANTI-REFLECTIVE COATING. It is very important to clean the lens using a clean, lintfree cloth and an eyeglass lens cleaner that is specified as safe for anti-reflective coatings.

1.1 INTRODUCTION
This System Overview Pilot’s Guide provides a basic
description of the G1000 System as it pertains to the
Beechcraft 58/G58. The description includes the Garmin
Automatic Flight Control System (AFCS).
System. A G1000 system block diagram is given in
Figure 1-1. Refer to the Pilot’s Guide Appendices for LRU
specifications.
1.2 SYSTEM DESCRIPTION
This section gives a brief description of the G1000
190-00629-00 Rev. BGarmin G1000 Pilot’s Guide for the Beechcraft 58/G58
Figure 1-1 G1000 System Block Diagram
1-1
SYSTEM OVERVIEW
• GDU 1040/GDU 1043 – The G1000 features two
displays, the GDU 1040 and GDU 1043. The GDU
1040 is a 10.4-inch LCD display with 1024 x 768
resolution and is configured as a Primary Flight
Display. The GDU 1040 displays the Flight Director
command bars, system annunciations and alerts,
pilot-selectable references, and flight information.
The GDU 1043 is configured as a Multi Function
Display which contains the dedicated AFCS keys
and GPS/Navigation controls. The displays communicate with each other through a high-speed data
bus (HSDB) Ethernet connection. Each display is
also paired via an ethernet connection.
• GMA 1347 – Installed between the MFD and PFD,
the GMA 1347 integrates NAV/COM digital audio,
intercom system and marker beacon controls. The
GMA 1347 communicates with both GIA 63s using
an RS-232 digital interface. The GMA 1347 also
controls manual display reversionary mode.
• GIA 63 – There are two GIA 63s. The GIA 63 func-
tions as a main communication hub, linking all LRUs
with the PFD and the MFD displays. Each GIA 63
contains a GPS receiver, VHF COM/NAV/GS receivers, and system integration microprocessors. Each
GIA 63 is paired with a respective display through
an ethernet connection. The GIAs are not paired
together and do not communicate with each other
directly.
Each GIA 63 also contains the AFCS software
which controls the Flight Director. During normal
operation, the GRS 77 AHRS and GDC 74A Air Data
Computer send attitude and air data information
to the GIA 63s. This information, combined with
GPS and other system data, is used by the Flight
Director and Autopilot. Flight Director commands
are calculated within the #1 GIA 63 and are sent to
the PFD for display and mode annunciation. Flight
information is also sent to the GSA 81 servos for
Autopilot operation. A GIA #1 failure results in the
loss of the AFCS system. Any GIA 63 failure results
in loss of the Autopilot function.
• GRS 77 – The GRS 77 is an Attitude and Heading
Reference System (AHRS) that provides aircraft
attitude and heading information to both the
G1000 displays and the GIA 63s. The unit contains
advanced sensors, accelerometers and rate sensors.
In addition, the GRS 77 interfaces with both the
GDC 74A Air Data Computer and the GMU 44
Magnetometer. The GRS 77 also utilizes GPS signals
sent from the GIA 63. Attitude and heading information is sent using an ARINC 429 digital interface
to both GDU 1040s and GIA 63s. AHRS modes of
operation are discussed later in this document.
• GMU 44 – The GMU 44 Magnetometer measures
local magnetic field information. Data is sent to
the GRS 77 AHRS for processing to determine aircraft magnetic heading. This unit receives power
directly from the GRS 77 and communicates with
the GRS 77 using an RS-485 digital interface.

190-00629-00 Rev. BGarmin G1000 Pilot’s Guide for the Beechcraft 58/G58
SYSTEM OVERVIEW
• GDC 74A – The GDC 74A Air Data Computer
processes information from the pitot/static system
as well as the outside air temperature (OAT) sensor.
The GDC 74A provides pressure altitude, airspeed,
vertical speed and OAT information to the G1000
system, and communicates with the GIA 63s,
GDU 1040s and GRS 77 using an ARINC 429 digital
interface.
• GEA 71 – The GEA 71 receives and processes signals
from the engine and airframe sensors. Sensor types
include engine temperature and pressure sensors as
well as fuel measurement and pressure sensors. The
GEA 71 communicates with both GIA 63s using an
RS-485 digital interface.
• GTX 33 – The GTX 33 is a solid-state, Mode-S
transponder that provides Modes A, C and S operation. The GTX 33 is controlled through the PFD
and communicates with both GIA 63s through an
RS-232 digital interface.
• SA 81 AFCS Servos – Four GSA 81 servos are
used for automatic control of the aircraft flight
control surfaces. One servo is used for the each of
the following:
Each servo moves its respective aircraft control
surface in response to commands generated by
internal servo calculations. For pitch trim, the servo
positions the aircraft pitch trim surface in response
to commands generated by automatic and manual
electric pitch trim calculations. Calculations are
performed using data sent through the common
serial data bus from the GIA 63. Manual Electric
Pitch Trim is also provided in response to the Manual
Electric Trim (
MET) switch.
1.3 OPTIONAL EQUIPMENT
This System Overview only covers the baseline
configuration of the G1000. Descriptions and procedures
relating to optional equipment is covered in the G1000

SYSTEM OVERVIEW
1.6 SYSTEM POWER-UP
The G1000 system is integrated with the aircraft
electrical system and receives power directly from electrical
busses. The Garmin G1000 PFD/MFD and supporting
sub-systems include both power-on and continuous builtin test features that exercise the processor, RAM, ROM,
external inputs and outputs to provide safe operation.
While the system begins to initialize, test annunciations
are displayed to the pilot at power-up, as shown in the
figure below. All system annunciations should be cleared
within one (1) minute of power-up. The GMA 1347 also
annunciates all bezel lights briefly upon power-up.
NOTE: Refer to the Beechcraft 58/G58 Pilot’s
Operating Handbook (POH) for specific procedures
concerning avionics power application and
emergency power supply operation.
On the PFD, the AHRS system displays the ‘AHRS
ALIGN: Keep Wings Level’ message and begins to initialize.
The AHRS should display valid attitude and heading fields
within one (1) minute of power-up. The AHRS can align
itself both while taxiing and during level flight.
NOTE: Refer to the Appendices for AHRS
initialization bank angle limitations.
NOTE: See the Annunciations and Alerts Section
for additional information regarding system
annunciations and alerts.

SYSTEM OVERVIEW
1.7 DISPLAY BACKLIGHTING
The G1000 PFD and MFD displays use photocell
technology to automatically adjust for ambient lighting
conditions. Photocell calibration curves are pre-configured
to optimize display appearance through a broad range
of cockpit lighting conditions. The PFD, MFD, and
GMA 1347 bezel/key lighting is typically controlled
directly by the existing instrument panel dimmer bus.
If desired, the PFD and MFD display backlighting can
be adjusted manually. The PFD, MFD and GMA 1347
bezel/key brightness can also be adjusted manually. The
GMA 1347 bezel/key brightness is directly tied to the
MFD bezel/key adjustment.
NOTE: Refer to the Primary Flight Display
section for instructions on adjusting backlighting
manually.
1.8 SYSTEM OPERATION
NORMAL MODE
The PFD and MFD are connected together on a single
Ethernet bus, allowing for high-speed communication
between the two units. Each GIA 63 is connected to a
single display This allows the units to share information,
thus enabling true system integration.
In normal operating mode, the PFD displays graphical
flight instrumentation instead of the traditional gyro
instruments. Attitude, heading, airspeed, altitude
and vertical speed are all shown on one display. The
MFD shows a full-color moving map with navigation
information. Both displays offer control for COM and NAV
frequency selection, as well as for the heading, course/baro
and altitude reference functions. On the left of the MFD
display, the Engine Indication System (EIS) cluster shows
engine and airframe instrumentation. Figure 1-5 gives an
example of the G1000 system in normal mode.

SYSTEM OVERVIEW
REVERSIONARY MODE
Should a failure occur in either display, the G1000
automatically enters reversionary mode. In reversionary
mode, all important flight information is shown on the
remaining display. An example of reversionary mode
entry due to a failed PFD is shown in Figure 1-6.
If a display fails, the GIA 63-GDU 1040 Ethernet
interface is cut off. Thus, the GIA can no longer
communicate with the remaining display, and the NAV
and COM functions provided to the failed display by the
GIA are flagged as invalid on the remaining display. The
system reverts to using backup paths for the GRS 77, GDC
74A, GEA 71 and GTX 33, as required. The change to
backup paths is completely automated for all LRUs, and
no pilot action is required.
NOTE: The system alerts the pilot when backup
paths are utilized by the LRUs. Refer to the
Annunciations and Alerts Pilot’s Guide for further
information regarding these and other system
alerts.
Reversionary mode may also be manually activated by
the pilot if the system fails to detect a display problem.
Reversionary mode is activated manually by pressing
the red DISPLAY BACKUP button at the bottom of
the GMA 1347 Audio Panel. Pressing this button again
deactivates reversionary mode.
AFCS PREFLIGHT TEST
When power is applied to the G1000, the AFCS system
starts preflight system tests. ‘PFT’ is annunciated on the
PFD at the AFCS System Status field. The Autopilot
disconnect aural alert tone sounds at the end of the test
and the ‘PFT’ annunciation disappears.

Figure 1-6 Reversionary Mode
190-00629-00 Rev. BGarmin G1000 Pilot’s Guide for the Beechcraft 58/G58
SYSTEM OVERVIEW
AHRS OPERATION
In addition to using internal sensors, the GRS 77
AHRS uses GPS information, magnetic field data and
air data to assist in attitude/heading calculations. In
normal (primary) mode, the AHRS relies upon GPS and
magnetic field measurements. If either of these external
measurements is unavailable or invalid, the AHRS uses air
data information for attitude determination. Four AHRS
modes of operation are available (see table below) and
depend upon the combination of available sensor inputs.
Loss of air data, GPS, or magnetometer sensor inputs is
communicated to the pilot by message advisory alerts.
GPS Input Failure
The G1000 system provides two sources of GPS
information. If a single GPS receiver fails, or if the
information provided from one of the GPS receivers is
unreliable, the AHRS seamlessly transitions to using the
other GPS receiver. An alert message informs the pilot of
the use of the backup GPS path. If both GPS inputs fail,
the AHRS continues to operate in reversionary ‘No GPS’
mode so long as the air data and magnetometer inputs are
available and valid.
Air Data Input Failure
A failure of the air data input has no effect on AHRS
output while AHRS is operating in normal/primary mode.
A failure of the air data input while the AHRS is operating
in reversionary ‘No GPS’ mode results in invalid attitude
and heading information on the PFD (as indicated by red
‘X’ flags).
Magnetometer Failure
If the magnetometer input fails, the AHRS transitions
to one of the reversionary ‘No Magnetometer’ modes and
continues to output valid attitude information. However,
the heading output on the PFD does become invalid (as
indicated by a red ‘X’).
NOTE: Please refer to the Annunciations and
Alerts Pilot’s Guide for specific AHRS alert
information.
NOTE: Pilots should be aware that aggressive
maneuvering in any of the three reversionary
mod es li sted below can degrade A HRS
accuracy.

2.1 INTRODUCTION
WARNING: In the event that the airspeed, attitude,
altitude, or heading indications become unusable,
please refer to the backup instruments.
This section describes the major features of the G1000
Primary Flight Display (PFD) as installed on Beechcraft 58/
G58 aircraft. Information is displayed using the G1000’s
two 10.4-inch color flat-panel displays. During normal
operation, the left display is configured as a Primary Flight
Display.
The PFD provides increased situational awareness by
replacing the traditional instrument “six pack” on the
pilot’s panel with an easy-to-scan display that provides
a large horizon and airspeed, attitude, altitude, vertical
speed, navigation, communication, annunciation,
terrain, traffic, and lightning (optional) information. The
PFD also controls the operation of the transponder, the
selection of NAV/COM frequencies, audio volume, and
many navigation features. The operation of these features
is explained in other supporting sections.
The G1000 system controls were designed so that,
regardless of which seat the pilot is flying from, the aircraft
can be flown with one hand and the controls manipulated
with the other hand.
The PFD displays the following:
• Flight Instruments (2.4)
– Airspeed Indicator with True Airspeed Box
– Attitude and Slip/Skid Indicators
– Altimeter with Selected Altitude and Barometric
