1. INTRODUCTION
1.1
Content, Scope, Purpose
This document provides Instructions for Continued Airworthiness (ICA) for the NXi configuration
of the Garmin G1000 Integrated Flight Deck including the GFC700 Automatic Flight Control
System (AFCS) as installed in the Textron Aviation G36 and G58 aircraft, under STC
SA01830WI. This document satisfies the requirements for continued airworthiness as defined
by 14 CFR Part 23.1529 and 14 CFR Part 23 Appendix G. Information in this document is
required to maintain the continued airworthiness of the G1000 and GFC700.
Throughout this document, the GFC 700 autopilot system is included in the G1000NXi system
description and is identified separately only when needed.
This manual covers both the G36 Bonanza and G58 Baron. All references in the manual cover
both aircraft unless specifically noted.
This document is a supplement to the existing G36 or G58 Aircraft Maintenance Manual, the
G1000 58/G58 System Maintenance Manual (Garmin p/n 190-00451-03), and the G1000
System Maintenance Manual for the G36 for STC SA1595WI-D (Garmin p/n 190-01259-00) or
the G1000 System Maintenance Manual for the G58 for STC SA01584WI-D (Garmin p/n 19001180-02). Except where noted, refer to the applicable Aircraft Maintenance Manual or the
applicable System Maintenance Manual for servicing instructions.
Applicability
This document applies to all Textron Aviation G36/G58 aircraft equipped with the G1000NXi
system. All G1000NXi G36/G58 airplanes are configured per General Arrangement drawing
005-00620-41 Rev 1 or subsequent.
Modification of an aircraft by this Supplemental Type Certificate (STC) obligates the aircraft
operator to include the maintenance information provided by this document in the operator’s
Aircraft Maintenance Manual.
Identifying an STC Configuration
The General Arrangement drawing lists the G1000 System Software Version numbers approved

The installation of these units supports Electronic Stability Protection (ESP) and Under Speed
Protection (USP) features. ESP works to assist the pilot in maintaining the aircraft in a stable
flight condition. When autopilot is not engaged, ESP helps avoid inadvertent flight attitudes and
provide airspeed protection while the pilot is hand-flying the aircraft. The USP feature will
correct for slow airspeeds while the autopilot is engaged. USP will lower the nose of the aircraft
to maintain an airspeed that prevents the aircraft from stalling.

3. Software and Configuration
3.1
Configuration Mode Overview
Throughout this document, references are made to the PFD and/or MFD being in configuration
mode. The configuration mode exists to provide the avionics technician with a means of
configuring, checking, and calibrating various G1000 sub-systems. Troubleshooting and
diagnostics information can also be viewed in this mode.
To start the G1000 system in configuration mode, follow these steps:
1. Apply power to the G1000 system by applying aircraft EXT power, selecting the L BAT
MASTER, R BAT MASTER, and AVIONICS MASTER switches to ON.
2. Pull the MFD and PFD circuit breakers.
3. Press and hold the ENT key on the MFD while applying power using the MFD circuit
breaker.
4. Release the ENT key after ‘INITIALIZING SYSTEM’ appears in the upper left corner of
the MFD.
5. Press and hold the ENT key on the PFD while applying power using the PFD circuit
breaker.
6. Release the ENT key after ‘INITIALIZING SYSTEM’ appears in the upper left corner of
the PFD.
CAUTION:
Configuration Mode contains certain pages and settings that are critical to aircraft
operation and safety. These pages are protected and cannot be modified, unless
the technician is properly authorized and equipped. However, most protected
pages are viewable to allow system awareness for troubleshooting.
NOTES
If the specific procedure requires an SD card to be in the top slot of the PFD/MFD,
this card must be inserted prior to applying power to the PFD/MFD. Any time a
card is inserted, the power to the PFD/MFD must be cycled.
For a complete description and breakdown of each Configuration Mode page, refer
to the G1000 System Maintenance Manual listed in Table 1-2.
SET>ACTV Configuration
Throughout the configuration mode pages, there are SET and ACTIVE columns for input/output
settings and other parameters.
SET:
Refers to a setting or group of settings that reside in PFD Internal Memory and/or the
Master Configuration Module.
ACTIVE: Refers to an ‘active’ setting or parameter currently being used by the LRU. LRUs
store the ‘active’ settings within internal memory.
Data can be manually copied from one column to the other (and consequently from PFD
memory to the LRU memory and vice-versa) by using the following two softkeys, when
available:

SET>ACTV (read ‘Set to Active’) softkey: Allows the installer to send the information in
the SET column (data stored in the master config module) to the ACTV column (data
used by LRU).
G1000 Supplemental Maintenance Manual
Textron Aviation G36/G58
190-02128-05
Page 3-1
Revision 3

ACTV>SET (read ‘Active to Set’) softkey: Causes the LRUs current settings to be copied
to the master configuration module as SET items.
CAUTION:
The ACTV>SET softkey must be used with caution! If an improperly
configured unit is installed, this softkey causes the wrong configuration to
replace the correct aircraft configuration.
In the first example shown in Figure 3-1 the SET columns do not match the ACTIVE
columns. The inequality between SET and ACTIVE indicates a configuration mismatch.
By pressing the SET>ACTV softkey, this copies the SET column to the LRU unit’s
configuration memory. The settings then become the ACTIVE settings for the LRU being
configured.
Figure 3-1, SET>ACTV Diagram
When troubleshooting the system, technicians can look for inequalities between SET and
ACTIVE columns. Certain problems can be resolved simply by pressing the SET>ACTV
softkey, which reloads settings to the specific LRU from the PFD. (Note that this can also be
accomplished by reloading the configuration files for the LRU. Section 7 describes this process
for each LRU).

When configuration settings are changed, the technician receives on-screen prompts and/or
confirmations such as those shown in Figure 3-3.
Figure 3-3, Configuration Status
Data Transmission Indicators
Several configuration screens utilize an indicator light system to show discrete (ON/OFF) data
and/or hardware component status. Unless otherwise noted, the following applies to all such
status indicators:

Green Checkmark: Expected data is successfully received and is ON. A green check
could also indicate that the parameter/component is working correctly.

Red X: Expected data is not received. A red X could also indicate that a
parameter/component is invalid.

White N/A: Expected data is OFF, or no data is expected.

Software Files
Software files are defined by part number and version number on the General Arrangement
drawing. Each G1000 system LRU reports the software version it currently contains to the user
in two places.

Normal System Mode: The Aux – System Status page lists each LRU and the
reported software version.

Configuration Mode: The System Status page (System page group) reports more
detailed LRU information, including software version, part number, and LRU status.
Software files are loaded to LRUs from the PFD System Upload page in configuration mode.
Configuration File Descriptions
There are configuration files for baseline settings and various options. Configuration files
contain preset selections for input/output channels, aircraft-specific settings, and LRU-specific
settings.
IMPORTANT!
Certain software and configuration files are REQUIRED to be re-loaded
during maintenance that involves removal and replacement of G1000
equipment.
Refer to Section 7 for re-configuration requirements for each individual
G1000 LRU. Pay special attention to the selection of option files for the units
to assure a complete load.

Configuration File Storage
The storage of G1000 system configuration files is unchanged from that depicted in the
applicable Maintenance Manual, except as noted in Figure 3-5 for the GRS 79 and the GDC 72.
The GDC 72 ADC air data configuration file is loaded directly to GDC 72 internal memory. A
copy of the file is stored in the GDC 72 configuration module. The GRS 79 stores AHRS
calibration data acquired during the post installation checkout, which is characteristic to the
specific installation. A copy of this calibration data is stored in the GRS configuration module.
While performing maintenance on this unit, re-calibration may be required. See Section 7.11 for
more information on re-calibration criteria.

G1000 Hardware/Software Compatibility Check
Before installing software, the technician must first ensure that hardware part numbers are
compatible with the G1000 system software image that is to be used. The General
Arrangement drawing shows all available combinations of hardware and software part numbers.
A G1000 system loader card is required to install software and configuration settings to a newly
installed G1000 system. The part number of the software image used to create the loader card
is directly associated with the combination of software file part numbers and version levels that
are defined on the General Arrangement drawing. Should software part numbers or versions
change, a new software image part number is issued.
IMPORTANT
After verifying hardware/loader card compatibility, record the software image
part number and all LRU hardware part numbers in the appropriate aircraft
records before proceeding.
NOTE
Throughout the next section of this document, screen shots and examples are
used to illustrate the software and configuration loading process. These
screen shots are provided as reference only. Always refer to the General
Arrangement drawing for the correct software file names, versions and part
numbers.
3.4
Equipment Verification (Third Party/Optional Equipment Documentation)
It is extremely important to know exactly what equipment the aircraft is equipped with before
loading any files. Loading the incorrect files could lead to longer down time and unplanned
removal of equipment.

Garmin optional equipment (i.e. GDC 74 ADC, GRS 77 AHRS, GRS 79 AHRS, or GDC
72 ADC, GTX 33 or GTX 3X5R, GSR 56, etc.). Section 3.4.1 helps find which units are
installed without a physical inspection.

Third party avionics equipment interfaced to G1000 (DME, non-Garmin traffic systems,
WX-500, etc.). To determine if the third party equipment is installed, check the circuit

breaker panel for circuit breakers for the units, and check for G1000 controls for the third
party devices.
Determining Installed Garmin Units
Use the table in Appendix A to determine what the unit part number is based on the unit’s serial
number reported on the MFD Aux - System Status page in Normal mode or PFD System Status
page in Config mode. The table lists the units that have different loader card option files so the
installer can choose the correct file without requiring the unit to be physically inspected.

Revision 3
Test Equipment
A milliohm meter and Kelvin probes are recommended for this test. However, an alternate
method may be used to provide equivalent results by using the following procedure and a
standard voltmeter, power supply with adjustable current limit, and ammeter. The test set up for
this alternate method is described below.
All test equipment used for the bond checks must be calibrated.
1. Connect the positive lead of the power supply to airframe ground. Connect/touch the
positive lead of the voltmeter to the same point.
NOTE
Ensure that the voltmeter and power supply probes do not touch, so as not to
induce contact resistance.
2. Touch negative lead of power supply to each of the test points listed while performing
Step 3. At each required point, configure the power supply to produce 1 amp before
measuring voltage. (Use an ammeter to ensure current is within minimum of 1 amp
±100 milliamp at each point). Do not allow the reference current to exceed 1.5 amps for
safety.
3. With the current set to 1A, the voltage reading will be the value of the bonding
resistance. Set the voltmeter to measure millivolts and null the reading. Measure the
voltage from airframe ground (step 1) to each required test points and record the
voltage. (Perform Step 2 at each required point and ensure that minimum of 1 amp
±100 milliamp is present when measuring the voltage.)
TIP: When a 1A current is used all the millivolt readings are the same as milliohms, and
required no further calculation of bond resistance. If 1 amp reference current cannot be
maintained and is higher divide the measured voltage by current to get the resistance
value. Alternatively, calculate the percentage increase in current and then reduce the
measured voltage reading by the same percentage. Example: If the measured current is
1.2 amps, (20% high from the desired 1 amp current) and the measured voltage is 3.0
millivolts, then the value recorded will be 3 millivolts reduced by 20% which is 2.4
millivolts which is the same as 2.4 milliohms.

GRS 79 Earth Magnetic Field Updates
The GRS 79, utilizes an Earth magnetic field model which is updated once every five years.
The update is expected to be available from Garmin every five years as long as the GRS 79
remains a Garmin-supported product.
The G1000 system alerts the operator that the magnetic field database is out of date by issuing
the message “AHRS SERVICE – AHRS Magnetic-field model needs update”. Garmin will
distribute updates as part of the navigation database cycle. If the IGRF model in the update is
newer than the model installed, a prompt will appear for the GRS (Select “OK” to update the
IGRF Magnetic Field Model). Use the FM Knob and ENT key to select “OK”.

Fixture Torque Check Procedure
This test is an alternative to the automated torque check procedure.
The GSM 86 servo gearbox does not have an adjustable slip clutch; however, the torque value
can be measured using this procedure.
IMPORTANT!
This adjustment requires the use of the Garmin fixture, P/N T10-00110-01. For detailed
operating instructions for the fixture, refer to GSA8X / GSM85(A) Installation Manual.
It is highly recommended that the following test be performed at
temperatures between 50° F and 120° F.
1. Remove the GSM 86 servo gearbox as per Section 6.13.
2. Place the GSM 86 servo gearbox on the adjustment fixture and secure with the toggle
clamps. Install the fixture cable between the capstan under test and the fixture capstan.
Remove the slack in the cable using the tension adjustment knob. Tighten the two
wingnuts on bottom of fixture while holding the top thumbscrews.
3. Attach a socket to a calibrated torque wrench of appropriate range and place on top of
the fixture capstan. Adjust the wrench support fixture so that it contacts the handle in
the appropriate location.
4. Connect a 2 Amp, 24 V, DC power supply to the fixture.
5. Place the solenoid switch to "on" and move the direction switch to the clockwise or
counter-clockwise position. Allow the spring clutch to rotate at least one revolution in
each direction (note: the capstan itself is fixed.)
6. Observe the torque reading for at least two full revolutions in each direction. Ensure the
minimum and maximum torque readings are within the tolerance specified.
7. If the minimum and maximum torque values are within the specified range in Table 4-3,
the GSM 86 spring cartridge is acceptable. Reinstall the GSM 86 servo gearbox per
Section 6.13.
8. If the minimum and maximum torque values are not within the specified range in Table
4-3, the GSM 86 slip clutch cartridge must be replaced.

5. TROUBLESHOOTING
This section provides instructions and guidance for G1000 system troubleshooting as installed
in the Textron Aviation G36/G58 aircraft.
IMPORTANT!
Sections 6, 7 and 9 provide detailed instructions on equipment removal,
replacement, configuration, and return-to-service testing. Anytime a G1000
component or LRU is removed, swapped, or replaced, the technician must
follow the procedures given in Sections 6, 7 and 9 to ensure proper operation
of the system.
Troubleshoot the G1000 system by first identifying, then isolating the specific failure to the
responsible LRU. There are several indications that the G1000 presents to the pilot or
technician, showing overall system condition. A course of action should be determined based
on the information presented on the display. This section shows possible scenarios likely to be
encountered during normal operation and gives troubleshooting guidance to the technician to
resolve problems.
Figure 5-1, Aux – System Status Page
G1000 Supplemental Maintenance Manual
Textron Aviation G36/G58
190-02128-05
Page 5-1
Revision 3
The Aux – System Status page displays the following information for each LRU and subfunction:

Status: A green check is displayed for properly operating LRUs. A red ‘x’ appears when
an internal LRU fault is detected and it has taken itself offline, or if the MFD cannot
communicate with the LRU.

Serial Number: Each LRU serial number is displayed (functions such as COM and GS
are contained within an LRU; therefore, serial numbers are not shown for these).

Current SW Version Loaded.
When troubleshooting, first check to ensure that each LRU status is ‘green’ and that the correct
software is loaded in each unit. Additional airframe and database information is also displayed
on this page.
5.1
System Annunciations
If data fields become invalid due to an LRU failure, the PFD/MFD typically annunciates the
failure with a large red X, as shown in Figure 5-2.

Revision 3
Failed Path Messages
The following message indicates there is a data path connected to the GDU (PFD or MFD) or
the GIA (1 or 2) that has failed.
FAILED PATH – A data path has failed.
The FAILED PATH message is triggered by a timeout of any one digital channel.
IMPORTANT!
Once the FAILED PATH message has been triggered, it will remain on the list
of messages until the next power cycle. This latching was implemented so
that for intermittent failures, the message would remain at the end of the
flight (to alert maintenance crew). Also, this keeps the crew from having to
acknowledge message repeatedly in the case of intermittent failures.
To determine which path is causing the FAILED PATH message, start the PFD and MFD in
configuration mode. Using the FMS knobs, scroll to the pages listed below.
The channels that are checked are listed on these pages in config mode:
1) GDU RS-232 / ARINC 429 CONFIG (PFD and MFD)
2) GIA RS-232 / ARINC 429 CONFIG (GIA1 and GIA2)
3) GIA CAN / RS-485 CONFIGURATION (GIA1 and GIA2)
The box next to each channel indicates the current status of the channel per the below:

Red X = data path is known to be failed

Amber question mark (?) = data path status is unknown

Green checkmark ()= data path is known to be good
The applicable data paths can be verified by viewing the following configuration mode pages.
NOTE
For paths not listed here, refer to the applicable G1000 Line/System Maintenance
Manuals listed in Section 1.1.

Backup Communications Path Checks
Overview
The G1000 system architecture is designed with redundant communication ports for several
LRUs so that critical information can continue to be displayed in the event of an equipment or
wiring failure. Of most importance is flight attitude, heading, and air data information. The GRS
79 and GDC 72 (if installed) have separate ARINC 429 data lines which are all capable of
sending data to the displays. The GTX 335R or GTX 345R (if installed) have two redundant
serial communication paths for the same purpose. See the Applicable Line/System
Maintenance Manuals (refer to Section 1.1) for a basic G1000 block diagram depicting general
system architecture. The GRS 79 and GDC 72 replace references to the GRS 77 and GDC 74
in that manual, and the GTX 335R or GTX 345R replace references to the GTX 33 in that
manual. Several other diagrams are shown later in this section for illustrative purposes. When
troubleshooting, refer to the G1000 Wiring Diagram listed in Table 1-1.
NOTE
Refer to Section 9.8 for procedures on checking the status of each configured
G1000 / GFC 700 backup data path.

moment the PFD first displays the blinking TEST COMPLETE? Message.
7. The operator should carry out the actions called for in the prepared test sequence.
NOTE
It is important that all actions are carried out in the order and at the precise
elapsed time as specified in the prepared test sequence.
8. When the operator has completed the actions specified in the test sequence, press the
ENTER button to indicate that the process is complete. When this is done, the TEST
COMPLETE field stops blinking.
9. The PFD informs the operator if the installation has passed or failed the magnetometer
interference test. If the test passes, no further action is required for this test.
If the test fails, the installation should be considered unreliable until the source of
magnetic interference is identified and remedied. When the magnetometer interference
test fails, record the three magnetometer maximum deviation values and their
corresponding timestamps. Reference the installation manual for the GRS 79 (19001852-00) for acceptable magnetic interference limits. Compare the corresponding
timestamps with the prepared test sequence to identify which action produced the
problem. Contact Garmin for assistance in resolving the problem.
NOTE
Two common reasons for a failed magnetometer interference test are: 1)
new equipment is installed in close proximity to the GMU 44 magnetometer,
and 2) an existing or new electronic device has become grounded through
the aircraft structure instead of via the proper ground wire in a twisted
shielded pair.
10. Press the ENT key on the PFD to conclude this procedure.

GIA Test
GPS Signal Acquisition
Figure 7-2, Aux – GPS Status Page (MFD)
The GIA units should normally acquire a GPS navigation solution within 5 to 10 minutes of
startup, provided the aircraft is outside (or indoors with a GPS repeater). Select the Aux – GPS
Status page on the MFD. Two softkeys on the bottom of the display allow the user to toggle
between GPS 1 and GPS 2. Verify that both receivers show 3D DIFF NAV on the MFD.
NOTE
It may be necessary to temporarily disable or move away from GPS repeaters
while testing, as repeaters may adversely affect GPS receiver performance.
VHF COM Interference Test
This test must be conducted outside. Use of a GPS repeater inside a hangar may result in a
failed test. This procedure assumes that the system is currently set to 25 kHz COM channel
spacing. Once the signal acquisition test has been completed successfully, perform the
following steps:
1. On the MFD, monitor GPS signal strength bars on the Aux – GPS Status page.
2. On the PFD, ensure that the CDI is set to GPS. If it is not, press the ‘CDI’ softkey until
GPS ENR is displayed.
3. Verify that the GPS “INTEG” flag is out of view.
4. Select 121.150 MHz on the No. 1 COM transceiver.
5. Transmit for a period of 35 seconds while monitoring GPS 1 signal strength levels.
6. During the transmit period, verify that the GPS “INTEG” flag does not come into view on
the PFD and verify that GPS 1 does not lose a 3-D navigation solution on the MFD.

Revision 3
Compass Rose Evaluation of Magnetic Disturbances for Magnetometer
Calibration Procedure (Optional)
NOTE
The Magnetometer Calibration Procedure that follows in Section 7.11.3
(Calibration Procedure B) must be carried out at a site that is
determined to be free of magnetic disturbances. If it is unsure whether
the site is ‘clean’, the technician should verify that the site is ‘clean’ by
following the guidance provided in Section 7.11.2. The technician may
skip Section 7.11.2 if the site condition is acceptable.
Typically, a compass rose is an acceptable location to perform the
magnetometer calibration procedure. However, because not all
compass roses are well maintained, even an existing compass rose
should be regularly evaluated using the method described here to
determine if it is free of magnetic disturbances. If evaluation of an
existing compass rose indicates that magnetic disturbances are
present, then an alternative location must be found to perform the
Magnetometer Calibration Procedure.
A G1000-equipped airplane that has completed the pitch/roll offset compensation procedure
(Procedure A-1, Section 7.11.1) can be used to evaluate a candidate site for magnetic
disturbances and determine whether it is a suitable location to perform the magnetometer
calibration procedure. The magnetometer calibration procedure itself contains the logic to
simultaneously survey the location for magnetic cleanliness while it is computing the
magnetometer calibration parameters.
In order to evaluate a candidate site, the Magnetometer Calibration Procedure must be
performed twice: once turning clockwise around the site, and once turning counter-clockwise.
Both times, the procedure should be conducted as described in Section 7.11.3 of this
document, with the exception of the direction of turns around the site.
NOTE
Although Section 7.11.3 indicates that the Magnetometer Calibration
Procedure should be performed by making a series of clockwise turns
around the site, the procedure can also be performed by making
counter-clockwise turns for the purpose of evaluating the site for
magnetic disturbances.
If the PFD displays the “CALIBRATION SUCCESSFUL / SITE IS CLEAN” message upon
completion of the Magnetometer Calibration Procedure in each clockwise and counterclockwise direction, then the candidate site is sufficiently free of magnetic disturbances and is
acceptable for performing the Magnetometer Calibration Procedure. It is important to obtain
successful result in both the clockwise and counter-clockwise directions to ensure that the
magnetometer sweeps over a large enough area at the candidate site.
If the PFD displays either the “MAG FIELD AT SITE NOT UNIFORM” or “MAG FIELD AT SITE
DIFFERS FROM IGRF MODEL” message upon completion of the Magnetometer Calibration
Procedure in either of the two directions, then the site contains magnetic disturbances that are
too large.

Revision 3
Procedure B: GRS 79 or GRS 77 and GMU 44 Magnetic Calibration
NOTES
Procedure A-1 (Section 7.11.1) must first be successfully accomplished before
performing Procedure B, only for situations where the GRS was replaced with
a new unit.
On the calibration pages, “GRS” refers to whichever GRS unit is installed.
1. Start the aircraft engine following the procedures referenced in the appropriate
Beechcraft AFM as listed in Table 1-1.
2. After aircraft engine startup, taxi the aircraft to a properly calibrated compass rose.
3. At the compass rose, align the aircraft to a heading of magnetic north (5°).
CAUTION
Calibration Procedure B must be carried out on a compass rose in order to
guarantee measurements free of environmental magnetic disturbances.
Attempting to carry out this maneuver on a typical ramp area may not yield a
successful calibration. The accuracy of the AHRS cannot be guaranteed if this
calibration is not performed on a magnetically clean compass rose or
equivalent. If the compass rose condition is not known, it is recommended that
the technician follow the guidance in Section 7.11.2.
4. Restart the PFD in configuration mode.
5. Go to the GRS Page Group on the PFD.
6. Select the GRS/GMU Calibration page and enter the following softkey password:

9

10


7. Use the FMS small knob to highlight GRS for calibration and press the ENT key.
8. Using the FMS small knob, select MAGNETOMETER. Press the ENT button.
9. Use the cursor to highlight the first step in the BEFORE CALIBRATION window.
10. Follow the checklist items displayed on the PFD and press the ENT key as each one is
completed or confirmed. When the CALIBRATE field is blinking, press the ENT key to
begin the procedure.
11. The PFD display advises the operator when to turn the aircraft, when to stop, and when
to turn again.
12. Upon instruction to turn, taxi the aircraft in a right turn. After approximately 25° to 30° of
turn from the last heading, the PFD display advises the operator to stop the aircraft.
NOTE
Due to the difficulties in executing smooth, accurate turns the PFD may
incorrectly interpret a station and instruct to “HOLD POSITION” prior to full
completion of a 30 turn. If this scenario is encountered, it is best for the
G1000 Supplemental Maintenance Manual
Textron Aviation G36/G58
190-02128-05
Page 7-37
Revision 3
operator to ignore the “HOLD POSITION” command and instead use outside
references to complete the approximate 30 turn. Instead of using the PFD
instruction to turn as a real-time indication of when to turn, simply judge the 30°
(±5°) turn increments of the aircraft by using the compass rose radials.
Dwelling at these 30 increments for the time recommended by the PFD should
result in successful calibration.
13. The PFD guides the operator to dwell at multiple headings around a complete circle.
NOTE
Due to high winds or excessive airframe vibration, the operator may encounter
a condition where the PFD restarts the 18-second countdown without full
completion of the previous countdown. If this is encountered more than once
for a given station, the operator should begin turning to the next station
(approximately 30). A minimum of 2 successful stations per quadrant is
required, where a successful station is a full 18-second countdown followed by
instruction to move. Ensure that at least 2 stations per quadrant are completed.
Thus, it may sometimes be required to dwell at a station after a countdown
restart.
A maximum of 30 stations is allowed for the entire calibration
procedure. If too many countdown restarts are encountered, the calibration
will fail with the message, “TOO MANY STATIONS.”
14. Repeat the turn-and-stop process until the PFD advises that a successful calibration is
complete. The GRS AHRS then enters its normal operational mode. Press the ENT
button on the PFD to conclude this procedure.

Procedure D: Engine Run-Up Vibration Procedure
NOTES
On the calibration pages, “GRS” refers to whatever GRS unit is installed.
Calibration Procedure D is performed in order to guarantee that the AHRS
mounting is sufficiently rigid and insensitive to vibration. This procedure must
be performed for both GRS units installed in the aircraft. Calibration
Procedures A1 and B (Sections 7.11.1 and 7.11.3 respectively) are not
required prior to this procedure.
Figure 7-6, GRS/GMU Calibration, Engine Run-Up
1. Restart the PFD in configuration mode.
2. Use the FMS small knob to highlight GRS 1 for calibration and press the ENT key. The
SELECT PROCEDURE field is not blinking.
3. Initiate the AHRS engine run-up vibration test procedure by performing the following
steps:
a) Select the ENGINE RUN-UP TEST procedure and press the ENT key.
b) Follow the checklist items displayed on the PFD, and press the ENT key as each one is
completed or confirmed. When the CALIBRATE field is blinking, press the ENT key to
begin the procedure.
4. The PFD display instructs the operator to gradually increase power from idle to full
throttle and back to idle over a period of 1-2 minutes.
5. When the operator has completed the engine run-up and the engine is back to an idle
setting, press the ENT key to indicate that the process is complete. When this is done,
the TEST COMPLETE field stops blinking.

6. The PFD informs the operator if the installation has passed or failed the vibration test. If
the test fails, the specific measurements causing the failure are identified and associated
numeric values are displayed on the PFD.
NOTE
Should a failure occur, the technician may perform the Engine Run-up test up
to 3 times successively before corrective action must be taken. If the test does
not pass after three attempts, then the installation should not be considered
reliable until the source of the vibration problem is identified and remedied. In
the event of repeated failure of the engine run-up test, record the values that
are reported to be out of range for future reference.
Performing this test on a windy day may cause a failure of the test. It
may be required to retest when the wind is not as strong or to reposition the
aircraft such that it isn’t affected by the wind.
The following are potential causes for failure of the engine run-up test:
a) Vibration motion of GRS and/or GMU44 caused by neighboring
equipment and/or supports.
b) Mounting screws and other hardware for GRS and/or GMU44 not firmly
attached.
c) GRS connector not firmly attached to unit.
d) Cabling leading to GRS or GMU44 not firmly secured to supporting
structure.
e) An engine / propeller that is significantly out of balance.
7. Press the ENT key on the PFD to conclude this procedure, then the aircraft can be taxied
back and the engine can be shut down for final testing. Continue to Section 7.11.5.

verification.
2. Ensure that the transmitter or receiver (RX/TX) that you are testing is significantly closer
to the ramp tester than another operating RX/TX, or erroneous and inaccurate results
may occur. All four quadrants (0, 90, 180 and 270 degrees) will be similarly tested to
verify bearing of simulated intruder supplied via the ramp tester are correctly displayed on
the MAP-TRAFFIC MAP page of the MFD.

3. Set up a stationary intruder by selecting the following on the ramp tester:

Intruder type: ATCRBS.

Intruder Start Distance: 2 nm

Intruder Start Altitude: 600 feet above field elevation

Vertical Speed: 0 fpm

Velocity: 0 kts (on some ramp testers, a velocity greater than 0 kts is required and
a stationary intruder is created by not starting the scenario.)
4. Position ramp tester at 0 degrees.
5. Initiate the intruder scenario and verify a target is annunciated on the MAP-TRAFFIC
MAP page of the MFD at the correct bearing of approximately 0 degree azimuth at 2 NM
and co-altitude (read as +06 above a filled diamond indicating proximate traffic).
6. On the ramp tester, toggle intruder traffic to standby or off.
7. Reposition ramp tester and reengage the same intruder scenario for 90, 180 and 270
degrees.
8. Verify a target is annunciated on the MAP-TRAFFIC MAP page of the MFD at the same
bearing as the ramp tester.
9. If the bearing is not as anticipated or multiple targets are displayed during tests, verify the
following:

Coax cable connectors are properly secured at the bulkhead adapter fittings, GA
58 antennas, and GTS unit

Connections are made to the proper channels and color-coded heat shrink is the
same color on both ends of coax cables

Connectors are correctly installed on coax cables.
Note: These tests are conducted at field elevation. Additional local traffic targets may appear
and are not an indication of improper system operation.
Note: When an IFR6000 ramp tester is used with a GTS 800, the IFR6000 must be configured
for a distance that is 4 times the actual distance. For example, if the ramp tester is located 10 ft
away from an aircraft, the IFR6000 should be configured as if it were 40 ft away from the aircraft.
This will adjust the MTL setting of the IFR6000 such that it will see the GTS 800 low power
interrogations and reply to the interrogations.

Intruder Start Altitude : 600 feet above field elevation

Vertical Speed: 0 fpm

Velocity:600 kts
4. Initiate the intruder scenario and observe the following:

Traffic should be acquired at approximately 10 NM at 90 degree bearing and coaltitude. Observe intruder closes on own aircraft at a rate of 0.1 NM/sec. Verify
that only a single target is displayed in the expected quadrant.

The intruder should transition from Other Traffic (displayed as an open diamond
with +06 displayed above), to proximate traffic (displayed as a filled white
diamond with +06 displayed above), to a Traffic Advisory (TA) alarm (yellow filled
circle with +06 displayed above.)
NOTE
The aural TA annunciations are muted if the height above terrain is below
400 feet.
Note: When an IFR6000 ramp tester is used with a GTS 800, the

The following test assures the antennas and coaxial cables are properly connected. The GTS
800 must be in Ground Test mode.
1. On the Map – Traffic Map page of the MFD, press the TAS OPER softkey. A self-test
of the antenna circuit is initialized. If the MFD displays FAILURE at the upper left corner
of the traffic display area, it will be necessary to recheck the coaxial connections. If MFD
displays OPERATE without indicating a fault, proceed to the next step of antenna
verification.
2. Ensure that the transmitter or receiver (TX/RX) that you are testing is significantly closer
to the ramp tester than another operating RX/TX, or erroneous and inaccurate results
may occur. All four quadrants (0, 90, 180 and 270 degrees) will be similarly tested to
verify bearing of simulated intruder supplied via the ramp tester are correctly displayed on
the Map – Traffic Map page of the MFD.
3. Set up a stationary intruder by selecting the following on the ramp tester:

Intruder type: ATCRBS.

Intruder Start Distance: 2 nm

Intruder Start Altitude: 600 feet above field elevation

Vertical Speed: 0 fpm

Velocity: 0 kts (on some ramp testers, a velocity greater than 0 kts is required and
a stationary intruder is created by not starting the scenario.)
4. Position ramp tester at 0 degrees.
5. Initiate the intruder scenario and verify a target is annunciated on the Map – Traffic Map
page of the MFD at the correct bearing of approximately 0 degree azimuth at 2 NM and
co-altitude (read as +06 above a filled diamond indicating proximate traffic).
6. On the ramp tester, toggle intruder traffic to standby or off.
7. Reposition ramp tester and reengage the same intruder scenario for 90, 180 and 270
degrees.
8. Verify a target is annunciated on the Map – Traffic Map page of the MFD at the same
bearing as the ramp tester.
9. If the bearing is not as anticipated or multiple targets are displayed during tests, verify the
following:

Coax cable connectors are properly secured at the GA58 antennas and GTS unit.

Connections are made to the proper channels and color-coded heat shrink is the
same color on both ends of coax cables

Connectors are correctly installed on coax cables
10. If no other service is to be performed, continue to the return-to-service checks in Section
9.

Ramp Test
The following test provides a scenario that will converge and intercept the GTS 800 to assure
proper operational and surveillance functions.
1. On the Map – Traffic Map page of the MFD, press the TAS OPER softkey.
2. Position ramp tester at 90 degrees.
3. Select the following on the ramp tester:

Intruder type: ATCRBS.

Intruder Start Distance: 10 nm

Intruder Start Altitude: 600 ft above Field Elevation

Vertical Speed: 0 fpm

Velocity: 600 kts
4. Initiate the intruder scenario and observe the following:

Traffic should be acquired at approximately 10 NM at 90 degree bearing and coaltitude. Observe intruder closes on own aircraft at a rate of 0.1 NM/sec. Verify
that only a single target is displayed in the expected quadrant.

The intruder should transition from Other Traffic (displayed as an open diamond
with +03 displayed above), to proximate traffic (displayed as a filled white
diamond with +03 displayed above), to a Traffic Advisory (TA) alarm (yellow filled
circle with +03 displayed above.)
NOTE
The aural TA annunciations are muted if the height above terrain is
below 400 feet.
If no other service is to be performed, continue to the return-to-service checks in Section 9.

GFC 700 Autopilot Clutch Overpower Check
The basic operation and checkout of the GFC 700 AFCS is not changed by this STC. Refer to
the G36 or G58 Aircraft Maintenance Manual for specific procedures for the GFC 700 AFCS.
Refer to Section 4.7 for the GSM 86 servo gearbox spring cartridge torque check.
NOTE
The GFC 700 uses electronic torque limiting as well as mechanical clutches to
limit the maximum servo effort. When the system is on the ground, the
electronic torque limiting is removed, allowing manual checks of the clutch
settings.
1. Move the flight controls through their full range motions. Check for any signs of binding
or resistance.
2. Engage the Autopilot by pressing the AP key.
3. Manually overpower the autopilot clutches in pitch, yaw, and roll.
4. Actuate and hold PITCH TRIM switch in either the NOSE UP or NOSE DOWN direction
to disconnect the autopilot. While the trim is running, restrain the aircraft pitch trim
wheel and verify that the trim clutch can be overpowered.
5. Verify that the trim wheel moves smoothly in both directions throughout the entire trim
range during manual electric trim operation. If the trim wheel hesitates, this may indicate
that the pitch trim servo gearbox clutch is slipping. Verify GSM 86 servo gearbox torque
and cable tension.
6. If the autopilot servo cannot be overpowered during any of the preceding steps, check
the GSM 86 servo gearbox torque per Section 4.7.
