System Description

The G1000 NXi system components described in this section are additions or updates to

existing components on the Textron Aviation inc. Model 510. This section briefly describes the

function of these components.

2.1

Equipment Descriptions

2.1.1 GCU 475

The GCU 475 controller is shown in Figure 2-1. This is an updated version of the existing GCU

475 controller. The controller is updated with improved joystick function. This is a drop-in

replacement.

2.1.2 GDL 69A SXM

The GDL 69A SXM satellite receiver is shown in Figure 2-2. The GDL 69A SXM is a data link to

utilize currently available SirusXM satellite data services. This is an update to the existing GDL

69A and is a drop-in replacement.

2.1.3 GDU 1050A

The GDU 1050A display unit is shown in Figure 2-3. The GDU 1050A is a primary flight display

(PFD) mounted in the cockpit. The GDU 1050A is an update to the existing GDU 1040A that

was originally installed. The GDU 1050A improves display quality and brightness, improves

processing time and responsiveness, and improves weight and power consumption.

2.1.4 GDU 1550

The GDU 1550 display unit is shown in Figure 2-4. The GDU 1550 is a multifunction flight

display (MFD) mounted in the cockpit. The GDU 1550 is an update to the existing GDU 1500

that was originally installed. The GDU 1550 improves display quality and brightness, improves

processing time and responsiveness, and improves weight and power consumption.

Electronic Checklist

The Electronic Checklists (ECL) function allows the user to view and interact with aircraft

checklists. The Checklist contents are displayed on the GDUs and the checklist control is

performed using the GCU 475. The Garmin Checkset tool is provided by Garmin at no charge to

the aircraft operator to generate and edit the custom checklist files which are saved in the .gcl

format.

NOTE

For the G1000 NXi update, the name of the checklist has to be saved as

“510R7AJ.gcl” for the checklist function to work.

The Checkset tool can be downloaded from the Fly.Garmin website under the Tools tab

(https://fly.garmin.com/fly-garmin/). The checklist is created or edited by the OEM/End user

without involvement from Garmin. Once the electronic checklist is created by the OEM/end user,

it is then downloaded onto an SD card and inserted into the top or bottom MFD card slot. Upon

power-up, the G1000 system checks the MFD SD cards for any checklist files and then

transfers the electronic checklist to the GDU internal memory. Once the Checklist is transferred

to the GDU, the SD card containing the checklist files can be removed and is no longer

required.

Please note that operational usage of the checklist file may require regulatory approval. The

OEM/Operator is expected to obtain the required approval.

In for TIS-B and air-to-air traffic and FIS-B weather data to the G1000 NXi system for display to

the flight crew.

2.1.7 FS 510

The FS 510 (Flight Stream 510) wireless data card is shown in Figure 2-7. The FS 510 is an

SD card that installs into the MFD in the aircraft cockpit. The FS510 offers the addition of Wi-Fi

and Bluetooth connectivity for activities such as flight plan transfers and data output to carry-on

devices such as tablets and electronic flight bags. This data may be in the form of GPS

information, weather, aircraft traffic, or other items for flight crew use.

2.4 Electrical Bonding

For the purposes of this STC, aircraft ground reference definitions vary according to airframe

type, as defined in Table 2-2. Refer to the periodic test and reconditioned resistance values

corresponding to these ground reference definitions when performing the equipment bonding

tests in Section 4.5.

The periodic test value is the value allowed during the bonding checks specified in Section 4.5.

The reconditioned value is the value allowed on initial installation or if the bond must be

reworked if the periodic test value is exceeded.

Refer to SAE ARP 1870 Section 5 when surface preparation is required to achieve electrical

bond.

2.4.1 Consideration for Untreated or Bare Dissimilar Metals

The correct material finish is important when mating untreated or bare dissimilar metals.

Materials should be galvanically compatible. When corrosion protection is removed to make an

electrical bond any exposed area after the bond is completed should be protected again.

Additional guidance can be found in SAE ARP 1870 Section 5. Typical electrical bonding

preparation examples are shown in Figure 2-9, Figure 2-10, and Figure 2-11.

2.4.2 Preparation of Aluminum Surfaces

The following general procedure is recommended to prepare an aluminum surface for proper

electrical bonding.

1. Clean grounding location with solvent.

2. Remove non-conductive films or coatings from the grounding location.

3. Apply a chemical conversion coat such as Alodine 1200 to the bare metal.

4. Once the chemical conversion coat is dry, clean the area.

5. Install bonding equipment at grounding location.

6. After bond is complete, if any films or coatings were removed from the surface, reapply a

suitable film or coating to the surrounding area within 24 hours.

After satisfactory electrical bond is achieved, when it has been necessary to remove any high-

resistance protective coating, the area from which the coating has been removed should be

refinished with the same finish as is on the rest of the part within 24 hours. In cases where the

parts come in with certain areas spot-faced, or if there is no finish on the part (bare metal), apply

conformal coating over the bond joint and hardware per MIL-I-46058 or clear lacquer per TT-L-

20A to facilitate future inspection. Refer to the model specific Aircraft Maintenance Manual or

Standard Practices Manual for surface protection requirements applicable to affected areas.

The correct material finish is important when mating untreated or bare dissimilar metals. They

should be galvanically compatible. When corrosion protection is removed to make an electrical

bond, any exposed area after the bond is completed should be protected again. Additional

guidance can be found in SAE ARP 1870 Section 5.

For a more detailed procedure, refer to SAE ARP 1870 Sections 5.1 and 5.5.

3. Control and Operation

3.1 Configuration Mode Overview

Throughout this document, references are made to the PFD1, PFD2, 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 NXi sub-systems.

Troubleshooting and diagnostics information can be viewed in this mode.

To start the G1000 NXi system in configuration mode, follow these steps;

1. Apply power to the G1000 NXi system by applying aircraft EXT power, set the

AVIONICS MASTER PWR and BATT switches to ON.

2. Pull the MFD (PRIM and SEC), PFD1 (PRIM and SEC), and PFD2 (PRIM and SEC)

circuit breakers.

3. Press and hold the ENT key on PFD 2 (co-pilot’s side) while applying power using the

PFD2 PRIM circuit breaker.

4. Release the ENT key after ‘INITIALIZING SYSTEM’ appears in the upper left corner of

PFD2.

5. Press and hold the far right softkey on the MFD while applying power using the MFD

PRIM circuit breaker. Note that the ENT key on the GCU 475 controller may be used

after initial software loads.

6. Release the softkey after ‘INITIALIZING SYSTEM’ appears in the upper left corner of the

MFD.

7. Press and hold the ENT key on PFD1 (pilot’s side) while applying power using the PFD1

PRIM circuit breaker.

8. Release the ENT key after ‘INITIALIZING SYSTEM’ appears in the upper left corner of

PFD1.

IMPORTANT

The 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. Most protected page content is viewable to allow system

awareness for troubleshooting.

NOTE

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.

3.1.1 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.

Garmin G1000 NXi System Maintenance Manual 190-02450-01

Textron Aviation Inc. Model 510 Citation Mustang Revision 1

Page 18

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).

 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

Garmin G1000 NXi System Maintenance Manual 190-02450-01

Textron Aviation Inc. Model 510 Citation Mustang Revision 1

Page 19

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).

A blank active column, as shown in Figure 3-2, represents loss of communication between the

display and the particular unit. See Section 5 for more details on troubleshooting.

Figure 3-2, Loss of Communication

3.1.2 Configuration Prompts

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

3.1.3 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.
