2. System Description

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

components on the Piper PA-46-500TP Malibu Meridian. This section briefly describes the

function of these components.

2.1 Equipment Descriptions

2.1.1 GCU 476

The GCU 476 controller is shown in Figure 2-1. This is an updated version of the existing GCU

476 remote FMS controller. The controller is updated with improved joystick function. This is a

drop-in replacement.

2.1.2 GDU 1050 / 1550

The GDU 1050 display unit is shown in Figure 2-2. The GDU 1050 is used as the primary flight

displays (PFDs) mounted in the cockpit. The GDU 1050 displays are an update to the existing

GDU 1040s that were originally installed. The new displays have the same overall dimensions

as the previous generation hardware, with physical controls and labeling being identical to the

previous versions. The new GDU 1050 displays contain a new LED backlight, and updated

electronics, including a multi-core microprocessor.

The GDU 1550 display unit is shown in Figure 2-3. The GDU 1550 is used as a multifunction

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

1500 that was originally installed for the MFD.

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 476. 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 checklist must be saved as a

“PA-46-500TP.gcl” file for the checklist function to work.

The Checkset tool can be downloaded from the Garmin website

(https://www8.garmin.com/support/download_details.jsp?id=12032). 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 one of

the top right MFD card slots. 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.

provides ADS-B Out.

2.1.5 GTX 345R

The GTX 345R transponder is shown in Figure 2-4. The GTX 345R replaces the existing #1

GTX 33 w/ES Mode S transponder with a GTX 345R ADS-B transponder when the existing #1

transponder is a non-diversity transponder on the aircraft. The GTX 345R provides ADS-B Out.

The GTX 345R’s datalink provides traffic (TIS-B and air-to-air) and weather (FIS-B) data for

display on the PFD’s and MFD.

2.1.6 GTX 345DR

The GTX 345DR transponder is shown in Figure 2-4. The GTX 345DR replaces the existing #1

GTX 33D w/ES Mode S transponder with a GTX 345DR ADS-B transponder when the existing

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.

The periodic test value is the value allowed during the bonding checks specified in Section 4.

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

(reference ARP 1481 for corrosion control between dissimilar metals). Materials should be

galvanically compatible, reference ARP 1870 Table 2. 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 5.5. 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 burnished, 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 Piper Aircraft, Inc. PA-46-500TP, Malibu

Meridian (G1000) Maintenance Manual (P/N 767-072) or ARP 1841 (dissimilar metals) 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, reference ARP 1870 Table 2. When corrosion protection is removed to make an

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

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 PFD 1, PFD 2, 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 switch to ON.

2. Open the MFD, PFD 1, PFD 2 circuit breakers; ensure the BATTERY switch is off (not

illuminated).

3. Press and hold the ENT key on PFD 2 (copilot) and close the PFD 2 circuit breaker.

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

PFD 2.

5. Press and hold the #12 (far right) softkey on the MFD and close the MFD circuit breaker.

6. Release the #12 softkey after ‘INITIALIZING SYSTEM’ appears in the upper left corner

of MFD.

7. Press and hold the ENT key on PFD 1 (pilot) and close the PFD 1 circuit breaker.

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

PFD 1.

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.

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.

If a software loader card is inserted in the top slot of the display before it is

powered on, the display will automatically enter configuration mode and the

technician does not need to press and hold a softkey at power-on.

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.

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

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 avionics unit. See Section 5 for more details on troubleshooting.
