    G900X/G950 Installation Overview 1.1 Introduction This manual provides an overview of the G900X/G950 Integrated Flight Deck and its mechanical and electrical installation aspects. The system design is flexible and can accommodate different aircraft applications. The following outline describes the organization of this manual: This section contains a basic overview of the G900X/G950 system and interface.

  • Page 10: System Overview

    3 party autopilots. The G900X is intended for use on experimental (not Type Certificated) aircraft, while the G950 system is intended for use on select aircraft certified under FAR Part 23 regulations. The G950 is a fixed configuration of the G1000 integrated flight deck.
  • Page 11 1.2.2 System Architecture The following diagrams illustrate the redundant communication paths that are in place in a typical G900X/G950 installation.

  • Page 16 005-00217-85 1.3.5 Cooling Requirements External cooling is required for the GIA 63W, GDU 1040, and GTX 33. External cooling is optional for all other G900X/G950 LRUs. When external cooling is required the following guidelines should be followed: • All external cooling fans should be connected to their own circuit breaker. If this is not possible, all external cooling fans should be combined on the same circuit breaker as the LRU they are cooling (proper circuit breaker sizing considerations must be taken into consideration).
  • Page 17 1.3.5.1 GDU 1040 Cooling Requirements External cooling of the GDU 1040 is required. A fan bracket (Garmin P/N 115-00973-00) is available to mount an axial fan (Garmin recommended fan 013-00102-00, See Table 1-6) to the system rack. The bracket is designed to secure a 2.36 x 2.36 inch (60 x 60 mm) axial fan. See Appendix E for dimensions and assembly instructions.
  • Page 18 Alternatively, the following fans have been evaluated and reportedly meet the minimum specification of 20 cfm airflow. This information is provided for reference only. Garmin makes no claims on the quality or performance of these alternate cooling fans. Table 1-7. Alternate GDU 1040 Cooling Fans and Specifications...
  • Page 19 It is recommended that a 3 port blower fan is used with an airflow rating of 5 cfm per port or greater. See Table 1-8 for Garmin recommended fans.
  • Page 20 Thermal Validation Plan, Garmin part number 190-00313-51 Although Garmin strongly recommends that all installations perform thermal validation tests as described in the above documents, G900X systems may alternately comply by installing cooling fans in accordance with the guidelines provided herein.

  • Page 21: Mechanical Aspects

    The G900X/G950 mounting system is designed to simplify the installation, removal, and servicing of G900X/G950 LRUs. The system typically consists of a main system rack, LRU racks, and any required cooling accessories or other structural supports mounted behind the instrument panel. The GDU 1040 PFD and MFD mount to the instrument panel cutout directly in front of the main system rack.
  • Page 22 1.4.2.1 Recommended LRU Clearance Refer to Table 1-9 and Figure 1-6 for recommendations on Garmin LRU clearance and wire bend radius specifications. Garmin recommends that adequate space be left, so LRUs can be maintained properly in the event that an LRU needs to be removed and/or replaced.

  • Page 23: Rack Installation

    Two racks are available under the following part numbers (Refer to Figure 1-7 and Appendix E for pictures and dimensions). The Standard Main System Rack is included in the basic G900X/G950 installation kit. The Truncated Main System Rack can be purchased separately. Table 1-10. Main System Racks...
  • Page 24 (see Appendix E). It is strongly recommended that all LRU racks be assembled to the main rack before mounting the main rack to the aircraft. Figure 1-8. Main System Racks Page 1-16 G900X/G950 Installation and Maintenance Manual – G900X Installation Overview Revision D 190-00719-00...
  • Page 25 LRU racks can also be mounted independently of the main rack. Figure 1-9. LRU Racks G900X/G950 Installation and Maintenance Manual – G900X/G950 Installation Overview Page 1-17 190-00719-00...
  • Page 26 Ensure that the wire harness is properly attached to the rear plate and does not hinder the slight movement of the plate. Figure 1-10. Floating Rear Plate Installation Page 1-18 G900X/G950 Installation and Maintenance Manual – G900X Installation Overview Revision D 190-00719-00...
  • Page 27 Preferred nutplate kits (011-00915-XX) are best suited for use with a Garmin system rack. Alternate nutplate kits (011-01148-XX) are typically used when the LRU rack is not mounted in a Garmin system rack or other constraints do not allow the use of the preferred nutplate kits.
  • Page 28 Figure 1-12. Example of Three Position Nutplates Page 1-20 G900X/G950 Installation and Maintenance Manual – G900X Installation Overview Revision D 190-00719-00...
  • Page 29 LRU binds or is caught, stop and remove it. Check and ensure that the rear plate and connectors are floating freely in the LRU rack before attempting to re-install. Figure 1-13. Locking System G900X/G950 Installation and Maintenance Manual – G900X/G950 Installation Overview Page 1-21 190-00719-00...
  • Page 30 1.4.10 Keyplates Figure 1-14. Keyplate/LRU Relationship Some G900X/G950 LRU racks employ a keyplate/hex-dowel system that mates with the back of certain units and their rear plates. This prevents another similarly sized unit from being inserted into the incorrect rack and potentially damaging the connectors. Each keyplate is paired with an opposite mating plate as shown in Figure 1-14 and Table 1-14.
  • Page 31 (see Figure 1-15), which is attached to the right-most slot on the main system rack. This aligns the harness with the GDU 1040 display’s connector. For CHiPS installation instructions and drawings, refer to Appendix E. Figure 1-15. CHiPS Harness G900X/G950 Installation and Maintenance Manual – G900X/G950 Installation Overview Page 1-23 190-00719-00 Revision D...

  • Page 32: Electrical Considerations

    All Garmin fault tree analysis documentation provided with the G950 system does not take into account any failures of the power bus as this is highly dependant on the specific aircraft configuration Therefore, it is highly recommended for G950 systems to be powered by dual independent power sources to meet required failure probability limits for certification.
  • Page 33 615725 M81969/1-04 NOTES 1. Non-Garmin part numbers shown are not maintained by Garmin and consequently are subject to change without notice. 2. Extraction of 16 and 18 AWG contacts requires cutting off the wire barrel from the contact. It may also be necessary to push the pin out from the face of the connector when using an extractor.

  • Page 34: Cable Installation

    1.5.5 Backshell Assemblies Connector kits include backshell assemblies. Garmin’s backshell connectors give the installer the ability to quickly and easily terminate shield grounds at the backshell housing. To assemble the backshell connectors and Shield Block grounding system, refer to Section 13 for Shield Block installation instructions.
  • Page 35 (except Display Units which shall be less than 20 milliohms) to local structure to where the equipment is mounted. Compliance should be verified by inspection using a calibrated milliohm meter or other equivalent means. G900X/G950 Installation and Maintenance Manual – G900X/G950 Installation Overview Page 1-27 190-00719-00...

  • Page 36: Antenna Considerations

    Locate it as far away as possible from transmitter antennas. Page 1-28 G900X/G950 Installation and Maintenance Manual – G900X Installation Overview Revision D 190-00719-00...
  • Page 37 A. The antenna(s) (Garmin P/N 010-10160-00) or equivalent should be mounted away from major protrusions, such as engine(s), propeller(s), and antenna masts. It should also be as far as practical from landing gear doors, access doors, or other openings that could affect the radiation pattern.
  • Page 38 No special precautions need to be taken to provide a bonding path between the GPS antenna and the aircraft structure.

    Garmin has included in this manual some installation guidelines to aid the builder in the placement of various units which make up the G900X. It is at the discretion of the builder whether he or she wants to follow a typical layout or design an installation completely unique to their aircraft. The following information is provided as guidance only and does not account for variations in specific installations.
  • Page 382 B.1.1 GRS 77 and GMU 44 The integrity and reliability of the G900X heading and attitude information is entirely dependent upon the installation quality of the GRS 77 AHRS and GMU 44 Magnetometer. Garmin strongly recommends the purchase of the pre-fabricated parts indicated in Table B-1. Failure to use Garmin approved brackets may result in severe degradation of system performance.
