Pitot and Static plumbing parts are aircraft specific, see Section 4.1.4. The following installation materials may be required depending on the installation, but are not available from Garmin: •...
3.4.1 GPS Antenna A GPS signal is required. The G5 can use an external GPS antenna or GPS data from one of the GPS navigators or GTX 3x5 listed in Section 5. In a dual G5 installation only the G5 Attitude requires the GPS position input. The GPS information is communicated to the G5 DG/HSI over the CAN Bus.
3.4.1.1 GARMIN ANTENNAS Table 3-7 lists Garmin antennas supported by the G5. The GA35 and GA36 meet the requirements of TSO/ETSO-C144. Table 3-7 Supported Garmin Antennas Model Connector Type Part Number GA35 013-00235-0X GA36 013-00244-0X GA56 011-00134-00 3.4.1.2 NON-GARMIN ANTENNAS Table 3-8 lists non-Garmin antennas supported by the G5.
AC 43.13 Chapter 11 Section 17. Install wiring in accordance with AC 43.13-1B Chapter 11, Sections 8 through 13. Record the aircraft wire routing in Appendix C of Garmin G5 Electronic Flight Instrument Part 23 AML STC Maintenance Manual including Instructions for Continued Airworthiness, P/N 190-01112-11.
3.4.5.2 CAN Bus The primary digital interface used to exchange data between the G5 Attitude indicator, GMU 11 and GAD 29/29B is the Controller Area Network, also known as the CAN bus. CAN was developed by Bosch GmbH in the 1980s, and its specifications are currently governed by ISO 11898-2.
At each of the two extreme ends of the CAN bus backbone, a 120 Ω resistor is installed to terminate the bus. In the G5 system, separate resistors are not required. Instead, termination resistors are provided either via termination adapters that plug into an LRU’s CAN connection or via an internal resistor.
Page 32
Refer to Section 3.2.1 for recommended coaxial cable types. 3.4.6 Cooling Requirements While no forced cooling air is required for the G5, GMU 11 or GAD 29/29B it is highly recommended that the air behind the panel be kept moving (by ventilation or a fan). Units tightly packed in the avionics stack heat each other through radiation, convection, and sometimes by direct conduction.
Page 33
For G5 installations utilizing the RS-232, CAN bus and ARINC 429 interfaces, terminate the shield to the G5, GMU 11 and GAD 29/29B connector backshells as shown in Figure 4-42 and Figure 4-43. For shield terminations at the GPS or VHF Navigator follow the appropriate installation techniques as indicated by the manufacturers installation instructions for that unit.
If installing dual G5s above and below each other, a minimum spacing of 3.6 inches center to center is required, see Section 4.1.2.4 for more information. • Two Adapter Plates must be used if installing the G5 in an instrument hole with any cutout for instruments knobs. See for more information.
Figure 4-1 Typical G5 Installations for IFR Approved Aircraft A G5 can be installed in an instrument panel that does not have an existing attitude indicator or DG/HSI. In these cases, the G5 must be located on the Pilot’s instrument panel, and centered as nearly as practicable about the vertical plane of the pilot’s forward vision.
