any resistor with a better tolerance may be used.
•
120Ω (±5% or better), 0.25W resistors qualified to MIL-R-10509 or MIL-PRF-26
(i.e. RN60D1200FB14).
Note:
The ±5% tolerance stated is a minimum requirement and any
resistor with a better tolerance may be used.
•
Diode, 1000V, 1A, P/N 1N4007 (Note: The diode P/N may be amended with a suffix, this is
packaging-only information and does not affect form or function of the diode)
The following installation materials may be required depending on the installation, but are not available
from Garmin:
•
2024-T3 aluminum alloy sheet per AMS-QQ-A-250/4 or clad 2024-T3 aluminum alloy sheet per
AMS-QQ-A-250/5. Minimum sheet thickness requirements:
o
0.032" for GMU 11 magnetometer and GAD 13 supporting structure.
o
0.040" for GAD 29/29B, Glare Shield Mounted GPS Antenna supporting structures.
•
Aircraft grade fasteners e.g., AN525 screws, MS20426AD rivets, MS21059 rivet nut plates,
MS21071 reduced rivet spacing nut plates. NAS1832, NAS1834, or NAS1836 potted inserts
maybe required if honeycomb core panels are used to support the installation of G5 components.
•
Synthetic Fastener Tape, A-A-55126, used for mounting Glare Shield Mounted GPS Antenna
3.3 Test Equipment
The following test equipment is required to complete the G5 installation and to perform post-installation
checkout of the system:
•
Ground power cart (capable of supplying power to the aircraft systems and avionics)
•
Air data test set (e.g. Barfield DPS450 or similar)
•
VHF NAV test set
•
Low resistance ohmmeter
•
Digital Level (or equivalent)
The following equipment may be required based on the units being installed and the particular aircraft,
see Section 4.1 for information:
•
Laser Square
•
Protractor Tool
•
Plumb Bob
•
Aircraft Jack Set
3.4 Installation Considerations
The installation instructions are intended to be used in coordination with the avionics installation practices
in AC 43.13-1B and AC 43.13-2B.
•
Modification of existing plastic instrument panel overlays may be required to install the G5
electronic flight instrument.
•
Fabrication of a wiring harness is required.
•
Sound mechanical and electrical methods and practices are required to achieve optimum system
performance.
