2-9: For More Information
Depending on what your “mission” is, you may want a simple VFR system, or an IFR
system with many built-in redundancies. The GRT system enables customization for the
entire range of possible configurations, from simple to sophisticated, depending on the
builder’s desire and skill level.
While this manual covers the very basics of EFIS wiring and communication, along
with GRT Sport-specific details, there are many very important safety aspects of
aircraft wiring that we cannot even begin to discuss in this manual. The techs at
GRT recommend the following sources for more information on proper aircraft
avionics & electrical system design:
•
The “Aeroelectric Connection” by Bob Nuckolls is a great place to start. It covers
everything from the very basics of electricity to the proper design and installation
of sophisticated IFR-capable systems.
•
EAA columnist Tony Bingelis’s books have long been a staple of experimental
aircraft builder knowledge. In addition to wiring considerations, Mr. Bingelis
discusses all aspects of kitplane building, from spinner to tail. The books are:
The
Sportplane Builder: Aircraft Construction Methods
,
Sportplane Construction
Techni
ques: A Builder’s Handbook
,
Firewall Forward: Engine Installation Methods
and
Tony Bingelis on Engines
.
•
FAA Advisory Circular 43.13-
2B provides the “certified” reference for safe and
durable aircraft wiring techniques, though it is a bit outdated. It is available online
as a free download from www.faa.gov.
•
The Experimental Aircraft Association has compiled a collection of videos called
“Hints for Homebuilders” on its website, www.eaa.org. A quick search through
these will give you valuable hints on various wiring topics, including properly
crimping D-sub/Molex connector pins.
