Installation Overview
4.1 General Handling Recommendations
4.1.1 ESD Handling Recommendations
To avoid damage to the AT-1, take precautions to prevent Electrostatic Discharge (ESD)
when handling the unit, connectors, and associated wiring. ESD damage can be prevented
by touching an object that is of the same electrical potential as the unit before handling
the unit itself.
4.2 Workmanship
Installation of avionics equipment into an aircraft is a complex task that requires expert skills
and know-how. While some installation practices may lead to quicker results, only practices
that provide for excellent durability and reliability are acceptable. As many avionics systems
have a life cycle of several decades, a durable and reliable installation in compliance to strict
workmanship standards is of utmost importance.
4.2.1 Workmanship
‘‘Workmanship is defined as the control of design features, materials and assembly processes
to achieve the desired durability and reliability for subassembly interconnections, specifically
those in printed wiring assemblies and cable harnesses, and the use of inspection techniques
and criteria to assure interconnect quality.Workmanship promotes standardized designs
and fabrication practices to enhance assembly durability and reliability and restricts the
use of designs and manufacturing processes known to reduce those qualities.’’
4.2.2 Standards
Always follow acceptable avionics installation practices. Installation must always
follow regulatory requirements.
Many military or civil standards for avionics installations are acceptable.
NASA Workmanship Standards
As an addition to regulatory requirements we recommend installation in accordance to
NASA WORKMANSHIP STANDARDS. These standards provide for an excellent overview
and in-detail knowledge on acceptable practices including explanations and a pictorial
reference. NASA WORKMANSHIP STANDARDS are publicly available on this website:
