Description / Abstract:
This Report includes guidelines to be considered as part of the
electronic packaging design task. The applicability of any
particular section in this Report is dependent upon the environment
in which the avionic systems, subsystems, and cables are
located.
The applicability of these guidelines to the RTCA DO-160 test
conditions identified in ARINC Specification 650 can be determined
by reference to the Environmental Requirements/Guidance Cross
Reference Matrix shown in Table 1-1.
Table 1-1 identifies sections of RTCA DO-160 that define both
the physical and electromagnetic environmental conditions for
electronic equipment installed within the generic FAR/JAR Part 25
metallic aircraft. (twin-engined, wing-mounted turbojet).
The generic Part 25 aircraft type is divided into thirteen
environmental areas encompassing subsidiary zones in order to
address the environmental conditions defined within RTCA DO-160.
Conditions applicable to these areas and subsidiary zones for
specific aircraft are also detailed in the airframe manufacturer
specifications. Although there will possibly be more benign zones
within each area, equipment designs should take into account the
overall environmental conditions for the encompassing area. The
most current issue of any applicable standard, especially FAR/JAR
Part 25 and RTCA DO-160 apply.
