Jupiter Avionics offers the DO-160 gauntlet
S T O R Y

TESTING IS BUT ONE
ASPECT OF THE TOTAL
CERTIFICATION EFFORT.
MANUFACTURERS NOT
ONLY MUST DOCUMENT
EVERY STEP OF EACH TEST,
THEY MUST ALSO EXPLAIN
WHY THEY TESTED TO A
SPECIFIED LEVEL, OR WHY
THEY DID NOT TEST TO
ANOTHER LEVEL. AND THEY
HAVE TO TRACE EACH TEST
BACK TO THE REQUIREMENT
THAT CALLED FOR IT.

o earn certification from an aviation authority such as the Federal
Aviation Administration, Transport Canada or the European
Aviation Safety Agency, avionics equipment must run the
environmental gauntlet prescribed by RTCA DO-160, Environmental
Conditions and Test Procedures for Airborne Equipment. When it was
first published in 1975, according to Scott Moore, project manager and
environmental testing manager at Jupiter Avionics, DO-160 specified the
order in which the tests must be conducted. The test item had to endure
the shock and vibration tests before it began the humidity evaluation,
"the idea being that the preceding tests made the test unit more
susceptible to the one that followed," he said.
The latest version of the standard, DO-160G, specifies no order, he
continued, and those seeking certification can employ as many test
units as there are tests. Jupiter usually tests three: one undergoes the
majority of the DO-160 tests, the second faces those tests, like humidity
and lightning, with a high risk of resulting damage, and the third is a
spare standing ready to replace either of its mates that succumbs to the
environmental gauntlet.
What has not changed is the reality of DO-160 environmental
testing. It takes time and money, and the investment of both increases
significantly when testing reveals a problem that must be solved late in
the design process, Moore said. This is one reason why Jupiter started
