A few weeks ago there was some discussion on the List about
noises from some AeroLed products. I cruised their website and
promised to inquire into the marketing philosophy for their
lighting products.
I had some good conversation with one of the principals,
a Mr. Nate Calvin. These guys are not the new kids on the
block. They've delivered product to some very sophisticated
customers who would demand careful scrutiny of mechanical
and electrical characteristics. Nate tells me that all
their product meets or exceeds DO-160 requirements for
conducted noise in small aircraft.
I'll remind readers that passing all the tests does not
mean ZERO noise emissions . . . only that they are below
the industry approved limits for this an all other electronics
offered to the type certificated aircraft market.
He recalled one case where an observed noise problem
turned out to be a design problem with an intercom
that was not fully vetted for living in the DO-160
world of light aircraft.
Bottom line is that AeroLed products are very low
risk for contributing to a noise issue. When they
are identified as an observable noise source, the
investigator should consider poor design of the victim
system and/or some form of installation error first.
