    Suppliers of product to the TC aircraft world
    are encouraged if not commanded to worship
    at that altars of the gods of blissful
    system integration.  Catechisms for these
    orders are documented in RTCA DO-160,
    Mil-Std-810, Mil-Std-704 just to name the
    most prevalent.

    By the time the system integrator is tasked
    with finding a place to bolt it in and wire
    it up to make it work, 99.99% of concerns
    for unhappy experience are already addressed.

    Even when the hardware has not been admitted
    to the social A-List for the aviation community,
    the risks for noise issues are relatively low.
    A single point ground for all the instrument
    panel mounted goodies and paying attention
    to the manufacturer's installation instructions
    goes a long way to crafting a noise free future.

    Ferrite beads are found useful only when the
    original designer of a potential noise
    antagonist/victim didn't do their homework.
    To assume that they would be useful before you've
    identified a real noise issue is probably not
    a good use of time . . . Fly the airplane
    first . . . the ferrites can probably
    be willed to the neighbor kid as slingshot
    ammo.

    Bob . . .
