    HeliStorm, my only point is that, unfortunately, ADS-B can't be a 100% solution to being being able to sense & avoid aircraft here in the US, as not all aircraft are, or will be, equipped with ADS-B transmitters.  That includes ultralight vehicles, which are not considered to be aircraft by the FAA.

    As for ultralights, they are more strictly regulated under Part 103 than most people realize.  In addition to weight limitations, they can't be operated "over any congested area of a city, town, or settlement, or over any open air assembly of persons", can't be operated at night, can't be operated in the types of airspace that cover many large urban areas, etc.  If the FAA were to apply similar regulations to UAVs, many of those who wish to use them commercially (except, perhaps, farmers) would be quite unhappy...

    Mind you, I don't want my friend to lose his ultra-light. Interestingly, he owns a farm, and claimed the ultra-light purchase was to aid in crop maintenance. He flies over his fields, and occasionally I think he has spotted some blight, but mostly he flies for fun-sake. He actually asked me once about using a UAV for similar use, as it would be cheaper to operate. When I told him technically that would be illegal, he was floored.

    Marc, to go along with your comment, ultra-light aircraft are allowed in the airspace with no positioning system required, and piloted by unlicensed amateurs. I have often wondered why the government is trying to strictly regulate, or even ban, my sub-pound camera quad, but a friend of mine gets to keep his ultra-light?

    Excellent!  A few cautions, though, for those of us in the US:

    • Not all (or even most) aircraft are currently equipped with ADS-B transmitters ("out").  The FAA won't be mandating use of ADS-B out for most aircraft until 2020, and even then some aircraft (like gliders and powered aircraft without electrical systems) will not be included in the mandate.
    • ADS-B uses two separate frequencies (and protocols) in the US, 1090Mhz (1090ES) and 978Mhz (UAT), so two receivers would be required for detecting all ADS-B equipped aircraft.
    • If an ADS-B ground station is in the area, it will retransmit traffic data (including that derived from radar targets) on 1090ES and/or UAT, but only if it detects there is a aircraft equipped with ADS-B out capability in the area.

    This sort of thing is a great help for situational awareness, but it can not replace visual lookout as a result of these limitations...

    Great work John! This technology will really help us to fly FPV more safely and will also help for us to keep it a legal activity.
