Diversity: Understanding that each individual is unique, and recognizing our individual differences

With 7.71 billion people on our planet it’s hard to imagine we are all unique, especially when you consider that everything in the universe came from one unimaginably small singularity—the Big Bang. Even so, most of us look, sound, and act differently than anyone else.

Automatic Dependent Surveillance-Broadcast (ADS-B) equipped aircraft are similarly unique, as each has an individual identification code derived from the aircraft’s registration number. This code is transmitted by each aircraft’s ADS-B device, along with position, altitude, speed, direction, and other data. This information is received, processed, and retransmitted by dedicated ground stations, allowing others to recognize and follow us wherever we go. The Citizen of the World will be tracked globally during her polar circumnavigation using ADS-B.

Matt Desch, the CEO of Iridium, explained that in order for the Citizen of the World to be tracked at all times during her world peace mission connecting the South Pole to the North Pole and everywhere in between, she will need “diversity.” Diversity is implemented by installing a second ADS-B transponder antenna on the top of the airplane in addition to the antenna installed on the bottom. This will allow her to be tracked over the oceans (and any other location where there are no ground stations) by the constellation of 66 Iridium NEXT low earth orbit satellites that came online earlier this year.

Allow me to nerd out for a brief second. Real-time flight data is sent from the ADS-B transponders to the Iridium NEXT satellites, and through a partnership with Aireon the data is sent to ground stations for use by air traffic control and other entities. This data is also used by our friends at FlightAware.com, a website where you type in an aircraft’s registration number and can track its altitude, speed and location. Iridium NEXT has made possible a “100 percent” global air traffic surveillance system that will increase safety, enhance efficiency, improve predictability, expand capacity, and lower costs. These benefits will, in turn, result in a significant reduction of carbon in the atmosphere—the equivalent of removing 300,000 cars a year from the roads. This is a true win-win situation.

To showcase this capability, the Citizen of the World will be the first aircraft to be tracked globally using ADS-B during a polar circumnavigation.

Now do I have your attention?

While this seems simple enough in concept, in practice it is not. Although very few transponders are currently capable of diversity, the Lynx NGT-9000 from L3 is. It’s a very compact, yet robust system that provides ADS-B Out functionality along with ADS-B In traffic and weather. It has a bright, high resolution touchscreen and also offers terrain avoidance and active traffic. The NGT-9000 is packaged as either a transponder-sized panel mounted instrument or a remotely mounted box. Amazing!

Canada will soon require that all aircraft operating in specified airspace have ADS-B Out with diversity. This will enable them to use Iridium NEXT for air traffic control without the expense and complexity of ground radar installations and the associated infrastructure. You can see the writing on the wall. It’s just a matter of time until every country on the planet requires this.

Adding diversity capability to the Citizen of the World will not be straightforward because the antenna installation must pass through the pressure vessel, requiring extensive documentation by an FAA Designated Engineering Representative. These documents will be then be submitted to the local FAA Flight Standards District Office for approval.

Acquiring the ADS-B diversity equipment and designing and documenting the installation are relatively easy. The hardest part these days is finding an avionics shop that has time for an installation. Most shops are already booked to the end of the year with aircraft trying to meet the January 1, 2020 FAA mandate for ADS-B Out.

Neil Aviation in San Diego installed the panel on my former airplane, the Spirit of San Diego, as well as the Avidyne panel on the Citizen of the World. The owner, Garrett Neal, has stepped up once again to help me with diversity. Garrett saw the importance of our mission of One Planet, One People, One Plane, and realizes that the Citizen will have very high visibility as it undertakes its unique journey. He went out of his way to make time for this project. For that, I am incredibly grateful.

Is there a downside to ADS-B In/Out besides the initial time, cost, and frustration to install? There is speculation that the data collected might one day lead to changes in how the airspace system operates but we’ll need to wait awhile and see.

With respect to being unique, there are certainly advantages and disadvantages for both airplanes and for people. Only time will tell if the benefits outweigh the costs.
