Total number of positions in the last 30 days on 1090 Mhz equals 40,278,138,192 and on UAT 6,000,664. Let's divide the first number by 100 to assume that most of those positions are at higher altitude and only 1% at altitude relevant to us. So it is 6,000,664/402,781,381 * 100 = 1.489% As you see you are not missing much, unless you are in a special place near a large flight school that decided to install UATs. I don't see many UAT aircraft in the North East, but I agree it would be nice to have support for UAT. Where are you getting these statistics? I have a FlightAware ADS-B receiver at my cabin in Western WI. About 25% of the GA aircraft that fly over my cabin do not show up on my ADS-B receiver, which is 1090ES only. I suspect that most of these aircraft are UAT equipped. Flightaware.com To be more precise FlightAware ADS-B Statistics https://flightaware.com/adsb/stats/ Select top countries and the first entry is USA with the data I gave you. That is totally misleading. What you are looking at is the number of aircraft seen by FlightAware. There are almost no FlightAware receivers in the US that are configured to receive UAT ADS-B OUT transmissions. The VAST majority of FlightAware receivers are 1090ES only. The only reliable way to determine the 1090ES vs UAT equipage is to get this data from the FAA. They have all of this data, given that everyone equipped with ADS-B has to run an ADS-B performance report, which requires the pilot to identify not only what frequency the ADS-B OUT is on, but also the manufacturer of the ADS-B transmitter and GPS source. When you look at the low cost UAT ADS-B options available from Garmin, uAvionix, and others, I would be willing to wager that a very significant proportion of the GA fleet is UAT equipped. Well, I went back to look at configuration of some stations. It is true, many don't support UAT, so we simply don't know what the true number might be.. |

Since all aircraft that operate above 18K ft need to be 1090ES equipped, the percentage of single engine piston A/C that are potential threats to gliders is even higher than that. |

From Flarm on FCC approval. The device is FCC certified, we are just waiting for the paperwork, but all tests are done. I will not ship before we have the paperwork, should take 2-3 weeks.

There are about about 8000 commercial aircraft. That suggests about 120,000 GA aircraft are ADS-B equipped. There are about 220,000 GA aircraft registered in the US, suggesting 100,000 are not equipped with ADS-B. If true, our biggest danger is that 100,000, not the UAT equipped ones. It may not be that bad, as Flarm will pick up any of those with transponders. -- Eric Greenwell - Washington State, USA (change ".netto" to ".us" to email me) - "A Guide to Self-Launching Sailplane Operation" https://sites.google.com/site/motorg...ad-the-guide-1 |

ADS-R and TIS-B should be available very soon in all powerflarm units via firmware upgrade. I am flying with a beta version and can now see virtually all traffic, including UAT and mode C (via ground station relay). Stay tuned.

However, people need to understand that this is not the ideal solution vs. a dual band receiver: 1. You need to be within range of an ADS-B ground station, 2. The other aircraft needs to be at sufficient altitude to be visible to ATC Radar and/or an ADS-B ground station, and 3. Your glider needs to be ADS-B OUT equipped to trigger the ADS-B ground station to send you the ADS-R and TIS-B information. |

Yes, I overlooked the fact that you need ADSB out for this feature to work. So one more reason to hurry up and install ADS-B out in your glider.

All that is needed is for any 1090 out aircraft to be in the ADS range ie in the Puck to trigger the ground station for rebroadcast ADS-R. Richard |

An ADS-B OUT equipped aircraft that is in your vicinity will trigger the ground station to transmit ADS-R and TIS-B, but this will only occur on the frequency of the ADS-B OUT aircraft's IN receiver frequency. If you are near an aircraft configured with both a UAT transmitter and receiver, the ADS-R and TIS-B traffic will only be transmitted on the UAT frequency. The same situation occurs for a 1090ES OUT equipped aircraft that has a UAT receiver. |
