From this news article dated April 30, 2015: "As of today, Host is history," FAA Administrator Michael Huerta declared during a press conference. From the latest NextGen report dated June 2016: In March 2015, the 20 planned ERAM sites achieved operational readiness, which signified the full commissioning of ERAM into the NAS and allowed the FAA to ...


ADS-B UAT operates on 978 MHz and are available for aircraft that operate below 18,000 FT MSL. UAT transceivers can display aviation weather products (FIS-B) as well as traffic from ground radio stations (TIS-B). The airplane must be in a coverage area for TIS-B services. TIS-B is intended to provide ADS-B equipped aircraft with a more complete traffic ...


From*: The FAA wanted to implement Continuous Descent Approach (CDA) at La Guardia as part of the Regional Airspace Redesign to reduce the noise impact when they terminalized a much larger area. In the Draft Environmental Impact Study (DEIS) CDA was included however CDA failed the safety field test in the summer of 2007 and was not included ...


TIS-B is part of the ADS-B system that will be required in class B and C airspace come 2020. The processing of traffic relevant to your aircraft is done on the ground to keep the airwaves "clean" as it would require transmission of much more data to show all aircraft and then have your local device filter it. In order for you to take advantage of your own "...


No. ADS-B ES equipped aircraft do not have to have UAT to allow ADS-B UAT equipped aircraft to 'see' them. Below FL180, they are tracked by ATC radar and their track is translated and re-transmitted to UAT equipped aircraft via TIS-B service. More information, as well as coverage maps are available at the NextGen ADS-B site.


I was lucky enough to work a career that spanned all three systems:IBM 9020, IBM 3083 (HOST) and ERAM. HOST is no longer in use even as a backup. The backup system used to be a stand alone system called DARC (Direct Access Radar Channel). ERAM has a redundant channel of supposedly identical hardware and software as a "back up". This is problematic though. I ...


Actually, aircraft broadcasting ADS-B Out on one frequency (say 1090Mhz) and equipped with ADS-B In, will receive traffic operating ADS-B Out on the other frequency (in this example, 978Mhz) via the ADS-R (ADS-B Re-broadcast) service.


Here there is a list of possible meanings of this abbreviation. Most of the interpretations are completely reputable and legitimate but maybe "Crash-Damaged Aircraft" is both negative and aviation-related.


If the aircraft will be flown above 18,000ft or in other countries with an ADS-B mandate, 1090ES is required. This applies to pretty much all "large" aircraft; they have no choice. However, the US has an enormous light GA fleet with very vocal owners, and the FAA itself was concerned about 1090MHz congestion, so they added UAT (on 978MHz) as an alternative....
