Will SkyEcho software be updated to detect Mode C Transponders?

uAvionix has decided to not use Mode C because it cannot deliver adequate performance : SkyEcho has an omnidirectional antenna- hence no azimuth detection is possible The use of signal strength is unreliable as a distance measure Mode C transponders don’t transmit unless triggered by a ground radar or TCAS.  This doesn’t happen in many [...]


How the Beacons will operate

CAA have specified that the Beacons will broadcast 978MHz UAT ADS-B messages with an Emitter Category of ‘Point Obstacle’. The location broadcast by the Beacon will be based on the geographical position of the Beacon as reported by the Beacon’s built-in GNSS position source. The altitude broadcast will be a fixed altitude in feet above [...]


Receiving the Beacon Broadcasts

Airspace users equipped with 978MHz UAT ADS-B IN and within range of these broadcasts should be able to receive real-time alerting of site activity from the ADS-B Obstruction Beacon if their avionics/Electronic Flight Bag application receives 978MHz UAT ADS-B IN data and supports the display of 978Mhz UAT ADS-B Point Obstacles. Some avionics/Electronic Flight Bag [...]


CAA Guidance to GA Pilots

CAA has provided the following guidance for GA pilots: “Pilots observing the electronic depiction of an ADS-B Obstruction Beacon during the trial, should recognise that associated flying activities are underway, assess the location and vertical extent of the activity, avoiding the immediate vicinity of the beacon in accordance with their avoidance techniques when observing the [...]


Can ATC “see” my SkyEcho?

The prime objective of SkyEcho is air-air surveillance. However, the CASA AC envisages SkyEcho being used for situational awareness. In Australia, it is envisaged that Airservices Australia will, in due course, enable the display of SkyEcho with a different symbology for the purposes of ATC situational awareness. Different symbology is required so that the ATC [...]


Technical Characteristics of the Beacon’s 978MHz UAT ADS-B Messages

Address Qualifier Field Encoding In accordance with DO-282, Beacons will broadcast an Address Qualifier value of 5, meaning the Address Type is ‘Fixed ADS-B Beacon’, using a non-ICAO, state assigned unique 24-bit address. 24-bit Address Field As qualified by the above, each Beacon will broadcast a fixed non-ICAO 24- bit address (Hex Code). These will [...]


What is the design objective of SkyEcho?

The objective of SkyEcho was initially to meet the United Kingdom Conspicuity device market. See https://www.caa.co.uk/General-aviation/Aircraft-ownership-and-maintenance/Electronic-Conspicuity-devices/ The UK CAA says “To reduce the safety risk of airborne conflict between GA in uncontrolled UK airspace we have developed a minimum technical specification for low power, lightweight, portable Electronic Conspicuity Devices that operates using ADS-B.” In the [...]


Will tailBeaconX work with my existing transponder?

tailBeaconX is a replacement for your existing transponder.  tailBeaconX meets the requirements for use in all Mode A/C/S transponder required airspace as well as airspace requiring ADS-B Out.  If you are looking for a retrofit solution to work alongside your existing transponder you might be interested in the original tailBeacon.  Note tailBeacon approval is limited [...]


FAQ for the 978MHz UAT ADS-B Obstruction Beacon Trial

Why is this Obstruction Beacon trial being undertaken? The CAA’s Airspace Modernisation Strategy (AMS) outlines a range of new digital flight information services, including FIS-B and TIS-B (Flight Information Service – Broadcast and Traffic Information Service – Broadcast). ADS-B Obstruction Beacons are another element of these digital flight information services. Several GA representative organisations have [...]


What does the installation look like?

Although a little more involved than a standard tailBeacon, the tailBeaconX installation is still much simpler than comparable equipment. The tailBeaconX replaces the rear position light on the tail of the aircraft using the existing power and ground wires. The tailBeaconX does require a serial connection to a control head on the panel of the [...]
