Electronic Conspicuity

SkyEcho is a portable ADS-B IN/OUT transceiver consistent with the UK CAA’s Electronic Conspicuity standard.  SkyEcho transmits your aircraft position, altitude, course and speed to surrounding aircraft to improve awareness. SkyEcho also includes a dual-band ADS-B receiver to receive position reports from other ADS-B equipped aircraft and display them on in-flight applications, including ForeFlight Mobile, SkyDemon, and EasyVFR.

Ready for the Future

The United Kingdom is testing and implementing in-flight weather and other services over UAT (978MHz).  SkyEcho comes ready for the future with a built in 978MHz ADS-B receiver so you can benefit from this new service.

SkyEcho receives in-flight weather from UAT ground stations. Weather data includes radar, winds METARS, TAFs and more.

UAT in the UK, Part II

uAvionix has deployed two more UAT ground stations in the UK delivering inflight weather for pilots.

UAT in the UK, Part I

The UK has officially announced that ADS-B is the “preferred national system for electronic conspicuity."

Cooperative Skies

CAP-1391 allows light aircraft, gliders and balloons to see and be seen by other aircraft without equipping a traditional transponder.  SkyEcho is approved for use in:


SkyEcho at a Glance

  • 20W nominal 1090ES transmitter (1090 MHz) for use in the United Kingdom

  • 1090ES reception (1090 MHz) from aircraft equipped with 1090 MHz Extended Squitter transmitters
  • Aviation Integrity SBAS and RAIM enabled TSO-C199 GPS provides position data for ADS-B Out transmissions

  • Traffic information from 1090ES are correlated to provide a coherent view of nearby aircraft
  • ADS-B 978Mhz receiver broadcasts traffic information over Wi-Fi to compatible flight applications and EFIS displays

  • Integrated rechargeable battery provides 12 hours of flight time

Extendable Awareness

SkyEcho is extendable to increase the level of cooperation by receiving additional information from other popular EC technologies.
In addition to FLARMbridge, additional expansion is planned for DroneAware.

Introducing FLARMbridge

FLARMbridge is the first in a series of expandable options for SkyEcho 2. With FLARMbridge you can easily and wirelessly connect your existing FLARM product installation in your aircraft to SkyEcho 2. SkyEcho 2 will translate the FLARM data onto your EFB along with the ADS-B traffic.

FLARMbridge will be available in January. Sign up for notifications here.

What’s Included

The SkyEcho 2 device easily fits in any backpack or flight bag. Included is the RAM® suction cup mount with quick release for installation and removal of SkyEcho 2 in under 1 second. Also Included is a USB-C cable for charging or direct power from your aircraft.

Have Questions?

Take a look at our frequently asked questions

Can I use SkyEcho in the U.S.2017-03-27T22:38:04-06:00

No.  The SkyEcho is currently approved for use as an ADS-B out device in the U.K. under the innovative CAP 1391 program.  Use of SkyEcho in the United States is prohibited by the FCC and FAA.

What is Electronic Conspicuity?2017-03-26T00:08:18-06:00

Electronic Conspicuity (EC) is an umbrella term for a range of technologies that, in their most basic form, transmit the position of the host aircraft to other airspace users operating compatible equipment. More advanced devices can also transmit and receive, displaying and alerting pilots to other/conflicting traffic who have compatible EC devices. EC devices turn the traditional ‘see and avoid’ concept into ‘see, BE SEEN, and avoid’.  You can learn more about the program on the UK CAA’s Electronic Conspicuity page.

EC devices are intended for voluntary carriage on registered and non-registered UK Annex II  aircraft, non-complex EASA aircraft of <5700kg MTOM and for gliders and balloons (including those covered under ELA 1 and ELA 2) within uncontrolled UK airspace.

An EC device cannot be used at the same time as a transponder and it doesn’t replace the need for a transponder when required by airspace/flight rules. If your aircraft is fitted with a working transponder, you must switch off the transmitter function of your EC device.  SkyEcho provides this functionality.

What does “portable” mean with regards to the SkyEcho?2017-03-26T00:12:34-06:00

The SkyEcho is a portable device that you can take with you from aircraft to aircraft and does not require physical or electrical installation into the airframe.  EC devices use a 24-bit address in the same way as a transponder.  This usually forms part of an aircraft’s Certificate of Registration.  However, as an EC device is designed to be portable and to also be used by unregistered aircraft, the 24-bit address will be programmable by the user.   The device is small enough to sit on your glare shield and fit easily in your flight bag.

Refer to the guidelines under the section titled “How to use 24-bit addresses with Electronic Conspicuity Devices” section available on the Electronic Conspicuity page.

What kind of range does SkyEcho have?2018-05-08T16:15:09-06:00

The SkyEcho is both an ADS-B IN (receive) and ADS-B OUT device.  Range is a function of transmit power. Depending on the output power of other aircraft, you will be able to SEE other aircraft over 270km (~150 NM) away.  SkyEcho has a transmit power of 25W on 1090MHz (1090ES).

What frequency does it use?2017-03-26T00:18:25-06:00

The ADS-B standard frequency for most of the world (all but the U.S.) is 1090Mhz.  In the U.S. 1090Mhz as well as 978Mhz is used.  SkyEcho transmits and receives on 1090Mhz.

Can I see other aircraft with SkyEcho?2017-03-26T00:19:56-06:00

Yes!  SkyEcho has built-in Wi-Fi hotspot that allows you to connect and display nearby traffic on a compatible app.  SkyEcho uses a common interface format called GDL 90.  As of now (Nov 2016), SkyDemon, Foreflight, Avare, Naviator, iFly 740 and FltPlan Go are a few of the compatible applications.  If you are a developer and would like to confirm compatibility please contact us.

Can other aircraft see me?2017-05-04T08:05:23-06:00

Yes.  Any aircraft equipped with ADS-B IN capability can see you.  This includes other EC devices as well as installed avionics, and other third party systems such as the Garmin GDL39, PilotAware and Flarm.

Can ATC see me?2017-03-26T00:28:29-06:00

Yes ATC can see you if you are transmitting within range of an ATC ADS-B ground station radio.

What are the limitations?2018-06-25T15:16:17-06:00

EC systems are designed for aircraft to aircraft visibility. An EC device will not meet standards to allow you to enter controlled airspace. Additionally, if you have an installed Mode S transponder in your aircraft, you will have to turn off the transmit function of the SkyEcho. This is standard for all EC devices and is designed to keep you from presenting a “double target” on ATC displays. The SkyEcho configuration app allows you to turn off the transmit function while still being able to receive traffic for display on the compatible app.

Does it have an app? How do I view nearby air traffic in my cockpit?2017-03-26T00:27:43-06:00

The echo iOS app is a configuration app that allows you to configure device settings, including setting the ICAO address and enabling/disabling the transmit function. The echo iOS app is not a moving map or traffic display app. For this functionality, you will need to pair with a compatible application such as SkyDemon or your preferred EFB.

Do I have to reconfigure it if I move to a different aircraft? How?2017-03-26T00:27:58-06:00

If you are moving from one aircraft to another of similar size and type, you should not have to change anything.  However other configuration fields exist for type of aircraft (light, glider, rotorcraft, etc.) as well as aircraft size, etc.  EC devices are intended for voluntary carriage on registered and non-registered UK Annex II  aircraft, non-complex EASA aircraft of <5700kg MTOM and for gliders and balloons (including those covered under ELA 1 and ELA 2).

Where is this going?2017-03-26T00:28:00-06:00

We hope worldwide!  Regulatory agencies are viewing EC devices as an affordable solution to increase the safety of national airspace systems by providing pilots with greater situational awareness.  The UK is the first, EASA soon to follow – from there – who knows?  As far as the product goes, we will plan our roadmap based on feedback from our customers and hope to deliver a more integrated product in the future.
