SkyEcho2 FAQ: Answers for the Sky-Curious Aviator

1. What does "portable" mean with regards to the SkyEcho 2?

   The SkyEcho 2 is a portable device, meaning you can carry it from aircraft to aircraft. It does not require physical or electrical installation into the airframe. As an EC device, it uses a 24-bit address in the same way as a transponder. You can program this address as it's designed to be used by unregistered aircraft as well. For further instructions on programming the 24-bit address, refer to the "How to use 24-bit addresses with Electronic Conspicuity Devices" section available on the Electronic Conspicuity page.

2. What kind of range does SkyEcho 2 have?

   The SkyEcho 2 is both an ADS-B IN (receive) and ADS-B OUT device. 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).

3. What frequency does it use?

   The ADS-B standard frequency for most of the world (excluding the U.S.) is 1090Mhz. SkyEcho transmits and receives on this frequency.

4. Can I see other aircraft with SkyEcho 2?

   Absolutely! SkyEcho 2's built-in Wi-Fi hotspot allows you to connect and display nearby traffic on a compatible app. SkyEcho uses a common interface format called GDL 90. Compatible apps include SkyDemon, Foreflight, Easy VFR, AirMate, Avare, Naviator, iFly 740, and FltPlan Go.

5. Can other aircraft see me?

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

6. Can ATC see me?

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

7. What are the limitations?

   EC systems are designed for aircraft to aircraft visibility, and an EC device will not meet standards to allow you to enter controlled airspace. The SkyEcho configuration app lets you turn off the transmit function while still being able to receive traffic for display on a compatible app if you already have a Mode S Transponder transmitting ADS-B OUT. According to AIC Y 141/2019, EC devices like SkyEcho 2 can be used simultaneously with a traditional ADS-B OUT Mode S Transponder. Before beginning simultaneous transmissions, the CAA requests notification as per Note 2 within AIC Y 141/2019.

8. Does it have an app? How do I view nearby air traffic in my cockpit?

   The echo iOS app is a configuration app for adjusting device settings, including setting the ICAO address and enabling/disabling the transmit function. For traffic display or moving map functionality, you will need to pair SkyEcho 2 with a compatible application like SkyDemon or your preferred EFB.

9. Do I have to reconfigure it if I move to a different aircraft? How?

   If you move between aircraft of similar size and type, you generally won't need to change anything. However, SkyEcho 2 does have configuration fields for different types of aircraft (light, glider, rotorcraft, etc.) and for aircraft size that might need adjusting. 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).
