5 International Use Limitations
At the time of publishing of this revision, portable ADS-B OUT transmitters
are not permitted for global use (including the United States). Operating
SkyEcho outside of approved airspace, the transmit function must be
disabled. SkyEcho can be used as a receiver in all locations.
6 United Kingdom Regulation
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. EC Devices do not replace the
need for a transponder when required by airspace/flight rules. Aeronautical
Information Circular (AIC) Y 141/2019 allows for the use of EC devices
simultaneously with ATCRBS or Mode S transponders which are not
Extended Squitter (ES) or ADS-B OUT enabled. If your aircraft is ADS-B
OUT enabled, you must disable the transmit function of SkyEcho from the
configuration settings.
6.1 CAA CAP 1391 Declaration
An EC device that operates using ADS-B at 1090MHz must have a
Declaration of Capability and Conformance (DoCC) from the manufacturer
before you can legally use it on board an aircraft. The pilot in command of
the aircraft is responsible for ensuring that the EC device has a valid
declaration. Please refer to the CAA EC Web page for more information:

6.2 Mode-S or ATCRBS Limitations
EC Devices do not replace the need for a transponder when required by
airspace/flight rules. Aeronautical Information Circular (AIC) Y 141/2019
allows for the use of EC devices simultaneously with ATCRBS or Mode S
transponders which are not Extended Squitter (ES) or ADS-B OUT
enabled. If your aircraft is ADS-B OUT enabled, you must disable the
transmit function of SkyEcho from the configuration settings. Receive
functionality may still be used. Deactivation of the transmitter is
accomplished by removing device power or disabling the transmit capability
via the configuration settings. These regulations are subject to change.
Please be informed of the most current regulations at:

Conspicuity-devices/
6.3 Declaration of Conformity (DoC)
uAvionix Corporation declares that that the SkyEcho 2 ADS-B Transceiver
conforms with with the pertaining EU harmonization legislation and, since
31 January 2020, appropriate UK equivalents where applicable. Reference
the following standards which are applied:
•EN 62368-1:2014
•EN 62311:2008

Description of accessories and components, which allow the radio
equipment to operate as intended and covered by the DoC: SkyEcho 2 to
be used in conjunction with tablet running EFB APP like SkyDemon,
EasyVFR, Foreflight Mobile, and others.
6.4 Country Specific Configuration Items
The following configuration items augment the configuration instructions
found in the SkyEcho Installation and Pilot’s Guide with UK specific
information.
6.4.1 Transmit Control
Transmission must be deactivated when used on an aircraft with an air
traffic control radar beacon system (ATCRBS) Mode-S transponder which
has ADS-B OUT enabled.
6.4.2 Receiver Mode
The SkyEcho contains dual receivers. The primary receiver is permanently
configured for 1090MHz ADS-B. The secondary receiver can be
configured for either 978MHz UAT ADS-B, or 868.4MHz FLARM®
reception (European frequency only). Only one option can be selected.
When selecting UAT, SkyEcho will be able to receive 978MHz UAT ADS-B
weather and traffic information if available.
When selecting FLARM, encrypted FLARM data is received and
transmitted to the EFB application for processing. Specific FLARM
functionality is dependent upon the EFB functionality implemented.
6.4.3 Aircraft Address Programming (ICAO Address)
The ICAO address is a 24-bit number issued to the aircraft by the
registration authority of the aircraft. These addresses are usually written as
a 6-digit hexadecimal number, although you may also encounter one

UAV-1006630-00
ECCN 7A994 Page 10 | 10
REV A
written as an 8-digit octal number. The SkyEcho understands the
hexadecimal format, so you must first convert an octal number to
hexadecimal before entering. Sometimes this value is referred to as Mode
S code. It is critical that the correct address is used. Incorrect addresses
can disturb the service to other airspace users and may have regulatory
compliance consequences. In the UK to find the ICAO address of the
aircraft you will be flying go to https://siteapps.caa.co.uk/g-info/
Refer to UK CAA guidance for using 24-bit addresses with EC devices at
the following URL:
https://www.caa.co.uk/General-aviation/Aircraft-ownership-and-
maintenance/Electronic-Conspicuity-devices/
6.4.4 Call Sign
This is a maximum 8 character code that corresponds to the tail number of
the aircraft. (0-9, A-Z). The value should be entered without dashes: G-
ABCD should be entered as GABCD.
6.4.5 Emitter Category
To assist ATC tracking of aircraft, an aircraft category is transmitted. Select
the aircraft category that most closely matches the aircraft.
Note EC devices are not approved for all emitter categories. EC devices
are intended for voluntary carriage on registered and non-registered UK
Annex II aircraft, non-complex EASA aircraft of <5700kg MTOM, Permit
aircraft, and for gliders and balloons (including those covered under ELA 1
and ELA 2) within uncontrolled UK airspace.
