5.1 International environments
5.1.1 United Kingdom
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.
5.1.2 Australia
In Australia, EC devices are intended for voluntary fitment on registered
and non-registered aircraft conducting VFR operations. They are not
permitted for IFR operations.
The fitment is not a substitute for mandatory carriage of a transponder nor
mandatory ADS-B in relevant airspace. In addition, they must not be
allowed to transmit when
(a) in VFR flight at or above FL290; or
(b) concurrently with a Mode S transponder that is also transmitting
ADS‑B. An EC device may be operated in Australia concurrently with a
Mode A/C, or a Mode S transponder (other than one that is transmitting
ADS-B).UAT is NOT used nor permitted in Australia

5.3.2 CASA CAO 20.18 Statement of Compliance.
An EC device must have a statement of compliance from the EC device
manufacturer certifying that the device meets the requirements 1 to 5 of
CAO20:18 Part B Appendix XIV 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 and that the declaration is carried on
board.
SkyEcho meets the requirements of 1 to 5 of CAO20:18 Part B Appendix
XIV. Since SkyEcho contains an internal pressure altitude sensor, if used
within a pressurized cockpit, the transmitted pressure altitude may be
erroneous and may not comply with CASA standards and deviation
requirements. For this reason, SkyEcho should be used only in
unpressurized aircraft when the transmit function is enabled.
