- 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 UK, the output of SkyEcho is not normally provided to ATC. The idea is clearly focussed on air-air surveillance.
- SkyEcho was authorized to operate in Australia after CASA published changes t CAO 20:18 in mid-2020. CASA also published guidance in AC 91-23 (https://www.casa.gov.au/
sites/default/files/advisory- circular-91-23-ads-b- enhancing-situational- awareness.pdf) which notes ATC situational awareness with EC devices like SkyEcho.
