Yes, echoESX meets the FAA ADS-B Out performance standards as per 14 CFR 91.227.
What does installation involve?
echoESX installs quickly using existing monopole transponder antennas and an integrated GPS, significantly reducing installation complexity and cost. External GPS Antenna is required.
How do pilots control and configure echoESX?
Control and configuration are handled seamlessly via AV-30-E or AV-20-E instruments, simplifying pilot interaction.
What routine maintenance is required?
