echoESX EXP

Expanding the Connected Cockpit

echoESX complements the uAvionix ecosystem, integrating seamlessly with AV-20-E, AV-30 (E/C), AV-HSI, AV-APA, AV-Link, and the ForeFlight Sentry ADS-B IN products. This ensures enhanced interoperability, providing pilots with intuitive control, enhanced situational awareness, and reduced complexity during cockpit retrofits.

Replace heavy transponders and blind encoders with a sleek, modern unit, reducing avionics weight for improved efficiency and performance.  Remove weight from your panel with uAvionix and remember – every 6 pounds saved from your panel = 1 gallon of gas!

Simplified Installation

Designed for quick and hassle-free installation, significantly reducing labor time and costs compared to traditional ADS-B Mode S transponders, echoESX is an easy replacement for your existing Mode C transponder with the ability to use your existing installed monopole transponder antenna.

Compact, lightweight, and power-efficient, the echoESX minimizes Size, Weight, and Power (SWaP), making it an ideal replacement for traditional transponders. The integrated GPS receiver removes the need and cost for a separate GPS installation.  An optional TSO certified GPS antenna from uAvionix provides the complete kit required.

uAvionix pioneered the use of micro SWaP electronics to enable ADS-B compliance through its tailBeacon, skyBeacon, and tailBeaconX products.  echoESX continues that tradition and provides incredible flexibility on fitment and mounting location, greatly expanding the number of compatible aircraft inlcuding fixed wing, gliders, and gyros.

Instant Setup and Configuration

Mechanically installing echoESX is the first easy step. Configuration is a breeze – integration with the AV-30 (and AV-20-E for Experimental Aircraft) quickly enables the setting of the necessary values including the ICAO address, emitter type, aircraft length, width and GPS offsets.
