AXP340 Mode S Transponder
with ADS-B Out
Avidyne’s AXP340 Mode S Transponder provides an ADS-B Out solution for general aviation aircraft in a simple, easy-to-use, plug & play design.
AXP340 ADS-B Mode S Transponder
The AXP340 transponder is a panel-mounted Class 1 Mode S Level 2 Datalink
Transponder, with support for 1090MHz Extended Squitter (ES), that meets all the
current requirements for Mode S elementary surveillance transponders for both IFR
and VFR flight. As a slide-in replacement for existing KT76A/KT78A transponders, the AXP340 is designed to easily upgrade existing Mode A/C equipment to Mode S, while adding additional functionality like a Direct-entry Numeric Keypad, Pressure Altitude & GPS Lat/Lon readout, Flight ID entry, one-touch VFR code entry, an easy-to-use Stop Watch Timer, Flight Timer, and Altitude Alerter.
Meeting the Mandate for ADS-B
The AXP340 also supports the latest Version 2 1090 MHz Automatic Dependent
Surveillance Broadcast (ADS-B) Extended Squitter, known as “ADS-B out”. Equipping with ADS-B Out will be required in most U.S. airspace by 2020. The AXP340, when linked to a suitable GPS receiver, transmits position information to appropriately-equipped ground stations and other aircraft. This provides improved airborne surveillance,
provides vital information for airport ground surveillance, and is a key feature of future airspace plans.
The AXP340 provides an affordable and lightweight Mode S Surveillance and ADS-B Out solution for fixed wing and helicopter operators.
The AXP340 is a slide-in replacement for the venerable KT76A transponder, making it a great choice for upgrades, as well as for new installations. (Additional wiring required for ADS-B functionality.)
