product description

The Avidyne AXP340 Transponder is a panel-mounted Class 1 Mode-S Level 2 Datalink Transponder, with support for 1090 MHz 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 and GPS Lat/Lon readout, Flight ID entry, one-touch VFR code entry, an easy-to-use Stop Watch Timer, Flight Timer, and Altitude Alerter.

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).

The AXP340 delivers 240 Watts of transmitter power, and responds to both legacy Mode A/C interrogations and to Mode S interrogations from both ground radar and airborne collision avoidance systems. In the Mode-S environment (S stands for Select), a Mode-S interrogator can selectively address a single transponder. This allows accurate position plotting with lower reply rates, which in turn reduces frequency congestion and interference.

Coupled with any of Avidyne‘s TAS600A ADS-B capable Traffic Advisory Systems, the AXP340 provides full ADS-B surveillance capability to meet the upcoming mandates for flight internationally and above and below FL180 in the U.S. The AXP340 transmits the required ADS-B Out signals including your aircraft’s GPS-derived position, along with ground track, ground speed and altitude information. The TAS600A provides ADS-B In, allowing you to receive the ADS-B signals from ground radar and from other 1090 MHz ADS-B - equipped aircraft and display both ADS-B and non-ADS-B traffic simultaneously for optimal situational awareness and safety.
