More avionics manufacturers are trying to jump-start ADS-B installations for light aircraft by offering rebates in advance of the FAA’s own $500 rebate offer, which takes effect in September. Avidyne is offering a $500 rebate for orders placed through September 30 on purchases of $5,000 or more, and it is available for owners of single-engine piston-powered aircraft. Buyers can also combine the rebate with Avidyne’s promotional offer of a free SkyTrax100 ADS-B IN receiver when purchasing an IFD540 navigator with Wi-Fi and Bluetooth and an AXP340 mode-S transponder.

NavWorx appears to offer the lowest-cost ADS-B OUT and IN package with a $200 temporary price reduction for the ADS600-B UAT transceiver, bringing the price down to $1,799 until July 31. The ADS600-B includes a rule-compliant WAAS GPS sensor and it is STC approved for all certified aircraft, according to NavWorx, although it is limited to aircraft that fly below 18,000 feet. There is no need to install a separate control head with the ADS600-B as NavWorx has developed the TransMonSPE, which “allows you to keep your existing transponder and altitude encoder,” according to the company. A Wi-Fi adaptor for delivery of ADS-B information to mobile devices is an additional $149.
