"A challenge that the manufacturers have had to contend with is the fact that the ADS-B Out standard has been modified three times between 2010 and 2014. In early 2015, L-3 announced the Lynx line of ADS-B products for General Aviation (GA) that deliver compliance to the 2020 mandate and feature upgradability to add new features in the future. "The Lynx product line was designed to answer the needs of GA aircraft and pilots, whether they only need compliance to the mandate, or if they are looking to upgrade their cockpit with additional capabilities," says Oldach. L-3's Lynx NGT-9000 is a single box solution for ADS-B traffic, a Mode S Extended Squitter transponder with a compliant GPS/WAAS position source. The touchscreen display shows ADS-B traffic, weather information and moving maps.

A major concern of Greg Francois, senior technical sales manager for Honeywell Aerospace's Air Transport and Regional business, is that customers won't move forward to get wiring modifications done ahead of time. "I am really worried that everyone is going to wait until the last minute," he says. Francois says for air transport operators with older transponders, Honeywell is doing a whole unit swap with the new DO-260B transponder that comes with a five-year warranty. It doesn't include a GPS source, so Honeywell is offering two methods to replace the GPS: For older aircraft, Boeing is currently certifying the TRA-100B, Honeywell's latest DO-260B ADS-B Out compliant transponder that meets global requirements; for modern aircraft that have an existing multi-mode receiver, Honeywell is certifying their integrated MMR (or i-MMR) that is fully WAAS-enabled. Southwest Airlines is the launch customer for i-MMR, which it will deploy on its Boeing 737 MAX aircraft and its existing fleet of Boeing 737NG aircraft."

As these units are not backwards compatible, will the ADSB requirement in AUS change?
