Germany’s Becker Avionics last month introduced a line of mode-S transponders capable of broadcasting ADS-B (automatic dependent surveillance-broadcast)-in and -out signals. The new BXP62XX and BXT62xx transponders, due to hit the market by year-end, will feature ADS-B-out capability. Follow-on models due out sometime next year will add ADS-B-in functionality. ADS-B-in lets pilots view flight information, including speed, altitude and intended track, of other airplanes in the vicinity.
