Air Evac EMS, which operates Air Evac Lifeteam and Texas LifeStar, have selected Becker Avionics’ 160mm BXP6403 Mode S Transponder (Class I) for installation on its EMS aircraft. The BXP6403 helps Air Evac to meet the future requirements of transponder technology by enhancing safety and situational awareness through the use of traffic information. The BXP6403 is a compact and lightweight single block Mode-S transponder. It is compatible with existing Mode A/C systems and provides the addition of data-link technology. The data-link provides flight critical information such as traffic which increases situational awareness while reducing the need for additional traffic detection equipment. Furthermore, the BXP6403 reports additional aircraft specific details to ATC providing a clearer picture of the flight environment. Air Evac selected the BXP6403 as a straightforward retrofit solution for the Bendix-King KT76A transponders currently installed in their aircraft. The BXP6403 Mode S Transponder is equipped with extended squitter and SI code function and it provides an interface to the central aircraft data system. It allows ELS, supports EHS, as well as ADS-B via extended squitter.
