FAA Certifies SafeRoute+ ADS-B In Retrofit Solution on A321 Platform

Mar 11, 2020



  • Software and ADS-B Guidance Display (AGD) solution receives TSO certification
  • STC approval issued for SafeRoute+ installation on A321 aircraft 
  • Enhances safety and increases operational efficiency

ACSS, an L3Harris Technologies and Thales company, announced the certifications for the SafeRoute+ ADS-B In retrofit solution for airlines.

The FAA granted the Technical Standard Order (TSO) authorization for the SafeRoute+ software and the new ADS-B Guidance Display (AGD) sold by ACSS and developed by L3Harris. The STC has also been issued for SafeRoute+ software and hardware installation on the American Airlines A321 fleet.

These certifications are an important step in the ADS-B In Retrofit Spacing Evaluation program – AIRS. AIRS is a formal, collaborative effort between the FAA, American Airlines and ACSS to promote the early adoption of ADS-B In applications by fielding and evaluating a cost-effective retrofit solution.

“Airlines have spent a lot of money equipping their aircraft with ADS-B Out so that air traffic controllers have better aircraft data to route flights safely and more efficiently,” said Terry Flaishans, President of ACSS. “This program enabled us to work side-by-side with pilots and the FAA to develop a viable retrofit solution that enables airlines to take advantage of that same information; thereby enhancing safety, enabling better decision making and ultimately greater airport efficiency.”

Selectable SafeRoute+ ADS-B In applications hosted in the TCAS 3000SP or T3CAS® computers utilize the existing Navigation Displays (ND) and Multipurpose Control and Display Units (MCDU). Advanced applications require the installation of the newly developed AGD from L3Harris.

AIRS was launched under a memorandum of agreement signed in July 2016 to promote the early adoption of ADS-B In application by fielding a cost-effective retrofit solution that can be applied to a large percentage of the market for the operational evaluation of select ADS-B In applications.

“We have demonstrated the system with numerous pilots in our simulators, specifically to solicit feedback during the development phase to ensure it was easy to learn and use by the pilots,” said Chuck Manberg, Technical Fellow and Lead ADS-B engineer at ACSS. “The operational and human factors research was instrumental in making SafeRoute+ affordable and adoptable.”  

Installation has started on the A321 fleet with the newly certified SafeRoute+ solution. The AIRS program will evaluate specific ADS-B In applications by collecting operational data and performing benefit analysis for eventual reporting to the industry.
