Less fuel, less noise, less emissions, enhanced safety

The SafeRoute® suite of software applications uses Automatic Dependent Surveillance-Broadcast (ADS-B) technology to increase safety, efficiency and throughput for flight operators. Capabilities include In-Trail Procedures (ITP), CDTI Assisted Visual Separation (CAVS) and Surface Area Movement Management (SAMM). These functions offer a broad range of operational benefits, including fuel savings that result from flying more direct routes, as well as safety that comes from a moving map display with own-ship and traffic position in the air and on the ground.

In-Trail Procedures (ITP)

With SafeRoute ITP, operators spend more time flying at optimum altitude and realize significant savings in time, fuel and emissions. The system uses ADS-B to improve situational awareness and enable flight crews to perform desired flight-level changes on a more frequent basis in oceanic or non-radar airspace.

CDTI Assisted Visual Separation (CAVS)

CAVS is an important safety enhancement that allows the flight crew to continue a visual approach procedure using the electronic display to maintain separation if visual contact with traffic-to-follow is lost due to marginal visibility conditions. The electronic information displayed to the crew contains data about the aircraft they are following, such as ground speed, altitude and closure rate with the traffic. The flight crew can use that information to properly time the deceleration to final approach speed, configure for landing and avoid overtakes and go-arounds.

Surface Area Movement Management (SAMM)

More than 1,500 runway incursions have occurred at controlled airports in the U.S. in just the past few years. The SAMM application aims at dramatically reducing that number by providing a moving map display of the airport surface in the cockpit, showing own-ship and traffic operating in the terminal, taxi and runway areas. The SAMM module uses ADS-B and Traffic Information Service-Broadcast (TIS-B) to track vehicles operating in the operator’s area.


Operating Systems & Display Options SafeRoute applications can be hosted on an ACSS computer,
such as the TCAS 3000SP™ or T3CAS®.
ADS-B Out Transponders and NextGen Operations ACSS is leading aviation towards broader implementation of
NextGen/SESAR capabilities by developing ADS-B avionics.
ADS-B is the transmission of an aircraft’s position, speed and
intent to other aircraft and to Air Traffic Control. ACSS Mode S Transponders are certified to DO-260B,
the highest level of ADS-B Out, and are available now to meet the 2020 ADS-B mandates.
