Currently, SafeRoute+ offers five applications that increase traffic situational awareness, reduce missed approaches, enable higher achievable runway throughput, optimize spacing buffers, and reduce fuel burn, therefore lowering carbon emissions.

These applications are Enhanced Airborne Traffic Situational Awareness or AIRB, Interval Management Spacing (IMS),  CDTI Assisted Visual Separation (CAVS), In-Trail Procedures (ITP), Surface Area Movement Management (SAMM).

Operators can choose the applications which best align with their specific operations.


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.

Enhanced Airborne Traffic Situational Awareness or AIRB

AIRB provides the flight identification, altitude, speed, direction and wake category for aircraft up to 100 nautical miles away. This information creates an environment of shared situational awareness and aids the crew in visual acquisition of traffic. This is the basic application and does not require the additional AGD to be installed.

Interval Management Spacing (IMS)

During the arrival phase of a flight, the Interval Management Spacing (IMS) application maintains time-based spacing during instrument meteorological conditions, enabling flight crews to maintain consistent and well-spaced arrival flow to an airport. IMS reduces the distance and time flown, lowers the probability of vectoring and reduces low-variance aircraft Inter-Arrival Time (IAT). These key features enable block time predictability and maximizes runway capacity.

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.
