ACSS launches new flight deck retrofit solution for ADS-B in surveillance technology

New SafeRoute+™ Retrofit Solution Minimizes Installation Costs So Airlines Can Realize the Safety and Financial Benefits of ADS-B In

Le Bourget, France, June 17, 2019

ACSS, an L3 Technologies and Thales Company, has launched SafeRoute+™, an ADS-B In retrofit solution for airlines. This new design, including an all-new display, enables airlines to enhance safety and efficiency and improves on-time performance without extensive and costly cockpit modifications.

"Our new design is a significant advancement for the airline industry. It's the only retrofit cockpit surveillance system available for ADS-B In technology," said Terry Flaishans, President of ACSS, part of L3's Commercial Aviation sector. "The new ADS-B Guidance Display makes upgrades affordable and yields a much higher return on our customers' investment. Pilots like it because they can see all the information about surrounding aircraft, including speed and distance; airlines like it because it ensures efficiency and improves the time it takes to turn flights and maintain profitable schedules."

SafeRoute+'s ADS-B In applications are hosted on their TCAS 3000SP™ or T3CAS® computers and executed using the existing Navigation Display (ND) and Multi-function Control and Display Unit (MCDU), as well as the new ADS-B Guidance Display (AGD) from ACSS.

Pilots are finding SafeRoute+ easy to learn, and the new retrofit architecture makes it practical and economical for operators to start using ADS-B In applications in 2020. SafeRoute+ currently offers five applications, which increase situational awareness, reduce missed approaches, enable higher achievable throughput, optimize spacing buffers and reduce fuel burn, thereby lowering carbon emissions. Operators can choose the applications that best align with their specific operations.

The first generation of SafeRoute was certified using Class 3 Electronic Flight Bags (EFBs); the new SafeRoute+ architecture eliminates the need for these costly Class 3 EFB devices. SafeRoute+ is expected to be certified in the third quarter of this year.

SafeRoute+ provides an economical solution for airlines to take advantage of multiple ADS-B In functions starting in 2020, enabling operators to reduce costs, fuel burn and emissions while increasing situational awareness and airport efficiency and throughput.

SafeRoute+ Applications

The baseline application for SafeRoute+ is Enhanced Airborne Traffic Situational Awareness or AIRB. When surveyed, 84 percent of pilots reported that ADS-B In enhances their situational awareness, and 15 percent identified traffic ground speed as the most useful piece of information. AIRB provides the flight identification, altitude, ground speed, vertical speed, track angle 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.

The CDTI Assisted Visual Separation (CAVS) application aids flight crew in managing spacing that is more efficient during final approach during challenging visual conditions. CAVS can help reduce go-arounds, keeping flights running on time during reduced visibility conditions.

The Interval Management Spacing (IMS) application maintains time-based spacing during instrument meteorological conditions. IMS allows consistent low-variance aircraft Inter-Arrival Time (IAT) that enables block time predictability and maximizes runway capacity.

The In-Trail Procedures (ITP) application provides the flight crew with a vertical profile view of surrounding traffic over 100Nm away, which is useful during oceanic routes. The Federal Aviation Administration (FAA) has released studies reporting transatlantic ITP-equipped flights have saved an average of 670 pounds of fuel and likewise, transpacific flights have saved an average 521 pounds. This fuel savings also results in a significant reduction in carbon dioxide emissions.

The new AGD from ACSS is required to enable and interact with these advanced ADS-B In applications, specifically CAVS, IMS and ITP. SafeRoute+ surface applications will also soon be available to provide situational awareness and alerts to reduce the likelihood of runway incursions using a tablet.
