NLR has tested a new software developed by CASRI for the detection and alerting of conflicts on taxiways and on the apron (Taxiway Conflict and Area Intrusion Detection).

CASRI is the Second Research Institute of the Civil Aviation Authorities of China (CAAC), and provides CNS and ATC products to Chinese Air Traffic Control (ATMB).

It also offers airport systems such as cockpit systems, taxiway and runway lighting systems and multi-lateration systems, baggage and security systems, and fuel management systems and information.

Operating in the Chinese aerospace industry, CASRI’s corporate office is located in Chengdu, a major city in Western China.

Since 2014, NLR has been engaged with CASRI. The following year, a first series of software verification tests were conducted for a Runway Incursion Alerting (RIA) controller tool, which was developed by CASRI. RIA controller tool is a software that warns air traffic controllers of potential conflicts on and around the runways.

The key reason for CASRI to select NLR as partner for conducting software testing was the experience that NLR has in developing different kinds of airport safety net algorithms. Furthermore, NLR is the developer and owner of NARSIM, the NLR ATC Research Simulator.

NARSIM enables realistic and flexible simulation of air traffic for system testing.

Following the successful tests conducted in 2015, the tests were performed this year in order to authenticate a software prototype of CASRI for detecting taxiway conflict and area intrusions at Chinese airports.

More than 90 realistic traffic scenarios were set up on the NARSIM-Tower platform for testing.

A fully re-worked touchscreen interface was used for the NARSIM pseudo-pilot position to enable initial set up and quick adaptation of the different traffic environments.
