ALS features a unique concept of parametrisation which makes this solution easily adaptable to your specific operational needs. Our team of ATC experts is ready to tailor the system according to your local situation and habits and with aim to maximize comfort for your ATCOs.

User Features

All data (radar and non-radar) accessible from both Controllers’ positions

Both air traffic controllers (ATCOs) – Executive Controller (EC) and Planning Controller (PLC) can access the same functionalities.This results in better substitutability and operational safety.

Degradation resistant CWS

Controll Workstation (CWS) takes over a number of server functionalities, which makes CWS more independent. This allows CWS to operate also in case of server inaccessibility.

Comprehenssive position information

ALS provides a well organized and visually distinctive display of position information of all types (flight plan, ADS‑C, radar tracking). This feature heads toward a fully stripless system

Seamless Controller-Pilot and Controller-Controller communication

Controller-pilot data link communication (CPDLC) is integrated into ALS system and can be controlled by ATCO from CWS HMI. SYSCO is offered as a part of on-line data interchange (OLDI).

Wide range of non-radar data presentation options

Presentation of non-radar data can be adjusted (paper, strips, glass, electronic) and customized according to your local settings. All electronic strip data are editable and ready to be shared.

Safety Nets, Monitoring Aids and MTCD

These warning modules are offered as an integral part of ALS with expert setting and fine-tuning assistance.

Easy adjustments due to high level of parameterization

ALS can be easily tailored to ATCO specific needs, such as HMI colors and control, e-strip layout, strip posting rules, Safety Nets etc.

Billing and Statistics module

Adjustable in accordance with your local billing rules.

Data Security

In case of CWS failure, key data and functions are available at Supervisor’s position.

Record and replay feature

ALS allows to record and replay all operational data including audio communication. Record can be used for the evaluation of emergency situation.


  • Software development strictly follows ISO/IEC 12207
  • Functional Hazard Assessment is used for the system design
  • PSSA is a part of ALS product

HW redundancy and seamless switching

ALS has been developed with regard to performance redundancy and full hardware redundancy. ALS switching feature guarantees uninterrupted system operation

Advanced CWS sectorization

ALS operates with the feature of quick and safe sector redistribution in case of CWS outage. The sectors of any CWS can be seamlessly transferred to any other CWS.

Technical Features

Open architecture
ALS’s open architecture allows tailor-made solutions which may be gradually developed and changed according to your operating needs.

Distributed system
ALS deploys distributed computing between the core and applied modules which makes the whole system more degradation resistant. For example, CWS takes over a number of server functionalities and consequently reduces the load of its operations.

Reliability and Robustness
High availability and reliability of the system is supported by hardware redundancy and quick software switching.

Customizable AIS module
All necessary data for Flight Information Service (AIS, MET, warning frequencies, etc.) can be displayed on a separate screen or in a window on CWS display (depending on custom settings).

Surveillance data flexibility
Module Tracker processes radar, passive radar and ADS-C data. The most accurate data available are chosen for position computing. In case of an absence of surveillance data (in areas with no radar coverage), the CWS screen displays Flight Plan Tracks computed by FDPS.

Easy setting of interoperability
Interoperability is defined in custom “Data Set”, meaning it can be quickly adapted to local coordination adjusting and transfer conditions.

Sophisticated two-way AFTN module
The AFTN Daemon does not only process AFTN messages, but enables you to compile and distribute all kinds of AFTN messages as well.

Comprehensive monitoring and control
The Monitoring module is an integral part of the whole system. It continuously generates the overview of the status and possible errors of individual ALS components. Early warnings enable to eliminate significant malfunctions.

OLDI complying with Eurocontrol standard
The module is an integral part of ALS and is adjustable to your local needs. It can be deactivated.

Progressive 4D Trajectory Prediction
ALS features cutting-edge functionalities. 4D Trajectory Prediction is driven by advanced route extraction operating within Area of Interest. The ETO and altitude computation is enhanced by radar updates and the results are based on complex computations using precise aircraft performance parameters. This results in an exact altitude prediction.

Datalink for uncovered areas
ALS is able to use Datalink functionalities (such as CPDLC and ADS-C) for oceanic sectors or areas without radar and radio coverage.
