Area LETVIS® ATM system is designed for the planning, procedural and/or radar control of air traffic at any level of air traffic services provided by Area Control Centre for civil, military or joint operation. Controllers are provided with the integrated air picture of civil/military air traffic including information on structure and utilization of airspace, and other supplementary data/support capabilities.

Area LETVIS® ATM system can be delivered in a variety of customer-specified configurations, ranging from working positions/modules to comprehensive ATM systems that along with other sub-systems and equipment (voice communication systems, radar systems, consoles & cabinets, etc.) allow for a modernization of existing ACCs or a supply of new ACCs as turn-key solutions.

The system provides all ATM capabilities at ACCs to the full extent while enabling:
- Planning and control of military air traffic acc. to ICAO and/or national military procedures
- Planning and control of civil air traffic acc. to ICAO and/or national standards (GOST, FAA, etc.)
- Joint (under EUROCONTROL) planning and control of civil/military air traffic
- Other related activities or processes (related to data recording & analysis, data exchange with other ATM centres, training, etc.)
Both general and extended capabilities of Area ATM System are covered by LETVIS® modules. Data processed by LETVIS® modules can be presented on single or multi-screen display of up to 2Kx2K resolution.
