LETVIS SIM system – is designed to simulate a wide range of civil and military ATM environment. The system fully substitutes real ATM data processing and the simulated air traffic situation is displayed at the Controller (Student) WPs.

- Student WP(s) - includes Controller Positions and Assistant Positions for Executive Controller and Planner respectively
- Airspace and Scenario Development WP incl. Pseudo-Pilot Position and Instructor/Supervisor Position.
This HW + SW configuration, when integrated with such equipment as voice communication system (intercom basis), recording & replay system, etc. is capable of reliable ATC operator training. ATC Simulator is delivered as custom-tailored turn-key solution incl. related support equipment and services (consoles/cabinets, cabling, etc.).

A core of LETVIS SIM system represents Generator of Radar Data (SIM/GEN) and Generator of FPL Data (SIM/FDS). The core system enables to generate data matching, physically and logically, with those of real operational sources. Student WPs are, at the same time, running in operational mode what enables a simulation of any air traffic situation that can occur in real environment.
SIM/GEN output is fully controlled by Instructor who is provided with a capability to modify the exercise characteristics in order to train the system degradation through radar switching-off or output data quality reducing. This SIM/GEN functionality enables to test the systems of multi-radar data processing, as well. SIM/GEN is capable of generating the raw-video output of a selected PSR or PAR incl. radar jamming simulation.

Simulation of special events such as
o Emergency state
o Change of SSR Code or Mode
o Aircraft equipment malfunctions
o Erroneous set up of QNH
o Target indication by airborne radar for target tracking
o Afterburning switch on/off
Procedures of aircraft manoeuvres
o Automatic SID / STAR procedures
o Automatic instrumental landing system
o Holding procedures
o Alternate route entry
o Missed approach
o Circuit pattern
