AIRCON 2100 is a robust ATS system operating on Linux Red Hat Enterprise 5, comprising of dually redundant servers connected by a 3 LAN configuration. It integrates Surveillance data from multi radar inputs, ADS input, AFTN data from AMSS ECIL servers or data generated within the system via manual input at controller work position or stored RPL data. Two LANs provide redundancy whereas the third LAN acts as a bypass to provide raw radar data feed to the control work position in case of failure of surveillance data proces

AIRCON 2100 comprises of Radar Data Compression Unit (RDCU), Flight Data Processor (FDP), Situation Data Processor (SDP), Safety Net (SNET), Data Recording Facility and Voice Recorder. Each of these has dual redundancy. The system has single RDCU Transmission unit. A Common Timing Facility (CTF) receives the GPS time, feeds to all the subsystems and synchronizes all clocks.
19.1.2 The system supports two controller work positions (CWP) for ACC and two CWP for APP positions, one CWP for TRG position, two CWP for TWR position and one for ARO. Each CWP comprises of a Situation Data Display (SDD) and Flight Data Display (FDD) except TRG position which supports only SDD. The system also supports two Control and Monitoring Display (CMD) positions. Each CMD Display is supported by a SDD and FDD. The SDD at CMD positions cannot be used for assuming control of traffic.
19.1.3 The details of various operations of system are detailed in the operational manuals provided by INDRA.
19.1.4 The procedures and information provided in this SOP is intended to standardize and optimize the use of the system to provide maximum utility to controllers.
Note: Presently Radar inputs Guwahati, katihar, Radar are integrated to the Automation System. ADS-B Input for sensor located at Guwahati is also integrated to the AIRCON 2100 system.
19.2 The various Components, Location and their Functionalities
19.2.1 The Main components of the system are RDCUs, FDPs, SDPs, SNETs, SDDs, FDDs, CMDs, DRFs, CTSs and Voice Recorders.
19.2.2 The FDPs, SDPs, CTSs and Voice Recorders are located at the server room. One CMD for the Operational Supervisor is located with the WSO position in the Enroute Control Centre, whereas the other CMD is located in the Technical Supervisor Room with the Technical Supervisor. The DRF are located at the Technical Supervisor Room. Three CWPs are located at TWR; one each for TWR, SMC and ARO. Five CWPs are located in Enroute Control Centre for Enroute Control, Approach Control and Training.
19.2.3 Radar Communications Processor (RDCU): It processes surveillance data received in different format to integrate the same for feed to SDP.
19.2.4 Flight Data Processing (FDP): It manages the FPL and FPL data from external sources and that generated within the System including RPLs. It validates the flight data inputs, manages FPL life cycle, manages four dimensional trajectory calculations, manages FPL strips printing and keeps screen displays updated about the FPL and FPL related data. It manages alerts like Restricted Area Warning (RAW) and Frequency Alert (FQ). It feeds the processed FPL data to the SDP.
19.2.5 Surveillance Data Processor (SDP): It receives and processes surveillance data (primary, secondary, ADS and meteorological) coming from the radar and ADS sites. It receives processed FPL data from the FDP and facilitates functions like synthetic tracks generation, FPL track automatic correlation RAM, Heading Alert, Code Ambiguity and MTCD. It processes all the received information to create a coherent airspace picture for presentation at the SDDs. SNET process runs through the SDPs. SNET supports alert features like Area Proximity Warning (APW), Minimum Safe Altitude Warning (MSAW) and Short Term Conflict Alert (STC
