Full Smart Tower Automation
Air traffic service providers is possible to transmit clearance information to departing aircraft via datalink and Manage Flight Data Processing System, Rwy Lightning System/Stop Bar, accounting management, etc. with intelligent sysdatacom DCL-EFS system (Full Tower Automation).
■ Before leaving their parking stands at the start of a flight, pilots must request departure clearance – in the form of start-up and departure information. Typically, this will include operational data such as call sign, departure, and destination airport, runway to use, exit point, standard instrument departure, squawk code, departure time, ground ATC frequency and current atis identifier etc.
DCL-EFS system operate data immediately a significant change occurs as a result an automatic from Flight Data Processing/Radar, AFTN, d-atis, Accounting, RWY lighting and process the scenario related with airport operations automatically and operate this operational data to the Electronic Flight Strip (EFS). DCL system send this operational data to departing aircraft on fully automatic or semi-automatic mode. 
■ The DCL system can work in Fully Automatic, Semi-Automatic and Voice mode.
■ The System architecture will be open and modular both in software and hardware components. The system will be easily adapted and expanded to meet additional needs, such a new external interface, or implementation of extra services such as any combination of DCL-EFS services. Management Although it may vary according to local practice, the routine for delivery of DCL’s data link clearance is similar to VHF procedures:
■ In desired time before departure, the flight plan management system activates the flight.
■ Before departure, the pilot requests clearance via the data link terminal. The DCL request includes the same information elements as a voice DCL request.
■ The DCL-EFS Ground CWP checks each element of the received request and confirms that it corresponds to an existing flight plan. The Ground CWP will then send a positive or a negative request acknowledgment.
 
Logger
■ Records, all Flight Data Processing-Radar, d-atis, AFTN, Accounting, RWY lighting details and DCL Information on to the Database with Zulu time meaning History.
■ Logs all the alarms and status of the systems.
■ Any faults can be occurred on the system, will be recorded on to the  error database automatically.
■ Captured Controller Working Positions
 
Interconnecting
■ The DCL-EFS system is interfaced with the flight data processing system-Radar,  d-atis, AFTN, Accounting, RWY lighting, CPDLC or New External Interfaces which transmits information related to departing aircraft.
■ The system is also interfaced with Data Link Service Provider to provide communication with aircraft
 
Alarm and Error Management
■ Display Warning related with all the DCL – EFS data errors into the alarm window.
■ If the DCL information is not updated from FDP, EFS and DATIS data source appear warning into the alarm window for update delay.
■ In case of all alarm or error, a beep or speech sound is played from all terminals logged into the system and DCL system’s windows display an ERROR.
 
User HMI
■ Display and review activated, and processed flight plans on Electronic Flight Strip.
■ Display and review updated current d-atis information.
■ Display and review current runway status information.
■ Display and review or set the current scenario.
■ Display and check received DCL requests.
■ Display and review granted clearances.
■ Indicate readback/time out status.
■ Display the Electronic Flight Strip on the stand. 
■ Configure runway status automatically or manual.
■3, 4, 6 or more Controller Working Position (CWP) related with the size of airports. CWP can be devided or combined according to roles.
