Mission:
The ENAV Automatic Terminal Information Service (e-ATIS) developed by Techno Sky allows automatic transmission of meteorological and aeronautical information to aircrafts by means of continuous radio broadcast or datalink, in order to reduce both ATC and aircraft crews workload. 

Operational Scenario:
The e-ATIS system can be combined with Techno Sky’s e-AWOS system, AMHS/AFTN systems or third party AWOS class systems, allowing aircrafts crew, preparing for landing and takeoff operations, to retrieve up to date critical information without contacting ATC personnel. Nowadays the e-ATIS system is operating at over 20 airports.

Key Benefits:
• Improvement of automated operational processes, allowing ATC operators to achieve efficient and safe operations
• Minimization of ATC operators workload and human intervention, reducing the air/ground communications between TWR/APP and pilots
• Easy integration with existing third party systems
• Easy HMI customization according to users requirements
• Reliable and flexible solution, suitable to be upgraded according to the ICAO amendments or local operational needs

Main technical features and overview:
• Data acquisition, validation, elaboration and quality check, in accordance with all relevant international standards
• Automated building of text messages according to configurable and appropriate syntax and semantic
• Continuous update of aeronautical and meteorological information
• Conversion to a high-quality audio stream based on a speech synthesis technology
• Offline configuration to manage a single message for both landing and taking-off aircrafts or distinct messages for arrival and departure traffic
• Facilities to insert additional aeronautical information or explicit emergency messages
• Manual data insertion in case of unavailability of upstream systems or meteorological sensors
• Analog broadcast over a VHF/VOR transmitter to aircrafts
• Digital broadcast over ARINC/SITA networks to aircrafts by means of an external Datalink system
• Local data storage and archive consultation of received meteorological data and created messages
• Provision of ATIS messages to external users by means of a phone analog line and a voicemail system
• Management of aeronautical dictionary and predefined messages
