The Civil Aviation Authority of Italy (ENAC) is the national regulator in the technical, economical and operational aviation field and certifies airlines, airports, air navigation service providers (ANSP), manufacturers, maintenance, repair and overhaul (MRO) organisations, ground handlers, etc. ENAC is engaged in dealing with the diverse regulatory aspects of air transport system and performs monitoring functions related to the enforcement of the adopted rules regulating administrative and economical issues. Its core business is doubtless represented by safety control, in its double meaning of safety and security, according to internationally agreed terms of reference. Safety is understood as the safe planning, construction, maintenance and exploitation of aircraft, as well as the skill assessment of air carriers and inflight personnel. Security is meant as the land-side safeguard of passengers, on board aircraft, inside and outside the airports, aimed at the prevention of illicit acts. ENAC represents Italy in the major international civil aviation organisations such as ICAO , ECAC, EASA and the European Organisation for the Safety of Air Navigation (Eurocontrol) with which ENAC undertakes a continuous dialogue and co-operation. The specific tasks in NCPS in the event of an emergency include the supply of information regarding the operability and capacity of airports, air routes and heliports in the areas affected by the emergency as well as adoption of necessary regulations, in order to facilitate rescue operations, limiting ordinary and commercial flight activities in the airports concerned by the event and identifying alternative intermediate stops and rerouting air traffic.
