2. SERVICES
2.1.1. The data used as a source for aeronautical information shall be of sufficient quality, complete, current and provided in a timely manner. 2.1.2. Aeronautical information shall be accurate, complete, current, unambiguous, from a legitimate source, and of adequate integrity, as well as in a format suitable for users. 2.1.3. The dissemination of such aeronautical information to airspace users shall be timely and use sufficiently reliable and expeditious means of communication protected from intentional and unintentional interference and corruption. 2.2.1. The data used as a source for aeronautical meteorological information shall be of sufficient quality, complete and current. 2.2.2. To the extent possible, aeronautical meteorological information shall be precise, complete, current, of adequate integrity and unambiguous in order to meet the needs of airspace users. Aeronautical meteorological information shall be from a legitimate source. 2.2.3. The dissemination of such aeronautical meteorological information to airspace users shall be timely and use sufficiently reliable and expeditious means of communication protected from interference and corruption. 2.3.1. The data used as a source for the provision of air traffic services shall be correct, complete and current. 2.3.2. The provision of air traffic services shall be sufficiently precise, complete, current, and unambiguous to meet the safety needs of users. 2.3.3. Automated tools providing information or advice to users shall be properly designed, produced and maintained to ensure that they are fit for their intended purpose. 2.3.4. Air traffic control services and related processes shall provide for adequate separation between aircraft and, on the aerodrome manoeuvring area, prevent collisions between aircraft and obstructions and, where appropriate, assist in protection from other airborne hazards and shall ensure prompt and timely coordination with all relevant users and adjacent volumes of airspace. 2.3.5. Communication between air traffic services and aircraft and between relevant air traffic services units shall be timely, clear, correct and unambiguous, protected from interference and commonly understood and, if applicable, acknowledged by all actors involved. 2.3.6. Means shall be in place to detect possible emergencies and, when appropriate, to initiate effective search and rescue action. Such means shall, as a minimum, comprise appropriate alerting mechanisms, coordination measures and procedures, means and personnel to cover the area of responsibility efficiently. Communication services shall achieve and maintain sufficient performance with regard to their availability, integrity, continuity and timeliness. They shall be expeditious and protected from corruption and interference. Navigation services shall achieve and maintain a sufficient level of performance with regard to guidance, positioning and, when provided, timing information. The performance criteria include accuracy, integrity, legitimacy of the source, availability, and continuity of the service. Surveillance services shall determine the respective position of aircraft in the air and of other aircraft and ground vehicles on the aerodrome surface, with sufficient performance with regard to their accuracy, integrity, legitimacy of the source, continuity and probability of detection. The tactical management of air traffic flows at Union level shall use and provide sufficiently precise and current information of the volume and nature of the planned air traffic affecting service provision and shall coordinate and negotiate re-routing or delaying traffic flows in order to reduce the risk of overloading situations occurring in the air or at the aerodromes. Flow management shall be performed with a view to optimising available capacity in the use of airspace and enhancing air traffic flow management processes. It shall be based on safety, transparency and efficiency, ensuring that capacity is provided in a flexible and timely manner, consistent with the European Air Navigation Plan. The measures referred to in Article 43, concerning flow management shall support operational decisions by air navigation service providers, aerodrome operators and airspace users and shall cover the following areas: flight planning; use of available airspace capacity during all phases of flight, including en-route slot assignment; use of routings by general air traffic, including: the creation of a single publication for route and traffic orientation, options for diversion of general air traffic from congested areas, and priority rules regarding access to airspace for general air traffic, particularly during periods of congestion and crisis; and the consistency between flight plans and airport slots and the necessary coordination with adjacent regions, as appropriate. The designation of specific volumes of airspace for a certain use shall be monitored, coordinated and promulgated in a timely manner in order to reduce the risk of loss of separation between aircraft in all circumstances. Taking into account the organisation of military activities and related aspects under the responsibility of the Member States, airspace management shall also support the uniform application of the concept of the flexible use of airspace as described by the ICAO and as implemented under Regulation (EC) No 551/2004, in order to facilitate airspace management and air traffic management in the context of the common transport policy. Flight procedures shall be properly designed, surveyed and validated before they can be deployed and used by aircraft.
