   THE EUROPEAN COMMISSION,
   Having regard to the Treaty on the Functioning of the European Union,
   Having regard to Regulation (EC) No 551/2004 of the European Parliament and of the Council of 10 March 2004 on the organisation and use of the airspace in the single European sky (1) (the airspace Regulation), and in particular Article 4(a) and (b) thereof,
   Having regard to Regulation (EC) No 216/2008 of the European Parliament and of the Council of 20 February 2008 on common rules in the field of civil aviation and establishing a European Aviation Safety Agency (2) (the EASA Basic Regulation), and in particular Articles 8 and 8b and Annex Vb thereto,
   Whereas:
   
               (1)
            
            
               Pursuant to Regulation (EC) No 551/2004 and Regulation (EC) No 216/2008, the Commission is required to adopt implementing rules in order to adopt appropriate provisions on rules of the air based upon Standards and recommended practices of the International Civil Aviation Organisation (ICAO), and to harmonise the application of the ICAO airspace classification, with the aim to ensure the seamless provision of safe and efficient air traffic services within the single European sky.
            
         
               (2)
            
            
               Eurocontrol has been mandated in accordance with Article 8(1) of Regulation (EC) No 549/2004 of the European Parliament and the Council of 10 March 2004 laying down the framework for the creation of the single European sky (3) to assist the Commission in the development of implementing rules which lay down appropriate provisions on rules of the air based upon ICAO Standards and recommended practices, and harmonise the application of the ICAO airspace classification.
            
         
               (3)
            
            
               In accordance with Articles 1(3) and 13 of Regulation (EC) No 549/2004 and Article 2 of Regulation (EC) No 216/2008, the single European sky initiative should assist the Member States in fulfilling their obligations under the 1944 Chicago Convention on International Civil Aviation (hereafter the Chicago Convention) by providing for common interpretation and implementation.
            
         
               (4)
            
            
               The objective of Regulation (EC) No 551/2004 is to support the concept of a more integrated operating airspace within the context of the common transport policy, and to establish common procedures for design, planning and management while ensuring the efficient and safe performance of air traffic management. This objective is particularly relevant for the rapid implementation of functional airspace blocks in the single European sky.
            
         
               (5)
            
            
               The outcome of the work undertaken by the joint group created by the Commission, Eurocontrol and ICAO, which charted the national differences filed by Member States relating to ICAO Standards dealing with rules of the air and related provisions for air navigation services, supports the need for standardisation of common rules and differences with respect to the single European sky.
            
         
               (6)
            
            
               In order to ensure safe, efficient and expeditious international air traffic and to support the establishment of functional airspace blocks, all participants in the single European sky should adhere to a common set of rules. Furthermore, a key enabler of safe cross-border operations is the creation of a transparent regulatory system, where the actors can be provided a legal certainty and predictability. To this end, standardised rules of the air and related operational provisions regarding services and procedures in air navigation should be established, and be supplemented, where appropriate, with guidance material and/or acceptable means of compliance.
            
         
               (7)
            
            
               To achieve those objectives, only commonly agreed European differences should be notified to ICAO by the Member States on areas which are covered by Union law. Those differences should be established and monitored through a permanent process.
            
         
               (8)
            
            
               Member States that have adopted additional provisions complementing an ICAO standard, should, if they are still considered necessary and provided such additional provisions do not constitute a difference under the Chicago Convention or against existing Union law, continue to apply such provisions until they are addressed by appropriate Union provisions.
            
         
               (9)
            
            
               The application of this Regulation should be without prejudice to the Member States’ obligations and rights over the high seas, in accordance with Article 12 of the Chicago Convention, and in particular with Annex 2 to the Chicago Convention, as well as the obligations of Member States and the Union under the United Nations Convention on the Law of the Sea and the obligations of Member States under the Convention on the International Regulations for Preventing Collisions at Sea, 1972.
            
         
               (10)
            
            
               In accordance with Article 1(2) of the framework Regulation (EC) No 549/2004, the regulatory framework for the creation of the single European sky does not cover military operations and training.
            
         
               (11)
            
            
               The existing process for amending ICAO Standards and recommended practices within the framework of the Chicago Convention is not addressed by this Regulation.
            
         
               (12)
            
            
               The extension of the competence of EASA to include air traffic management safety requires consistency between the development of implementing rules under Regulations (EC) No 551/2004 and (EC) No 216/2008.
            
         
               (13)
            
            
               In order to ensure consistency between the transposition of provisions of Annex 2 to the Chicago Convention set out in this Regulation and the future provisions stemming from other annexes to the Chicago Convention, which will be included in the next stages of work as well as the implementation of future Union rules, the initial provisions should be revisited where necessary.
            
         
               (14)
            
            
               Where necessary, other Union legislation should be updated to refer to this Regulation,

      CHAPTER 2
      
         Avoidance of collisions
      
      
         SERA.3201   General
      
      Nothing in this Regulation shall relieve the pilot-in-command of an aircraft from the responsibility of taking such action, including collision avoidance manoeuvres based on resolution advisories provided by ACAS equipment, as will best avert collision.
      
         SERA.3205   Proximity
      
      An aircraft shall not be operated in such proximity to other aircraft as to create a collision hazard.
      
         SERA.3210   Right-of-way
      
      
                  (a)
               
               
                  The aircraft that has the right-of-way shall maintain its heading and speed.
               
            
                  (b)
               
               
                  An aircraft that is aware that the manoeuvrability of another aircraft is impaired shall give way to that aircraft.
               
            
                  (c)
               
               
                  An aircraft that is obliged by the following rules to keep out of the way of another shall avoid passing over, under or in front of the other, unless it passes well clear and takes into account the effect of aircraft wake turbulence.
                  
                              (1)
                           
                           
                              
                                 Approaching head-on. When two aircraft are approaching head-on or approximately so and there is danger of collision, each shall alter its heading to the right.
                           
                        
                              (2)
                           
                           
                              
                                 Converging. When two aircraft are converging at approximately the same level, the aircraft that has the other on its right shall give way, except as follows:
                              
                                          (i)
                                       
                                       
                                          power-driven heavier-than-air aircraft shall give way to airships, sailplanes and balloons;
                                       
                                    
                                          (ii)
                                       
                                       
                                          airships shall give way to sailplanes and balloons;
                                       
                                    
                                          (iii)
                                       
                                       
                                          sailplanes shall give way to balloons;
                                       
                                    
                                          (iv)
                                       
                                       
                                          power-driven aircraft shall give way to aircraft which are seen to be towing other aircraft or objects.
                                       
                                    
                        
                              (3)
                           
                           
                              
                                 Overtaking. An overtaking aircraft is an aircraft that approaches another from the rear on a line forming an angle of less than 70 degrees with the plane of symmetry of the latter, i.e. is in such a position with reference to the other aircraft that at night it should be unable to see either of the aircraft’s left (port) or right (starboard) navigation lights. An aircraft that is being overtaken has the right-of-way and the overtaking aircraft, whether climbing, descending or in horizontal flight, shall keep out of the way of the other aircraft by altering its heading to the right, and no subsequent change in the relative positions of the two aircraft shall absolve the overtaking aircraft from this obligation until it is entirely past and clear.
                              
                                          (i)
                                       
                                       
                                          
                                             Sailplanes overtaking. A sailplane overtaking another sailplane may alter its course to the right or to the left.
                                       
                                    
                        
                              (4)
                           
                           
                              
                                 Landing. An aircraft in flight, or operating on the ground or water, shall give way to aircraft landing or in the final stages of an approach to land.
                              
                                          (i)
                                       
                                       
                                          When two or more heavier-than-air aircraft are approaching an aerodrome or an operating site for the purpose of landing, aircraft at the higher level shall give way to aircraft at the lower level, but the latter shall not take advantage of this rule to cut in front of another which is in the final stages of an approach to land, or to overtake that aircraft. Nevertheless, power-driven heavier-than-air aircraft shall give way to sailplanes.
                                       
                                    
                                          (ii)
                                       
                                       
                                          
                                             Emergency landing. An aircraft that is aware that another is compelled to land shall give way to that aircraft.
                                       
                                    
                        
                              (5)
                           
                           
                              
                                 Taking off. An aircraft taxiing on the manoeuvring area of an aerodrome shall give way to aircraft taking off or about to take off.

                  Surface movement of aircraft, persons and vehicles.
                  
                              (1)
                           
                           
                              In case of danger of collision between two aircraft taxiing on the movement area of an aerodrome or equivalent part of an operating site, the following shall apply:
                              
                                          (i)
                                       
                                       
                                          when two aircraft are approaching head on, or approximately so, each shall stop or where practicable alter its course to the right so as to keep well clear;
                                       
                                    
                                          (ii)
                                       
                                       
                                          when two aircraft are on a converging course, the one which has the other on its right shall give way;
                                       
                                    
                                          (iii)
                                       
                                       
                                          an aircraft which is being overtaken by another aircraft shall have the right-of-way and the overtaking aircraft shall keep well clear of the other aircraft.
                                       
                                    
                        
                              (2)
                           
                           
                              At a controlled aerodrome an aircraft taxiing on the manoeuvring area shall stop and hold at all runway-holding positions unless an explicit clearance to enter or cross the runway has been issued by the aerodrome control tower.

                  (a)
               
               
                  Subject to the provisions of SERA.8020 (b) all changes to a flight plan submitted for an IFR flight, or a VFR flight operated as a controlled flight, shall be reported as soon as practicable to the appropriate air traffic services unit. For other VFR flights, significant changes to a flight plan shall be reported as soon as practicable to the appropriate air traffic services unit.
               
            
                  (b)
               
               
                  Information submitted prior to departure regarding fuel endurance or total number of persons carried on board, if incorrect at time of departure, constitutes a significant change to the flight plan and as such shall be reported.
               
            
         SERA.4020   Closing a flight plan
      
      
                  (a)
               
               
                  An arrival report shall be made in person, by radiotelephony, via data link or by other means as prescribed by the competent authority at the earliest possible moment after landing, to the appropriate air traffic services unit at the arrival aerodrome, by any flight for which a flight plan has been submitted covering the entire flight or the remaining portion of a flight to the destination aerodrome.
                  
                              (1)
                           
                           
                              Submission of an arrival report is not required after landing on an aerodrome where air traffic services are provided on condition that radio communication or visual signals indicate that the landing has been observed.
                           
                        
            
                  (b)
               
               
                  When a flight plan has been submitted only in respect of a portion of a flight, other than the remaining portion of a flight to destination, it shall, when required, be closed by an appropriate report to the relevant air traffic services unit.
               
            
                  (c)
               
               
                  When no air traffic services unit exists at the arrival aerodrome or operating site, the arrival report, when required, shall be made as soon as practicable after landing and by the quickest means available to the nearest air traffic services unit.
               
            
                  (d)
               
               
                  When communication facilities at the arrival aerodrome or operating site are known to be inadequate and alternate arrangements for the handling of arrival reports on the ground are not available, the following action shall be taken. Immediately prior to landing the aircraft shall, if practicable, transmit to the appropriate air traffic services unit, a message comparable to an arrival report, where such a report is required. Normally, this transmission shall be made to the aeronautical station serving the air traffic services unit in charge of the flight information region in which the aircraft is operated.

                              transition levels, whether issued by the controller or contained in ATIS broadcasts.
                           
                        
            
                  (2)
               
               
                  Other clearances or instructions, including conditional clearances and taxi instructions, shall be read back or acknowledged in a manner to clearly indicate that they have been understood and will be complied with.
               
            
                  (3)
               
               
                  The controller shall listen to the read-back to ascertain that the clearance or instruction has been correctly acknowledged by the flight crew and shall take immediate action to correct any discrepancies revealed by the read-back.
               
            
                  (4)
               
               
                  Voice read-back of CPDLC messages shall not be required, unless otherwise specified by the ANSP.
               
            (f)   Coordination of clearances
      
                  (1)
               
               
                  An air traffic control clearance shall be coordinated between air traffic control units to cover the entire route of an aircraft or a specified portion thereof as described in provisions (2) to (6).
               
            
                  (2)
               
               
                  An aircraft shall be cleared for the entire route to the aerodrome of first intended landing:
                  
                              (i)
                           
                           
                              when it has been possible, prior to departure, to coordinate the clearance between all the units under whose control the aircraft will come; or
                           
                        
                              (ii)
                           
                           
                              when there is reasonable assurance that prior coordination will be effected between those units under whose control the aircraft will subsequently come.
                           
                        
            
                  (3)
               
               
                  When coordination as in (2) has not been achieved or is not anticipated, the aircraft shall be cleared only to that point where coordination is reasonably assured; prior to reaching such point, or at such point, the aircraft shall receive further clearance, holding instructions being issued as appropriate.
               
            
                  (4)
               
               
                  When prescribed by the ATS unit, aircraft shall contact a downstream air traffic control unit, for the purpose of receiving a downstream clearance prior to the transfer of control point.
                  
                              (i)
                           
                           
                              Aircraft shall maintain the necessary two-way communication with the current air traffic control unit whilst obtaining a downstream clearance.
                           
                        
                              (ii)
                           
                           
                              A clearance issued as a downstream clearance shall be clearly identifiable as such to the pilot.
                           
                        
                              (iii)
                           
                           
                              Unless coordinated, downstream clearances shall not affect the aircraft’s original flight profile in any airspace, other than that of the air traffic control unit responsible for the delivery of the downstream clearance.
                           
                        
            
                  (5)
               
               
                  When an aircraft intends to depart from an aerodrome within a control area to enter another control area within a period of thirty minutes, or such other specific period of time as has been agreed between the area control centres concerned, coordination with the subsequent area control centre shall be effected prior to issuance of the departure clearance.
               
            
                  (6)
               
               
                  When an aircraft intends to leave a control area for flight outside controlled airspace, and will subsequently re-enter the same or another control area, a clearance from the point of departure to the aerodrome of first intended landing may be issued. Such clearance or revisions thereto shall apply only to those portions of the flight conducted within controlled airspace.
               
            
         SERA.8020   Adherence to flight plan
      
      
                  (a)
               
               
                  Except as provided for in (b) and (d) an aircraft shall adhere to the current flight plan or the applicable portion of a current flight plan submitted for a controlled flight unless a request for a change has been made and clearance obtained from the appropriate air traffic control unit, or unless an emergency situation arises which necessitates immediate action by the aircraft, in which event as soon as circumstances permit, after such emergency authority is exercised, the appropriate air traffic services unit shall be notified of the action taken and that this action has been taken under emergency authority.
                  
                              (1)
                           
                           
                              Unless otherwise authorised by the competent authority, or directed by the appropriate air traffic control unit, controlled flights shall, in so far as practicable:
                              
                                          (i)
                                       
                                       
                                          when on an established ATS route, operate along the defined centre line of that route; or
                                       
                                    
                                          (ii)
                                       
                                       
                                          when on any other route, operate directly between the navigation facilities and/or points defining that route.
                                       
                                    
                        
                              (2)
                           
                           
                              Unless otherwise authorised by the competent authority, or directed by the appropriate air traffic control unit, an aircraft operating along an ATS route segment defined by reference to very high frequency omnidirectional radio ranges shall change over for its primary navigation guidance from the facility behind the aircraft to that ahead of it at, or as close as operationally feasible to, the changeover point, where established.
                           
                        
                              (3)
                           
                           
                              Deviation from the requirements in (2) shall be notified to the appropriate air traffic services unit.

                     Inadvertent changes. In the event that a controlled flight inadvertently deviates from its current flight plan, the following action shall be taken:
                  
                              (1)
                           
                           
                              Deviation from track: if the aircraft is off track, action shall be taken forthwith to adjust the heading of the aircraft to regain track as soon as practicable.
                           
                        
                              (2)
                           
                           
                              Variation in true airspeed: if the average true airspeed at cruising level between reporting points varies or is expected to vary by plus or minus 5 per cent of the true airspeed, from that given in the flight plan, the appropriate air traffic services unit shall be so informed.
                           
                        
                              (3)
                           
                           
                              Change in time estimate: if the time estimate for the next applicable reporting point, flight information region boundary or destination aerodrome, whichever comes first, is found to be in error in excess of 3 minutes from that notified to air traffic services, or such other period of time as is prescribed by the competent authority or on the basis of ICAO regional air navigation agreements, a revised estimated time shall be notified as soon as possible to the appropriate air traffic services unit.
                           
                        
                              (4)
                           
                           
                              Additionally, when an ADS-C agreement is in place, the air traffic services unit shall be informed automatically via data link whenever changes occur beyond the threshold values stipulated by the ADS-C event contract.

                              request an amended clearance enabling the aircraft to continue in VMC to destination or to an alternative aerodrome, or to leave the airspace within which an ATC clearance is required; or
                           
                        
                              (2)
                           
                           
                              if no clearance in accordance with a) can be obtained, continue to operate in VMC and notify the appropriate ATC unit of the action being taken either to leave the airspace concerned or to land at the nearest suitable aerodrome; or

                              DAY or NIGHT — Raising landing gear (if fitted) and flashing landing lights while passing over runway in use or helicopter landing area at a height exceeding 300 m (1 000 ft) but not exceeding 600 m (2 000 ft) (in the case of a helicopter, at a height exceeding 50 m (170 ft) but not exceeding 100 m (330 ft)) above the aerodrome level, and continuing to circle runway in use or helicopter landing area. If unable to flash landing lights, flash any other lights available.
                           
                           
                              Aerodrome you have designated is inadequate.
                           
                           
                              DAY or NIGHT — If it is desired that the intercepted aircraft follow the intercepting aircraft to an alternate aerodrome, the intercepting aircraft raises its landing gear (if fitted) and uses the Series 1 signals prescribed for intercepting aircraft.
                              If it is decided to release the intercepted aircraft, the intercepting aircraft uses the Series 2 signals prescribed for intercepting aircraft.

                  Helicopters may be permitted to operate in less than 1 500 m but not less than 800 m flight visibility, if manoeuvred at a speed that will give adequate opportunity to observe other traffic or any obstacles in time to avoid collision. Flight visibilities lower than 800 m may be permitted for special cases, such as medical flights, search and rescue operations and fire-fighting.
               
            
         (4)  These elements are replaced by the term ‘CAVOK’ when the following conditions occur simultaneously at the time of observation: (a) visibility, 10 km or more, and the lowest visibility not reported; (b) no cloud of operational significance; and (c) no weather of significance to aviation.
      
         (5)  These elements are replaced by the term ‘CAVOK’ when the following conditions occur simultaneously at the time of observation: (a) visibility, 10 km or more, and the lowest visibility not reported; (b) no cloud of operational significance; and (c) no weather of significance to aviation.
