45. Operation of air traffic control service
(1)An air traffic control unit, in order to provide air traffic control service shall—(a)be provided with information on the intended movement of each aircraft, or variations there from, and with current information on the actual progress of each aircraft;(b)determine from the information received, the relative positions of known aircraft to each other;(c)issue clearances and information for the purpose of preventing collision between aircraft under its control and of expediting and maintaining an orderly flow of traffic;(d)co-ordinate clearances as necessary with other units—(i)whenever an aircraft might otherwise conflict with traffic operated under the control of such other units;(ii)before transferring control of an aircraft to such other units.(2)Information on aircraft movements, together with a record of air traffic control clearances issued to such aircraft, shall be so displayed as to permit ready analysis in order to maintain an efficient flow of air traffic with adequate separation between aircraft.(3)Clearances issued by air traffic control units shall provide—(a)all flights in airspace Classes A and B;(b)IFR flights in airspace Classes C, D and E;(c)IFR flights and VFR flights in airspace Class C;(d)IFR flights and special VFR flights;(e)special VFR flights when so prescribed by the appropriate ATS authority.(4)A flight may be cleared without separation being provided in respect of a specific portion of the flight conducted in visual meteorological conditions when requested by an aircraft and if so prescribed by the appropriate ATS authority for the cases listed under subregulation (3)(b) in airspace Classes D and E.(5)Separation by an air traffic control unit shall be obtained by at least one of the following—(a)vertical separation, obtained by assigning different levels selected from—(i)the appropriate table of cruising levels described in the Civil Aviation (Rules of the air) Regulations, 2018; or(ii)a modified table of cruising levels, when so prescribed in accordance with the Civil Aviation (Rules of the air) Regulations, 2018 for flight above FL4I0, except that the correlation of levels to track as prescribed therein shall not apply whenever otherwise indicated in appropriate aeronautical information publications or air traffic control clearances;(b)horizontal separation, obtained by providing—(i)longitudinal separation, by maintaining an interval between aircraft operating along the same, converging or reciprocal tracks, expressed in time or distance; or(ii)lateral separation, by maintaining aircraft on different routes or in different geographical areas;(c)composite separation, consisting of a combination of vertical separation and one of the other forms of separation contained in subregulation (6)(b) using minima for each which may be lower than, but not less than half of, those used for each of the combined elements when applied individually.(6)Composite separation shall only be applied on the basis of regional air navigation agreements.(7)A programme shall be instituted, on a regional basis, for monitoring the height-keeping performance of aircraft operating at a reduced vertical separation minimum of 300 m (1 000 ft.) is applied between FL 290 and FL 410 inclusive, in order to ensure that the continued application of this vertical separation minimum meets the safety objectives.(8)The scope of regional monitoring programmes shall be adequate to conduct analyses of aircraft group performance and evaluate the stability of altimetry system error.(9)Where RCP/RSP specifications are applied, programmes shall be instituted for monitoring the performance of the infrastructure and the participating aircraft against the appropriate RCP and/or RSP specifications, to ensure that operations in the applicable airspace continue to meet safety objectives.(10)The scope of monitoring programmes shall be adequate to evaluate communication or surveillance performance, as applicable.(11)The scope of monitoring programmes shall be adequate to evaluate communication or surveillance performance, as applicable.
