Note.— Approach control service may be provided by a unit collocated with an ACC, or by a control sector within an ACC. 4.1.3 Aerodrome control service Aerodrome control service shall be provided by an aerodrome control tower. 4.2 RESPONSIBILITY FOR THE PROVISION OF FLIGHT INFORMATION SERVICE AND ALERTING SERVICE Flight information service and alerting service shall be provided as follows: a) within a flight information region (FIR): by a flight information centre, unless the responsibility for providing such services is assigned to an air traffic control unit having adequate facilities for the exercise of such responsibilities; b) within controlled airspace and at controlled aerodromes: by the relevant air traffic control units.

Where there is more than one ATC working position within a unit or sector, the duties and responsibilities of the individual working positions shall be defined. 4.3.2 Between a unit providing aerodrome control service and a unit providing approach control service 4.3.2.1 Except for flights which are provided aerodrome control service only, the control of arriving and departing controlled flights shall be divided between units providing aerodrome control service and units providing approach control service as follows: 4.3.2.1.1 Arriving aircraft. Control of an arriving aircraft shall be transferred from the unit providing approach control service to the unit providing aerodrome control service when the aircraft: a) is in the vicinity of the aerodrome, and 1) it is considered that approach and landing will be completed in visual reference to the ground, or 2) has reached uninterrupted visual meteorological conditions, or b) is at a prescribed point or level, or c) has landed, --```,,``````,,`,``,```,,`,`,,,-`-`,,`,,`,`,,`--- as specified in letters of agreement or ATS unit instructions. 4.3.2.1.2 Transfer of communications to the aerodrome controller should be effected at such a point, level or time that clearance to land or alternative instructions, as well as information on essential local traffic, can be issued in a timely manner. Note.— Even though there is an approach control unit, control of certain flights may be transferred directly from an ACC to an aerodrome control tower and vice versa, by prior arrangement between the units concerned for the relevant part of approach control service to be provided by the ACC or the aerodrome control tower, as applicable. 4.3.2.1.3 Departing aircraft. Control of a departing aircraft shall be transferred from the unit providing aerodrome control service to the unit providing approach control service: a) when visual meteorological conditions prevail in the vicinity of the aerodrome: 1) prior to the time the aircraft leaves the vicinity of the aerodrome, 2) prior to the aircraft entering instrument meteorological conditions, or 3) when the aircraft is at a prescribed point or level, as specified in letters of agreement or ATS unit instructions; 10/11/16 Copyright International Civil Aviation Organization Provided by IHS Markit under license with ICAO Licensee=Abu Dhabi Airport Company/5964583001, User=AlYammahi, ahmed No reproduction or networking permitted without license from IHS Not for Resale, 03/21/2021 04:52:06 MDT  Chapter 4. General Provisions for Air Traffic Services 4-3 b) when instrument meteorological conditions prevail at the aerodrome: 1) immediately after the aircraft is airborne, or 2) when the aircraft is at a prescribed point or level, as specified in letters of agreement or local instructions. Note.— See Note following 4.3.2.1.2. 4.3.3 Between a unit providing approach control service and a unit providing area control service 4.3.3.1 When area control service and approach control service are not provided by the same air traffic control unit, responsibility for controlled flights shall rest with the unit providing area control service except that a unit providing approach control service shall be responsible for the control of: a) arriving aircraft that have been released to it by the ACC; b) departing aircraft until such aircraft are released to the ACC. 4.3.3.2 A unit providing approach control service shall assume control of arriving aircraft, provided such aircraft have been released to it, upon arrival of the aircraft at the point, level or time agreed for transfer of control, and shall maintain control during approach to the aerodrome. 4.3.4 Between two units providing area control service The responsibility for the control of an aircraft shall be transferred from a unit providing area control service in a control area to the unit providing area control service in an adjacent control area at the time of crossing the common control area boundary as estimated by the ACC having control of the aircraft or at such other point, level or time as has been agreed between the two units. 4.3.5 Between control sectors/positions within the same air traffic control unit The responsibility for the control of an aircraft shall be transferred from one control sector/position to another control sector/position within the same ATC unit at a point, level or time, as specified in local instructions. 4.4 FLIGHT PLAN 4.4.1 Flight plan form Note.— Procedures for the use of repetitive flight plans are contained in Chapter 16, Section 16.4. 4.4.1.1 A flight plan form based on the model in Appendix 2 should be provided and should be used by operators and air traffic services units for the purpose of completing flight plans.
