4.2.5 With regard to the information provided by the transferring centre in accordance with 4.2.1 and 4.2.3, the accepting centre shall notify the transferring centre either that it is able to accept the aircraft concerned under the conditions specified or it shall specify to the transferring centre which changes to the flight plan are required so that the aircraft can be accepted; however, where special arrangements exist between the ATC units concerned, this notification shall only be required if the aircraft cannot be accepted as offered by the transferring centre.
4.2.6 The primary responsibility for the control of air traffic remains with the area control centre in whose control area the aircraft is operating until the time the aircraft is estimated to cross the boundary of that control area, even when control of one or more aircraft is exercised under delegation by other air traffic control units (see Annex 11, 3.5.2). It is emphasized that the accepting centre which is in communication with an aircraft not yet having reached the incoming transfer of control point shall not alter the clearance of such aircraft without the prior approval of the transferring centre.

Rules of the Air and Air Traffic Services (PANS-RAC)

Note.— When so agreed between the area control centres concerned, the transfer of control point may be a point other than the control area boundary.
4.2.7 In order to effect the transfer of control of an aircraft, the transferring centre shall, except as provided in 4.2.8, and in Part VI, 7.5.2, notify the accepting centre that the aircraft is in position to be handed over to it, and that the responsibility for control should be assumed by the accepting centre, either forthwith or, if a specified transfer of control point has been established, at the time when the aircraft passes that point. If the SSR Mode and Code currently radiated by the aircraft are known, and the accepting centre is able to make use of these data, they should be included in such notification. If transfer of radar control is to be effected, such notification shall also include information regarding the position (and track and speed, if required) of the radar position of the aircraft. Such notification shall also include significant changes in the data transmitted in accordance with 4.2.1 which have not been previously forwarded.
4.2.8 Where special arrangements exist between two area control centres which are not equipped with radar and which do not employ automatic data-processing equipment, the notification in 4.2.7 need only be made in circumstances where it is appropriate to forward a revision to previously transmitted current flight plan and control data at the time when the aircraft is in a position to be handed over to the accepting centre.
4.2.9 Where non-radar separation minima are being applied, the transfer of air-ground communications of an aircraft from the transferring to the accepting centre shall be made five minutes before the time at which the aircraft is estimated to reach the common control area boundary, unless otherwise agreed between the two area control centres concerned.
4.2.10 In circumstances where radar or ADS separation minima are being applied at the time of transfer of control, the transfer of air-ground voice and/or data communications of an aircraft from the transferring to the accepting centre shall be made immediately after the accepting centre has agreed to assume control unless the provisions of Part VI, 7.3.2 are applied.
4.2.11 A notification from the transferring centre that the aircraft will be cleared or has already been cleared to establish radio and/or data communications with the accepting centre is required in those cases where this has been agreed between the two area control centres concerned.
VIII. Co-ordination
4.2.12 The accepting centre shall notify the transferring centre that radio and/or data communication has been estab-lished with the aircraft being transferred and control of the aircraft has been assumed, unless otherwise specified by agreement between the area control centres concerned.
