13.5.1 Segregated parallel operations may be conducted on parallel runways provided:
* In preparation.
IV. Approach Control Service
a) the runway centre lines are spaced by the distance specified in Annex 14, Volume I; and
b) the nominal departure track diverges immediately after take-off by at least 30 degrees from the missed approach track of the adjacent approach (see Figure IV-5).
13.5.1.1 The minimum distance between parallel runway centre lines for segregated parallel operations may be decreased by 30 m for each 150 m that the arrival runway is staggered toward the arriving aircraft, to a minimum of 300 m (see Figure IV-6) and should be increased by 30 m for each 150 m that the arrival runway is staggered away from the arriving aircraft (see Figure IV-7).
13.5.2 The following types of approaches may be conducted in segregated parallel operations provided suitable surveillance radar and the appropriate ground facilities conform to the standard necessary for the specific type of approach:
a) ILS and/or MLS precision;
b) radar; and
c) visual.
Note.— Guidance material is contained in the Manual on Simultaneous Operations on Parallel or Near-Parallel Instrument Runways (Doc 9643).*
* In preparation.

14. Expected approach time
14.1 An expected approach time shall be determined for an arriving aircraft that will be subjected to a delay, and shall be transmitted to the aircraft as soon as practicable and preferably not later than at the commencement of its initial descent from cruising level. In the case of aircraft particularly sensitive to high fuel consumption at low levels, an expected approach time should, whenever possible, be transmitted to the aircraft early enough before its intended descent time to enable the pilot to choose the method of absorbing the delay and to request a change in the flight plan if the choice is to reduce speed en route. A revised expected approach time shall be transmitted to the aircraft without delay whenever it differs from that previously transmitted by 5 minutes or more, or such lesser period of time as has been established by the appropriate ATS authority or agreed between the ATS units concerned.
14.2 An expected approach time shall be transmitted to the aircraft by the most expeditious means whenever it is anticipated that the aircraft will be required to hold for thirty minutes or more.
14.3 The holding point to which an expected approach time relates shall be identified together with the expected approach time whenever circumstances are such that this would not otherwise be evident to the pilot.
15. Information for arriving aircraft
Note.— See Part IX, 4.3 regarding flight information messages.
6/11/97
No. 1
15.1 As early as practicable after an aircraft has established communication with the unit providing approach control service, the following elements of information, in the order listed, shall be transmitted to the aircraft, with the exception of such elements which it is known the aircraft has already received:
a) runway-in-use;
b) meteorological information, as follows:
1) surface wind direction and speed, including significant variations;
2) visibility and, when applicable, runway visual range (RVR);
3) present weather;
