to be flown at the clearance limit is not required when:

(a)         the holding point is published in aeronautical documents;

(b)         a clearance limit has been imposed temporarily and it is expected that the requirement to hold will have elapsed before the aircraft arrives at the designated holding point.

12.1.6              Clearance Readbacks

12.1.6.1         ATS personnel must ensure that those elements identified in AIP are to be read back correctly by the pilot.

12.1.7              Transfer of identification

12.1.7.1         Transfer of identification may be carried out by 1 of the following methods:

(a)         designation of the position indication by automated means, if only 1 position indication is indicated and there is no possible doubt of correct identification;

(b)         notification of the aircraft's discrete SSR code or aircraft address;

(c)          notification that the aircraft is SSR Mode S-equipped with an aircraft identification feature when SSR Mode S coverage is available;

(d)         notification that the aircraft is ADS-B equipped with an aircraft identification feature when compatible ADS-B coverage is available;

(e)         direct designation (pointing with the finger) of the position indication, if the 2 situation displays are adjacent, or if a common conference type of situation display is used;
Note: Attention must be given to any errors which might occur due to parallax effects.

(f)            designation of the position indication by reference to, or in terms of, bearing and distance from a geographical position or navigational facility accurately indicated on both situation displays, together with the track of the observed position indication if the route of the aircraft is not known to both controllers;
Note: Caution must be exercised before transferring identification using this method, particularly if other position indications are observed on similar headings and in close proximity to the aircraft under control. Inherent radar deficiencies, such as inaccuracies in bearing and distance of the radar position indications displayed on individual situation displays and parallax errors, may cause the indicated position of an aircraft in relation to the known point to differ between the 2 situation displays.

(g)         the transferring controller instructing the aircraft to change SSR code, and the accepting controller observing the change;

(h)         the transferring controller instructing the aircraft to squawk/transmit IDENT, and the accepting controller observing this response.
Note: Use of procedures (g) and (h) requires prior coordination between the controllers, since the indications to be observed by the accepting controller are of short duration.

12.1.8              Clearance by Establishment of 2-way Communications

12.1.8.1         For this subsection, 2-way communication is established if ATC responds to a pilot's radio call with the aircraft's radio identification.

12.1.8.2         In addition to issuing a pilot with a specific clearance or instruction, ATC may authorise an aircraft to enter Class D airspace by establishing 2-way
