or SUPER aircraft has:

(a)         used the same runway in the same or reciprocal direction; and

(b)         taken-off or made a low or missed approach.

10.12.3.5     ATC must issue a wake turbulence caution to the pilot of an aircraft if:

(a)         less than the applicable wake turbulence separation minima may exist; or

(b)         the applied wake turbulence separation minima may be infringed; or

(c)          the pilot has waived the relevant departure wake turbulence separation requirement; or

(d)         wake turbulence separation is not provided because of paragraph 10.12.3.3 (d) or (e), and wake turbulence may have an adverse effect on the aircraft.

10.12.3.6     In applying wake turbulence separation minima, air traffic controllers must:
(a)         when using a time minimum between aircraft taking-off, ensure that a following aircraft does not become airborne until the specified time interval has elapsed since the leading aircraft became airborne;
(b)         when using a time minimum between an aircraft executing a missed approach and the following aircraft taking-off, not issue the take-off clearance until the specified time interval has elapsed since the preceding aircraft crossed the threshold or initiated the missed approach (whichever occurs later);
(c)          when using an ATS surveillance system minimum between aircraft taking off, ensure that the appropriate separation minimum exists between the aircraft at or before the time the following aircraft becomes airborne;
(d)         when aircraft are using the same runway, ensure that the landing minimum will exist at the time the leading aircraft is over the landing threshold;
(e)         when crossing runways are in use, apply the full length minima and ensure that the required separation exists at the intersection.

10.12.3.7     If the required wake turbulence separation can be determined by distance using an aircraft report or ATS surveillance system, ATC is not required to apply the relevant time minimum:
(a)         between arriving aircraft; or
(b)         unless the aircraft following will commence take-off from an intermediate point — between departing aircraft.
Note Intermediate point is explained in subsection 10.12.1.

10.12.3.8     Due to the wake turbulence characteristics of the B757 and H47, for the purpose of wake turbulence separation, these aircraft must be classified as a HEAVY aircraft if leading and as a MEDIUM aircraft if following.

Section 10.13:   Separation Standards—Aerodrome

10.13.1         Taxiing and Runway Standards

10.13.1.1     The separation of aircraft taxiing on the manoeuvring area is a joint pilot and controller responsibility.

10.13.1.2     When providing runway separation, the wake turbulence standards must be applied in conjunction with the runway standards.

10.13.1.3     Runway separation standards apply equally to runway operations or to a strip having a single landing and take-off path.

10.13.1.4     When take-off or landing separation is based on the position of a preceding landing or taxiing aircraft and visual determination is
