both aircraft are using the same runway for take-off or for landing; or

(b)         an aircraft taking-off behind a landing heavier wake turbulence category aircraft is expected to become airborne before the touchdown point of the landing aircraft; or

(c)          an aircraft is taking-off and a preceding departing aircraft on a crossing runway has rotated at or before the runway intersection; or

(d)         an aircraft is landing and could still be airborne at the intersection of a crossing runway and a preceding departing aircraft on that crossing runway has rotated at or before the intersection; or

(e)         a LIGHT aircraft during its landing run will cross the intersection of a crossing runway behind a departing HEAVY aircraft on that crossing runway which has rotated at or before the intersection; or

(f)            using parallel runways for approach and departures when the runways are separated by less than 760 m; or

(g)         an aircraft is using the opposite direction runway for take-off or landing to a heavier category aircraft that has taken off or executed a missed approach.

10.12.3.3     ATC is not required to apply wake turbulence separation in the following situations:

(a)         when a MEDIUM fixed-wing aircraft of less than 25 000 kg MTOW precedes a LIGHT aircraft;

(b)         when an aircraft is landing behind another aircraft that is taking-off on the same runway;

(c)          subject to 10.12.3.4, if a pilot has initiated a waiver of the relevant departure wake turbulence separation minimum;

(d)         when a VFR aircraft is in flight and is:

(i)            operating directly behind a preceding HEAVY or MEDIUM aircraft; or

(ii)          landing on the same runway as a preceding HEAVY or MEDIUM aircraft; or

(iii)        landing on a parallel runway separated by less than 760 m from the runway of a preceding HEAVY or MEDIUM aircraft;

(e)         when an IFR aircraft is in flight and the pilot has:

(i)            reported the preceding aircraft in sight; and

(ii)          accepted responsibility to follow, or maintain his or her own separation with, that aircraft.

Note: For paragraphs (d) and (e), the pilot in command of the aircraft is responsible for ensuring that the spacing from a preceding aircraft of a heavier wake turbulence category is acceptable. If it is determined that additional spacing is required, the flight crew may inform ATC accordingly, stating their requirements.

10.12.3.4     For a LIGHT or MEDIUM aircraft, ATC must not waive the relevant wake turbulence separation minimum if the aircraft is taking-off after a HEAVY 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:
