10.12.3         Application

10.12.3.1     Subject to subsection 10.12.3.3, ATC must apply an appropriate wake turbulence separation minimum in all controlled airspace when an aircraft is:

(a)         operating directly behind another aircraft's flight path; and

(b)         at the same level as the other aircraft, or less than 1 000 ft below it.

10.12.3.2     Subject to subsection 10.12.3.3, ATC must apply appropriate wake turbulence separation minima to aerodrome traffic when:

(a)         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
