9F. Departures
9F.1 Wake turbulence separation minima on departure shall be applied by measuring airborne times between successive aircraft. Take-off clearance may be issued with an allowance for the anticipated take-off run on the runway; however, the airborne time interval shall reflect a difference of at least the required time separation.
9F.2 The wake turbulence separation minima in the table below shall be applied when aircraft are using:
(1) (2)
the same runway; or
parallel runways separated by less than 760 m; or

Section 1: Chapter 3: Separation Standards - Page 13
CAP 493
Table 4:
(3) crossing runways if the projected flight path of the second aircraft will cross the projected flight path of the first aircraft at the same altitude or less than 1000 ft below; or
(4) parallel runways separated by 760 m or more, if the projected flight path of the second aircraft will cross the projected flight path of the first aircraft at the same altitude or less than 1000 ft below.

Note: ATC shall apply the minima as prescribed above, irrespective of any pilot request for reduced wake turbulence separation. ATC does not have the discretion to reduce wake turbulence separation minima.
