AMC10 ATS.TR.210(c)(2)(i) Operation of air traffic control service
ED Decision 2020/008/R
PROCEDURAL
CONTROL — MINIMUM SEPARATION BETWEEN DEPARTING AIRCRAFT
(a) The aerodrome air traffic controller should apply a 1-minute separation if aircraft are to fly on tracks diverging by at least 45 degrees immediately after take-off so that lateral separation is provided (see Figure 34).
(b) When:
(1) aircraft are using parallel runways; or
(2) in a context of operations on diverging runways which do not cross, the pilot has accepted a take-off direction which is not into the wind, in accordance with the procedure described in point (b) of GM1 ATS.TR.260,
this minimum may be reduced, provided instructions covering the procedure have been established by the air traffic services provider and approved by the competent authority and lateral separation is effected immediately after take-off.

(c) The air traffic controller should apply a 2-minute separation between take-offs when the preceding aircraft is 74 km/h (40 kt) or more faster than the succeeding aircraft and both aircraft will follow the same track (see Figure 35).

(d) The air traffic controller should apply a 5-minute separation while vertical separation does not exist if a departing aircraft will be flown through the level of a preceding departing aircraft and both aircraft propose to follow the same track (see Figure 36). The air traffic controller should take action to ensure that the 5-minute separation will be maintained or increased while vertical separation does not exist.
