10.6.5 Application of Time Departure Minima

10.6.5.1 Time departure minima are only applicable during initial climb until reaching the cruising level.

10.6.5.2 Where the planned speed differential between aircraft subject to these departure minima is at or near the minimum prescribed, climbing/cruising speeds must be specified where appropriate to ensure the integrity of the standard.

10.6.5.3 The planned CLIAS notified by GA VFR shall not be amended. The CLIAS of other VFR flights may be altered if agreed to by the pilot.

10.6.5.4 Departure (DEP) Minima 1 to 6 may be applied when:

(a) both aircraft proceed on the same route where a turn of 40 degrees or less is specified; or

(b) the following aircraft’s route involves a turn of more than 40 degrees, the preceding aircraft must continue straight ahead or turn by 30 degrees or less;

(c) when the turn in track is 31 degrees to 40 degrees, Departure standard 5 may only be used if the turning point is defined by a radio navigation aid, or radar is used to observe the turn and ensure the departure standard does not decrease until the aircraft is established on the new track.

10.6.5.5 Departure (DEP) minima 2A, 3A, 4A, 5A and 6A may be applied when both aircraft proceed on the same route on which a turn of 41 degrees to 65 degrees is specified.
