AMC1 ATS.TR.255 Operations on parallel or near-parallel runways ED Decision 2020/008/R REQUIREMENTS AND PROCEDURES FOR INDEPENDENT PARALLEL DEPARTURES (a)       Parallel runways may be used for independent instrument departures as follows: (1)       both runways are used exclusively for departures (independent departures); or (2)       one runway is used exclusively for departures while the other runway is used for a mixture of arrivals and departures (semi-mixed operation); or (3)       both runways are used for mixed arrivals and departures (mixed operation). (b)       Independent IFR departures should only be conducted from parallel runways when the conditions listed below are met: (1)       the runway centre lines are spaced by a minimum distance of 760 m (2 500 ft) (as also specified in CS ADR-DSN.B.055 ‘Minimum distance between parallel instrument runways’ in EASA ED Decision 2014/013/R ‘Certification Specifications and Guidance Material For Aerodromes Design’, as amended); (2)       the nominal departure tracks diverge by at least: (i)        15 degrees immediately after take-off; or (ii)       10 degrees where: (A)      both aircraft are flying an RNAV or RNP instrument departure; and (B)       the turn commences no more than 3.7 km (2.0 NM) from the departure end of the runway; (3)       a suitable ATS surveillance system capable of identification of the aircraft within 1.9 km (1.0 NM) from the end of the runway is available; and (4)       ATS operational procedures ensure that the required track divergence is achieved.
