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.
Independent parallel runway departures require specific conditions. Runways must be at least 760m apart with diverging departure tracks (15 or 10 degrees with RNAV/RNP). A surveillance system identifying aircraft within 1.9km of the runway end is mandatory. Air traffic control procedures must guarantee track divergence for safe parallel operations.
