ED Decision 2023/005/R
The probability of instances of simultaneous aircraft movements on the different aerodromes, based on the expected traffic, as well as the impact thereof, should be carefully assessed and taken into account in the local safety assessment before implementing multiple mode of operation.
The management of traffic distribution between aerodromes in multiple mode of operation can be handled at different instances, as follows:
— Strategical: forecasting/pre-planning of traffic flows, planning of staffing and allocation of aerodromes across RTMs
— Pre-tactical: when flight plans are available, building a mental traffic sequence and acting if necessary, e.g. delaying traffic at its origin
— Tactical:
— Normal ATCO working practices, based on existing procedures and own judgement (e.g. delaying start-ups or incoming traffic (by speed reductions, holdings, etc.), while a landing/take-off at the other is handled). It should be noted that AFISOs may not be entitled to use such procedures to the same extent. Although they cannot exercise control of traffic, AFISOs could, under specified circumstances, inform the airspace users of delays or undertake other actions via coordination with other/adjacent ATS units and/or the aerodrome operator/owner.
— Opening additional operational positions (e.g. ground, air), splitting/merging of aerodromes across RTMs, or requesting the support of another ATCO/AFISO.
The ATS provider should establish procedures to manage capacity peaks or high ATCO/AFISO workload for any other reason, e.g. to address when and how to open an additional position in the RTM or when and how to split aerodromes into separate RTMs. All mechanisms implemented should be validated, approved (by the competent authority as part of the change to the functional system) and documented in the operations manual (as specified by Regulation (EU) 2017/373 [4], ATM/ANS.OR.B.035 ‘Operations manuals’).
Note: Guidance on handling of simultaneous aircraft movements at different aerodromes can be found in the SESAR report from the demonstrations/validations performed in Ireland, see reference [38].
Assess simultaneous aircraft movements across aerodromes before multiple mode operations. Manage traffic distribution strategically, pre-tactically, and tactically. Establish validated procedures for capacity peaks, with
