Study Requirement Document Confidentiality Classification: Green

RNDSG Action Requirement RAD Restrictions Study 1. NM to run a Network impact assessment of the RAD RNDSG/84 -06 restrictions implemented in the States. (FEB 2015) 2. States to study if some of the RAD restrictions were put in place to balance capacity during a specific period of the year and therefore can be deactivated during the rest.

Content and Analyses Document Confidentiality Classification: Green

Purpose and Scope § RAD restrictions impact on the horizontal flight planning efficiency. § Correlation of two restrictions. § Difference in applying restrictions in planning and actual phase of flight. Document Confidentiality Classification: Green

Tool and Methodology - SAAM / NEST All calculations are done with following baseline and assumptions § § § § AIRAC 1705 SAAM/NEST dataset is used; Traffic: 19 MAY 2017 (34001 flights); No flow regulations; Sectors configurations and capacities are not considered; No military activities; No wind constrains; Improved SAAM Assignment on the shortest distance between city pairs; Only RAD restrictions impacting horizontal trajectory are investigated in a way as they are defined in SAAM, considering how they are described in the RAD document.

Macroscopic Analysis § Percentage of used RAD Pan-European Annex restrictions in SAAM/NEST assignment. § Used restrictions - all RAD Pan-European annex restrictions defined in the SAAM/NEST dataset that have be considered during any of the assignment steps. Not used restrictions - all RAD Pan-European annex restrictions that were not involved in any of the assignment computations. As an average, 6 RADAN restrictions has to be considered per CP (flights on CP EDDM_EGBB have to consider 32 different RADAN restrictions with all braches taken in consideration). § § Document Confidentiality Classification: Green

RAD Restriction Utilization Possible correlation with other RAD restrictions § pivot - by resolving this RAD restriction others restrictions at the same step will be resolved as well § periphery - restrictions that were in the same step as pivot, but were not selected for computation; their conditions were satisfied by resolving the pivot restrictions.

Presentation and Discussion § Internal EUROCONTROL NM distribution in August 2017. § Bi-lateral skyguide - EUROCONTROL NM meeting in Geneva (12 SEP 2017). skyguide has provided EUROCONTROL NM with comments on RAD restrictions used as an example in the document and has requested additional data to proceed with further analysis. § RMG/30 (NOV 2017) with relevant action it was agreed the NRCs, AOs and CFSPs to provide relevant feedback on presented methodology, results and conclusions. § FABEC AOG workshop in Langen (29 JAN 2018), where it was agreed that ANSPs will request and evaluate additional data on RAD utilisation provided by EUROCONTROL NM. § Discussed (but not presented) at the RNDSG/93 (FEB 2018) where several ANSPs expressed their support for this study and requested EUROCONTROL NM to continue with the further elaboration of this study. § Concluded that the “RAD Impact Assessment Study” document to be updated with the new examples and EUROCONTROL NM to continue sharing additional data with ANSP on their request.
