Correction.
The plan changed - when Military is not active, Dublin South will control traffic in the R15.
The map has been issued as an AIP ammendment. The new boundaries should be displayed on the EIDW Visual Approach Chart.
As a related issue, the Ryder cup TRA, will be the R15 + an area of the R16 (south of R15) and an area north of the R15 & West of the Weston AOR.
Not sure if this one has been published yet.
