Purpose of this change

This proposal is for a Permanent change to the notified airspace design, and the change level is 2C.

In order to facilitate the eventual removal and decommissioning of the LYD DVOR, the LYD 6R/ 5S SIDs from Stansted Airport will be removed. Traffic routeing via LYD will use the DET 1R/ 1S SIDs which are coincident with the LYD SIDs as far as DET.
