Sponsor: Stansted Airport

Following very positive feedback and support during an extensive trial, Stansted Airport proposes the permanent introduction of the two trialled RNP1 SIDs, CLN1E and DET1D to complement the existing conventional procedures. The two procedures will reduce the number of people in the local area directly overflown by departing aircraft as a result of improved navigational accuracy.
