Coordination with Adjacent Sectors & Units

Standing Agreements

Agreements between Antrim, Talla and Galloway and upper/external sectors are unaffected.

In general:

• agreements for outbounds of (climbing) FL250 will be from ScAC Low to the applicable upper sector, and
• agreements for inbounds of (descending) FL260 will be from the applicable upper sector to ScAC Low.

e.g. ScTMA inbounds via ADN - instead of ScAC North to ScAC South, these would be FL260 level ADN from ScAC North to ScAC Low.

 

Splitting Procedure

The following sectors and units should be informed when ScAC Low is opened:

• All ScAC Sectors
• MPC Northeast
• MPC West
• Newcastle ATC
• All affected Scottish airfield ATC
• Shannon Low
• Dublin ACC
