10. Coordination Principles

Question 1

Give full details of the methods that may be used to achieve coordination (TACTICAL)?

Answer 1

Tactical Co-ordination.
The co-ordination of individual aircraft to which the co-ordinating controllers are providing, or are about to provide, an ATS. It is achieved either verbally (face-to-face or over a landline) or silently using an electronic data communication system. Silent co-ordination procedures are to be detailed in the MATS Part 2 and Unit Military Procedures.

Question 2

Give full details of the methods that may be used to achieve coordination (STANDING)?

Answer 2

Standing Co-ordination.
Co-ordination which is implemented automatically, on a permanent basis, without communication between the controllers involved. It is effected in accordance with a written agreement between the units or sectors involved, and is only valid for the aircraft and circumstances specified in the MATS Part 2.

Question 3

When is coordination deemed to have been achieved?

Answer 3

When approved by the CAA, co-ordination is deemed to have been achieved if an estimate message has been passed and the accepting ATC unit has raised no objection.
