To improve the coordination between Hong Kong VACC and neighbouring FIRs, Hong Kong VACC holds regular meetings with neighboring divisions and VACCs to discuss and standardize the procedures for handoff and coordination. The result of these discussions are then documented into Letters of Agreement (LOA).
LOA are constantly reviewed and revised so that ATC service can be improved. The latest revision of the LOA are posted here:
