# When both runways are available, the default mode of operations at HKIA issegregated, i.e. one runway is used for arrivals and one runway for departures.# The north runway (RWY 07L/25R) is formally nominated as the landingrunway and the south runway (RWY 07R/25L) is formally nominated as thedeparture runway. Under certain traffic conditions, as determined by ATC,arriving aircraft (Cargo or Passenger) may be directed to the south runway toreduce overall airborne delay.# Independent parallel approaches are not permitted for IFR arrivals. Such that radar separation minima is are not applied in the adjacent ILS approach. Theappropriate in trail spacing should be applied between traffic on final approachto the same runway and the appropriate radar, separation shall be appliedbetween traffic on the final approach to the adjacent runway.
