Which Controller do I call for a clearance?

Sometimes there is no Ground or Tower controller online, particulary at some New Zealand provincial airports.

Frequently there are Centre, or what we term Area Controllers online controlling large areas of airspace. So when this occurs who is the best controller to call for a clearance?

The diagram below shows the airspace covered by each Centre Controller. Some things to note are:

  • NZCH-R automatically extends to cover NZCH-B when NZCH-B is not online
  • NZCH-T automatically extends to cover NZOH when NZOH is not online
  • If one sector is not online an adjacent sector may provide ATC however this is not always the case and is up to the individual controller at the time.
