Airspace
Airspace
This domain tests New Zealand airspace classes, control zones and areas, mandatory broadcast zones, special-use airspace, and the radio and clearance requirements that go with each.
Core rules
- New Zealand uses Class A, C, D, E and G airspace. Class A is IFR only. Class C and D require an ATC clearance for both IFR and VFR; ATC provides separation between IFR flights and traffic information to VFR. Class E requires an IFR clearance; VFR aircraft may operate without a clearance but must comply with the applicable rules. Class G is uncontrolled.
- A Control Zone (CTR) surrounds controlled aerodromes; a Control Area (CTA) is controlled airspace above or below. You need a clearance before entering.
- A Mandatory Broadcast Zone (MBZ) requires position broadcasts on the published frequency; it is not an ATC clearance.
- Restricted, danger and military areas may require permission or avoidance. Check AIP NZ and NOTAM.
Worked example
You plan to enter a Class C control zone VFR. Before the boundary, call: 'Christchurch Approach, ZK-ABC, Cessna 172, 10 miles south, request clearance to enter the control zone, landing.' ATC issues: 'ZK-ABC, cleared to enter the control zone, maintain 2,000 feet, squawk 4271.' You read back the clearance, level and squawk. In Class C, ATC will provide traffic information, but you must still see and avoid.
Traps
- Entering a CTR without a clearance because you heard another aircraft cleared.
- Treating an MBZ broadcast as a clearance.
- Assuming Class E is fully uncontrolled.
- Missing airspace boundaries because you used an out-of-date chart.
Airspace
Airspace classification determines whether you need a clearance, radio calls, or both; know the boundary before you reach it.
