Chart Reading

When it comes to using and reading Visual Navigation Charts (VNC), you must be sure that it is a current version.  

Changes to a VNC such as alterations to airspace, frequencies, hazards and obstacles, etc, can occur yearly.

Interpret the features and symbols of a NZ Aeronautical Chart.

Common Frequency Zone (CFZ). 

Common Frequency Zones are surrounded by a line of diamond shapes.

They have been established to encourage pilots to use a single VHF frequency specified for the zone.

Pilots should transmit their position, altitude and intentions relevant to prominent reporting points or features at entry, or at other times for traffic safety.

CFZ are not mandatory and are advisory in nature.

Vertical height limits and the frequency are located in a blue box.

Visual Reporting Points

Visual reporting points

• are a blue and clear diamond shape at the end of a straight line.
• are based on prominent geographical features; and
• are identified by names or designators that—
  • are easily recognisable in voice communications; and
  • will not be confused with those of other reporting points in the same general area; and
  • do not create confusion with other communications exchanged between pilots and between air traffic services and pilots.
