This page lists the changes that were made to the airspace definitions supplied by the CAA before running them through the airspace converter. Some of these changes are just the removal of airspaces that are of no relevance to hang gliding and paragliding activities. Some changes are to fix inconsistencies in the syntax of the data so that it can be parsed and converted correctly. Some changes are are to fix errors that have be discovered in the airspace definitions.

Control_Areas

NZA 040, NZA 041, NZA 149

The airspaces were removed because they cross the antimeridian and are not handled correctly by the Garmin and Google Earth software. They are not useful for hang gliding and paragliding purposes anyway.

NZA 143

Added "anticlockwise" to the last arc so that it reads:

"S 36 43 25.6, E 175 02 17.5, the arc of a circle of 20 NM radius centred on
S 36 47 12.5, E 174 37 52.4 (Whenuapai VORTAC) from
S 36 43 25.6, E 175 02 17.5 anticlockwise to
S 36 36 36.6, E 174 58 57.3 (transponder mandatory). "

NZA 145

Changed "S 38 54 22.7, E 176 47 43.0; the arc of a circle, 33 NM radius, centred on "
to "S 38 54 22.7, E 176 47 43.0; the arc of a circle of 33 NM radius centred on ".

Added a ";" to the end of the first arc i.e.
"S 39 05 55.3, E 176 19 39.8; a line joining" .

NZA 340

Changed "S 39 05 55.3, E 176 19 39.8; the arc of a circle, 33 NM radius, centred on "

to "S 39 05 55.3, E 176 19 39.8; the arc of a circle of 33 NM radius centred on "

NZA 341

Changed "S 177 45 18.8" to "E 177 45 18.8"

NZA 637

Deleted the struckout text.

NZA 657

Added the ";" to
"S 41 34 05.7, E 172 57 22.0; a line joining "

NZA 735

Deleted the struckout text.

NZA 841

Removed the ";" from
S 43 49 05.5, E 172 21 38.5; clockwise to

General_Aviation_Areas

NZG 271

Changed this...
"All that airspace bounded by a circle of 0.41 NM (0.75 km) radius, centred on
S 37 37 49.3 E 176 10 18.9. "

to this...
"All that airspace bounded by a circle of 0.41 NM radius centred on
S 37 37 49.3, E 176 10 18.9. "

NZG 275

Refactored this into two sectors as in NZA 633 so that it could be parsed correctly.

Mandatory Broadcast Zones

NZB 273

Changed this...
All that airspace bounded by a circle of 3 NM radius, centred on

to this...
All that airspace bounded by a circle of 3 NM radius centred on

NZB 374

Added "by" to the first line...
All that airspace bounded by...

NZB 682

Removed the "," after 'radius".
