Final answer:
Enroute area charts for NZ Domestic airspace use the Lambert Conformal Conic Projection, which minimizes distortion for navigational purposes, employing standard parallels at 9°N and 17°N.
Step-by-step explanation:
Enroute area charts used for navigation within the NZ (New Zealand) Domestic airspace are based on the Lambert Conformal Conic Projection. This type of map projection is specifically designed to minimize distortion over certain areas, making it ideal for aeronautical charts where accurate representation of area and shape is important for navigation. The Lambert Conformal Conic Projection for the stated charts uses standard parallels at 9°N and 17°N, which are the latitudes where the scale of the projection is most accurate. The specified scale of 1:12,500,000 means that 1 unit on the map is equal to 12,500,000 units on the ground. The scale helps with determining distances on the map, such as the included 200 and 300 kilometers, which can be used for reference by pilots flying within the region.
