The priority search sector for Chongxiao airport is an independent sector about 3.04 km from C in the opposite direction.
Reversing the vector from point C to the proposed Nova City airport gives a preferred search sector about 9.5–19.2 degrees east of north and 3.0–3.1 thousand world units from C. The proposal requires at least 3042.189 world units from the other airport and at most 3080.459 from Chongxiao’s own city anchor.

First recorded counterpoint or boundary: Symmetric reflection is only a search heuristic, not evidence that the game's city planning must be symmetric.
Uncertainties and open questions
- Symmetric reflection is only a search heuristic, not evidence that the game's city planning must be symmetric.
- +X=east, +Z=north and 1 unit≈1m have not received official confirmation.
- A second known anchor on the Chongxiao side that can be registered to world coordinates is currently missing, so the sector cannot be precisely projected onto Chongxiao map pixels.
- 3080.459 is a research upper bound based on the Nova City sample, not an officially disclosed airport service radius. Other cities may also have compensating mechanisms such as express rail links.
