This dataset identifies hazard levels associated with aircraft flight routes across KwaZulu‑Natal. It integrates weighted air‑route classifications, airport influence zones, and elevation‑based risk modifiers to quantify spatial variations in aviation‑related hazard. Corridor‑level hazard ranks (1–10) were applied to commercial, regional, general‑aviation, and helicopter flight paths. |
