Taiwan's airspace is small, and the planes can end up flying farther north or south as they chase the storm, so they could cross into Japanese or Philippine jurisdictions. But according to international civil aviation regulations, if you want to cross into the airspace of another country, you have to file a proposed flight plan at least ten days in advance.
然而台灣的領空很小，飛機隨便往北、往南飛一點，就闖進了日本及菲律賓的航管範圍；而根據國際民航法規，要飛行至他國領空，至少要 10 天前就提出航線申請。
