What is another word for airspace?
Pronunciation: [ˈe͡əspe͡ɪs] (IPA) 
A foreign term to some ears, "airspace" is the area above and around the earth that is used by aircrafts and monitored by air traffic control. Synonyms for this term are "flight zone," "aviation area," and "flying space." Regions of the air that are designated for use by certain types of aircraft are referred to as "flight corridors," "flight lanes," or "air routes." The specific height and range within an airspace can be identified using "flight levels" or "flight layers." Some areas of airspace may also be reserved for military use, designated as "military airspace" or a "restricted flying zone." Regardless of the terminology used, it is essential to observe airspace regulations and restrictions to maintain safety and efficiency in air travel.
