A more thorough explanation:

Definition: Air right refers to the legal right to use the airspace above a piece of land or property. This means that the owner of the property has the right to control the use of the airspace above their land.

Example: A property owner who owns a tall building in a city has air rights over the airspace above their building. This means that they can control the use of the airspace above their building, and can prevent others from building structures or flying aircraft in that airspace.

Another example: A homeowner who lives near an airport may not have air rights over the airspace above their property, as that airspace may be controlled by the airport or the government for safety reasons.

These examples illustrate how air rights work in practice. Essentially, air rights give property owners control over the use of the airspace above their land, which can be important for a variety of reasons, such as protecting privacy, preventing noise pollution, or ensuring safety.
