What is an essential right provided under airspace rights?

The essential right provided under airspace rights is the right to use all airspace above the surface. This concept is fundamental in property law, particularly in determining the vertical limits of property rights. Airspace rights allow the property owner to control and utilize the space above their property, which includes the use of that airspace for various purposes such as construction of buildings, installation of antennas, or even for aerial navigation.

This right acknowledges the three-dimensional aspect of property ownership, extending not just to the surface of the land, but upward into the sky above it. In many jurisdictions, property rights can include the airspace above the land to a certain height, while also being subject to regulations that govern air traffic and public safety.

The other options do not encapsulate the essence of airspace rights. While the right to own land and the right to build on surface land are important property rights, they do not directly relate to the rights concerning airspace. Similarly, the right to access subsurface resources pertains to mineral rights or subsurface property rights, which is a different aspect of property law and not directly related to airspace considerations.
