Avigation Easement

Definition of Avigation Easement

An avigation easement is a type of property easement usually sought by airport authorities or the Federal Aviation Administration (FAA) to ensure clear and safe flight paths near airports. This easement grants specific rights to use the airspace above private property for aviation purposes, including the right-of-flight over the property, the emission of noise, dust, and other particulates, and access to the land to execute these rights. It also often includes provisions to restrict the installation of certain lights, electromagnetic signals, and bird-attracting land uses that could interfere with aircraft operations.

Avigation easements can be vital for maintaining safety in and around airport zones, as they ensure that the airspace required for safe takeoff and landing is free from obstructions.

Examples of Avigation Easement

Example 1: The Federal Aviation Administration (FAA) pursued an avigation easement to enable planes to overfly private properties situated near the runway approach. This included rights to generate noise, dust, and restrict activities that could interfere with aircraft navigational systems.
Example 2: A municipal airport obtained an avigation easement from neighboring landowners to ensure that no tall structures or hazardous installations appeared within the approach-departure corridor, thereby safeguarding flight operations.
