An aviation easement is a stipulation that restricts owners of properties situated near an airport from having structures or trees that exceed a certain height. Aviation easements exist to maintain the safety of both residents near an airport as well as the safety of the aircrafts that fly into the airport. Having height limitations guarantees that aircrafts will not encounter an unforeseen object when arriving or departing from the airport. The aviation easement usually provides the exact limitations that property owners need to follow. If buyers are interested in buying a home near an airport, they may consider asking about any aviation easements that are in effect. Determining what limitations one will have if he or she purchases the property can help decide whether or not to make the purchase.
