The Federal Aviation Administration (FAA) has issued a final rule regarding the airspace around the Tri-County Regional Airport in Lone Rock, Wisconsin. This rule revokes the Class E surface airspace designation at the airport and revises the Class E airspace extending from 700 feet above the ground. The changes are due to the decommissioning of a navigation aid, and they update geographic coordinates to match the FAA's database. The rule is not expected to significantly impact the environment or have major negative consequences.
Simple Explanation
The government's flying helpers changed the rules for airplanes flying near a small airport in Wisconsin. They took away some flying space near the ground because a special helper they used to have is not there anymore, and they made sure everything matches their maps.
