Purpose

Why the need for the Flight Corridor Safety Program?

Removal of the trees will ensure Sea-Tac Airport complies with all Federal Aviation Administration (FAA) regulations protecting the takeoff and landing corridors off the airport runways. These trees, which pose a risk to aircraft safety, are either penetrating the airport’s airspace or soon will grow tall enough to penetrate the airport’s airspace.

  • FAA regulations require airports to identify and manage obstructions to navigable airspace on and around the airport
  • Removal of obstructions helps ensure safe operation of aircraft takeoffs and landings
  • Airports around the country manage similar programs to protect the safety of the flying public
