A Contingency Hazard Area (CHA) refers to specific sections of airspace that are designated and managed by air traffic control prior to a launch or reentry operation. These areas are established in advance and are activated if there is a failure during the operation. This definition comes from the U.S. Federal Aviation Administration’s Aeronautical Information Manual, specifically the Pilot/Controller Glossary. The purpose of a CHA is to ensure safety by providing a clear protocol for managing potential hazards. By understanding these areas, pilots and air traffic controllers can work together effectively to handle emergencies and protect both people and property.
