Extended Operations

Extended Operations

Extended Operations (ETOPS) allows twin-engined airliners to fly long-distance routes that were previously off-limits to twin-engined aircraft, as defined by the U.S. Federal Aviation Administration. Boeing has been a driving force of ETOPS, having recognized its many advantages early on by making safer, more reliable, more efficient airplanes that are approved for the maximum levels of ETOPS. Boeing supports airline Extended Operations by providing technical documents, guidance material, and training that assist airlines with every aspect of their ETOPS programs, including flight operations and maintenance.

Configuration, Maintenance, and Procedures (CMP) documents contain all the requirements for a given airplane model for type design (configuration), maintenance, and operational procedures as stipulated in Federal Aviation Administration's (FAA) ETOPS regulations. These model-specific documents are created by Boeing and are approved by the FAA, who technically owns the documents.

Boeing issues a quarterly ETOPS report, widely distributed in the industry, covering the following topics:

  • ETOPS type design approval status of all Boeing models
  • ETOPS operational approvals (airline approval dates, levels, airplanes)
  • Worldwide airplane/engine In-Flight ShutDown rates
  • Counts of ETOPS operations by operator, model, and area
  • ETOPS diversion and air tumback rates by model
  • Graphs by cause category of problems on ETOPS flights
  • Categorized details of ETOPS flights with engine failures
  • Graphs of industry trends of all scheduled flights in different areas of the world
  • Fleet information of all operators of Boeing 737, 757, 767, 777 and 787 models;
  • Other statistical information pertaining to ETOPS
