The FAA's summary their words, unchanged
These special conditions are issued for approval of the Boeing Model 777 airplane for Extended Range Operation with Two-engine Airplanes (ETOPS) without the prerequisite service experience currently required for ETOPS approval. The manufacturer has requested that the Model 777 airplane be found to be acceptable for ETOPS operation at the time of type certification. Extended range operation of twin engine airplanes is not envisioned by the airworthiness standards for transport category airplanes, and has been determined to constitute a novel of unusual feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that provided by the airworthiness standards for transport category airplanes.
