The FAA's summary their words, unchanged

These special conditions are issued to The Boeing Company (Boeing) for their Model 777-300ER airplane. This airplane has novel or unusual design features associated with single-occupant oblique (side- facing) seats equipped with inflatable restraints. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for occupants of seats installed at an angle of greater than 18 degrees, but substantially less than 90 degrees, to the vertical plane containing the centerline of the airplane, nor for inflatable restraints or related airbag devices. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
