The FAA's summary their words, unchanged
These special conditions are issued for the McDonnell Douglas Model MD-11 airplane. This airplane will have a number of high technology flight and avionic systems such as, cathode ray tube engine and flight information displays, full authority digital engine controls, and inertial reference systems. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for the protection of these systems from the effects of lightning and the susceptibility to external radio frequency (RF) energy sources, nor do they adequately address the longitudinal stability augmentation system and roll control wheel steering provided by the automatic flight system. These special conditions contain safety standards which the Administrator finds necessary to ensure that critical and essential functions of systems in the MD-11 are maintained.
