Special Conditions: Boeing Model 747-200 (E-4B) Series Airplanes; High Intensity Radiated Fields (HIRF)
Special conditions are rules the FAA writes for one design when the standard certification rules do not cover something new about it. These were published May 1, 2000 for S.I.P. Technical Services, covering the 747-200 (E-4B). System: instruments and avionics.

The FAA's summary their words, unchanged
These special conditions are issued for Boeing Model 747-200 (E-4B) airplanes. These airplanes, modified by S.I.P. Technical Services, Inc., will have novel and unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The modification incorporates the installation of a new Flight Management System (FMS) and an Electronic Flight Instrumentation System (EFIS). The applicable regulations do not contain adequate or appropriate safety standards for the protection of these systems from the effects of high-intensity radiated fields (HIRF). These special conditions provide the additional safety standards that the Administrator considers necessary to ensure that the critical functions that this system performs are maintained when the airplane is exposed to HIRF.
