The FAA's summary their words, unchanged
These special conditions are being issued for incorporation of an electronic flight instrument system (EFIS) in the Beech Model B300 and 1900D Series Airplanes. These airplanes will have novel and unusual design features when compared to the state of technology envisaged in the airworthiness standards applicable to these airplanes when EFIS is installed. These novel and unusual design features include the installation of electronic displays and the protection of them from high energy radiated electromagnetic fields (HERF) for which the applicable regulations do not contain adequate or appropriate airworthiness standards. These special conditions contain the additional safety standards which the Administrator considers necessary to establish a level of safety equivalent to that provided by the applicable airworthiness standards.
