The FAA's summary their words, unchanged
These special conditions are issued to West Star Aviation, 796 Heritage Way, Grand Junction, CO 81506, for a Supplemental Type Certificate for the Cessna 441 Conquest. This airplane will have novel and unusual design features when compared to the state of technology envisaged in the applicable airworthiness standards. These novel and unusual design features include the installation of an electronic flight instrument system (EFIS) in the form of two digital altimeters. The digital altimeters will be Honeywell/Ametek AM-250 models, one on the pilot side and one on the copilot side, for which the applicable regulations do not contain adequate or appropriate airworthiness standards for the protection of these systems from the effects of high intensity radiated fields (HIRF). These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to the airworthiness standards applicable to these airplanes.
