Special Conditions: Embraer Model 170–100 and 170–200 Airplanes; HighIntensity Radiated Fields (HIRF)

Riepilogo

These special conditions are issued for the Embraer Model 170- 100 and 170-200 airplanes. These airplanes will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The airplane design includes an electronic flight control system as well as advanced avionics for the display and control of critical airplane functions. The applicable airworthiness 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 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. Additional special conditions will be issued for other novel or unusual design features of Embraer Model 170-100 and 170-200 airplanes.
