Superjet passes noise trials
The Sukhoi Superjet 100 last month passed a noise-testing program involving eight certification flights from Italy’s Turin-Cuneo Levaldigi Airport. According to Sukhoi, preliminary results show full compliance with ICAO CAEP IV noise requirements.
The same aircraft, S/N 95004, underwent high-intensity radiated fields (HIRF) testing last month at the same venue. HIRF certification requires that external electromagnetic fields like those produced by a television or radio station or by radar do not affect the function of the aircraft’s electric and electronic equipment.
