Preliminary Data Shows Full Compliance With ICAO CAEP IV Requirements

Under supervision of AR IAC and EASA, the SSJ 100 has successfully completed the noise testing program performed as a part of the overall certification process. The aircraft made eight certification flights at the Cuneo-Levaldigi airport, and the preliminary results show that the aircraft noise levels are in full compliance with ICAO Committee on Aviation Environmental Protection (CAEP) IV requirements.

After being cleared by AR IAC and EASA, the same aircraft, #95004, is undergoing HIRF testing at Cunea-Levaldigi. The HIRF certification is required to demonstrate that the aircraft's electric and electronic equipment is not influenced by external electromagnetic fields, such as radio or television broadcasts and radar. HIRF testing requires exposing the aircraft to RF at frequencies and levels set by certification rules. The aircraft can be electrically powered or unpowered, and its engines can also run during the test. The electromagnetic fields and currents on cables inside the aircraft are measured during during the RF exposure, and avionics equipment is monitored for any malfunction. Remote telemetry is used to monitor aircraft parameters in real time as well in order to keep workers from being exposed to radiation during tests with powered aircraft.

"Sukhoi Superjet 100 is the first aircraft in Russia that has compliance with international noise standards proven in flight under supervision of Russian and European certification authorities," said Igor Vinogradov, SCAC's SVP on Certification, commenting the finalization of the noise testing program.
