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.
