AR IAC and EASA have cleared Sukhoi Superjet 100 for noise testing certification flights

On completion of 5 validation flights Sukhoi Superjet 100 has been cleared by AR IAC and EASA for noise program certification flights. At the Levaldigi airport SSJ100 is performing certification flights. Thanks to a telemetry equipment interfacing with on-board Aircraft testing instrumentation, the noise relevant flight parameters, including the aircraft trajectory, will be shown in real-time to flight test specialists sitting in Alenia Aeronautica Control Room located in Torino Caselle airport. Subsequent to the flight, the data will be analyzed in the same Alenia laboratories to provide quick look assessment of aircraft noise characteristics. Since meteo data are essential for Noise tests, both on-ground and in-flight measurements will be taken during tests, the last by using an helicopter equipped by a special probe.

Prior to the clearance AR IAC and EASA verified the aircraft 95004 configuration, reference trajectories for noise certification, flight test procedures, flight and ground test instrumentation and calibration status. In course of AR IAC-EASA parallel certification, EASA experts have already taken part in high angles of attack program, airstairs ejection and hydraulic system pressurization checks.

"SSJ100 Noise and HIRF testing, conducted in Italy is not just a program which tests certain aircraft parameters, it's an essential part of a big effort of AR IAC and EASA in harmonization of the certification standards of Russia, CIS and Europe. And this job is made possible owing to Sukhoi Superjet 100 Program, as SSJ100 is the pioneering aircraft which is designated for the both Russian and world market and has to meet the international certification norms", - said Igor Vinogradov, SCAC's SVP on Certification.
