Sukhoi Civil Aircraft Company received a Supplemental Type Certificate, which allows Sukhoi Superjet 100 to perform reduced thrust takeoff.

Operating mode with engines working with a reduced engine speed and lower turbine gas temperature allows to reduce engine load and to extend engine lifetime, so this, in turn, minimizes aircraft maintenance cost.

Reduced thrust takeoff mode on Sukhoi Superjet 100 aircraft can be used in the airports with runway exceeding 2000 meters in length.

Being a part of Sukhoi Superjet 100 aircraft development program, tests have been conducted on a prototype 95003 in Ramenskoe aerodrome, in Zhukovsky, near Moscow. During the tests, 22 flights with different levels of thrust have been performed.

Sukhoi Civil Aircraft Company constantly works on expanding operating conditions of Sukhoi Superjet 100 aircraft and improving aircraft type design.

A large-scale certification program has been carried out in 2014, and as a result, the Aviation Register of Interstate Aviation Committee (IAC AR) has confirmed the possibility of SSJ100 aircraft to perform autoland under CAT IIIa. IAC AR has also issued Supplemental Type Certificate for expansion of operating conditions regarding performance of flights under RNAV1 and P-RNAV, crosswind limitation on runways with low Mu-factor, as well as regarding aircraft operation on narrow 30-meter-wide runways.
