Sukhoi Civil Aircraft Company (SCAC) has received a Supplemental Type Certificate (STC) which allows the Superjet 100 (SSJ100) to perform reduced thrust takeoff.
Operating with a reduced engine speed and lower turbine gas temperature enables a reduction in engine load and extends engine lifetime, which in turn decreases aircraft maintenance cost. The reduced thrust takeoff mode on the SSJ100 can be used in the airports with runway exceeding 2,000 metres in length.
Tests to certify this oeprating mode were conducted on prototype 95003 in Ramenskoe aerodrome, Zhukovsky, near Moscow. During the tests, 22 flights with different levels of thrust were performed.
A large-scale certification programme has been carried out during 2014 to extend the type’s capabilities. As a result, the Aviation Register of Interstate Aviation Committee (IAC AR) has certified the SSJ100 to perform autoland touchdowns under CAT IIIa, issued a Supplemental Type Certificate (STC) for the expansion of flight operations under RNAV1 and P-RNAV conditions, as well as aircraft operation on narrow 30 metre wide runways.
