Russia’s Aviation Register of Interstate Aviation Committee (IAC AR) has issued a Supplemental Type Certificate (STC) confirming the capability of the Sukhoi Superjet 100 to execute automatic landing under CAT IIIa ICAO.
The STC allows SSJ100 landings in complicated weather conditions when runway visibility does not exceed 175 metres, including landing with up to 10 m/s cross wind, when the airport has the respective certification and crews are certified to perform flights under CAT IIIa minima.
Sukhoi Civil Aircraft Company (SCAC) successfully performed a wide range of tests to evaluate the SSJ100’s characteristics in respect of CAT IIIa automatic landing using all combinations of operating weights and centres-of-gravity, with simulation of crucial engine failure at different segments of descent path and in stiff winds.
Total test programme between November 2011 and December 2013 exceeded 250 hours and involved three test SSJ100s. The total amount of automatic approaches during performance of flight tests amounts to 425.
Another Supplemental Type Certificate, widening the operational scope of SSJ100 in respect of cross wind strength constraints on runways with poor traction has also been already received.
