This Supplemental Type Certificate awarded on 20 June, allows the SSJ100 to land in complicated weather conditions when runway visibility does not exceed 175m, including landing with up to 10 m/s flank wind, with the airport and crews certified to perform flights under CAT IIIa minimum.
Automatic landing system is mandatory to perform Category III operations as visibility is very poor.
Sukhoi proved the reliability and redudancy of automatic landing system through extensive evaluations, under CAT IIIa using all combinations of operating weights and centers-of-gravity, with simulation of crucial engine failure at different segments of descent path and at stiff wind.
The test program was conducted from November 2011 to December 2013, using three test SSJ100 aircrafts. The flight test logged more than 250 hrs and performed a total of 425 automatic approaches.
Another Supplemental Type Certificate in respect to flank wind strength constraints on the runways with poor traction has also been already received.
