Superjet Gets Cat III Cert

Russia’s Aviation Register of Interstate Aviation Committee (IAC AR) issued a supplemental type certificate in late June that allows the Sukhoi Superjet 100 to execute Cat IIIa automatic landings.

This STC allows the SSJ100 to land at Cat IIIa-certified runways when visibility does not exceed 175 meters and when the crosswind component does not exceed 10 meters per second (19 knots).

Sukhoi Civil Aircraft performed tests to evaluate the SSJ100’s automatic landing characteristics at various combinations of operating weight and center-of-gravity, as well as simulated engine failure at different points of the glidepath and in a brisk crosswind.

Sukhoi said three aircraft flew 425 automatic approaches during 250 hours of testing between November 2011 and last December.
