Sukhoi may deliver Superjet performance mods early

Sukhoi is pressing ahead with modifications to improve its Superjet SSJ100 and may certificate some or all the modifications earlier than the late-2018 timeframe to which it has committed. The drive for an earlier date has been spurred by CityJet, which has a major hub at London City and has ordered the Russian jet. The combination of London City’s short runway and the presence of several high buildings in the nearby Docklands financial area mean that aircraft landing from the west have to adopt an approach of 5.5 degrees, almost double the standard 3 degree glideslope. With that in mind, Sukhoi is developing a modification pack consisting of a new flap setting (‘flap setting 3’), modifications to the braking system software and winglets. <br/>
