Sukhoi Civil Aircraft (UAC, Stand J39, Chalet CS48) has brought to Singapore its Superjet SSJ100, equipped with so-called saberlets—wingtip devices meant to improve takeoff and landing performance and decrease fuel consumption by at least 3 percent.
Part of SCAC’s Superjet 100 improvement program, the retrofitable saberlets will cut the cost of operating each airplane by as much as $70,000 per year, according to SCAC president Alexander Rubtsov.
