Investigators detail Superjet unreliable airspeed incidents

Russian investigators have disclosed further details about a spate of unreliable airspeed incidents involving Sukhoi Superjet 100s at Moscow Sheremetyevo. All 7 incidents involved Aeroflot flights departing the airport on Feb 4-5. The incidents affected 7 different aircraft, according to an air safety bulletin from the Interstate Aviation Committee and transport supervisor Rostransnadzor. Crews of 3 aircraft aborted their take-off roll, at speeds ranging from 70-120kt. Two other aircraft were climbing at relatively low heights of 600-1,200m, when the pilots experienced unreliable airspeed readings. Sukhoi's civil aircraft division had previously defended the Superjet, stating that Sheremetyevo had been subjected to severe winter weather at the time, and other aircraft types had been affected. <br/>
