A Germanwings Airbus A319-100, registration D-AKNN performing flight 4U-2141 from Moscow Vnukovo (Russia) to Cologne (Germany), was accelerating through about 120 knots for takeoff from Vnukovo's runway 01 when the crew detected the indicated airspeeds on the left hand and right hand primary flight displays differed by about 15-20 knots and further noticed the standby speed indicator was about 40 knots different. The takeoff was continued, during climbout the crew received messages indicating ADR1 and ADR faults. The crew declared emergency, considering the weather at Moscow and other alternatives the crew however decided to divert to Prague (Czech Republic). The aircraft climbed to FL320 and landed safely on Prague's runway 06 about 170 minutes after departure.

Czech's Accident Investigating Institute UZPLN reported in their quarterly bulletin, that maintenance worked the relevant troubleshooting manuals but found no anomalies with the pitot tubes and hoses leading to the air data reference units.
