    An interesting one today. They lost one airspeed indicator, descended back towards Dublin, but got it back working and so headed back on their way.

    Incident: United Boeing 752 near Shannon on May 16th 2015, airspeed indicator failed

    A United Boeing 757-200, registration N19136 performing flight UA-127 from Dublin (Ireland) to Washington Dulles,DC (USA), was enroute at FL320 about 75nm north of Shannon (Ireland) when the crew decided to return to Dublin reporting a technical problem. While descending towards Dublin the crew advised one of their airspeed indicators had failed and they were therefore unable to proceed with their Oceanic crossing, they were still checking whether their landing weight would permit a landing in Dublin or whether they needed the longer runway at Shannon. When descending through FL210 the crew reported they managed to restore their airspeed indicator and thus they were again able to cross the Ocean. The aircraft climbed back to cruise level and continued to Washington where the aircraft is estimated to arrive with a delay of 25 minutes.

    Interesting, was this a MEL issue for the NAT/ETOPs therefore with it restored they could continue ?

    They were descending to Shannon, not Dublin. Interesting to learn what happened.

    They were intending to head to Dublin, they were heading down towards Cork and then gonna turn her around northerly to route in for vectors up to rwy28, she was going the long way to burn off fuel

    Excuse my naivety but why did they continue with the crossing if it had happened once already? Was there not a risk of it occurring again (or at least an increased risk compared to normal)?

    Cloudtops were at around 20,000 ft and about -25 C yesterday so a possibility of some icing in the climb alright. It may have cleared with some pitot-heating and they were satisfied that there was no more danger of it reoccuring in the cruise.
