Well this is a discussion forum after all, and just as Nitpicker has pointed out is anyone reading previous posts at all??!! I am no authority at all, but having just done a shiney new Airbus rating I just practised Unreliable Airpeed last week(!), all the alerts are going off left right and centre, with 3 different airspeed indications in the cockpit, so putting TOGA on and pitching up 15deg (sounding familiar yet anyone?!!) you have a manouver which gives you an airspeed that should be at least what you get on initial climbout, then its time to see which speed tape has what you think it should have and compare with the G/S for at least ball park ideal.
