Maybe the ground /air sensor
I remember the accident in Madras with one of the first 320's delivered to Indian Airlines. I believe the towback truck sheered the wiring on the nose strut of the ground/air sensor. The acft. ended up with its nose in the terminal .
I think there could be a clue. Maybe the Alpha floor protection sensed a in flight condition with zero IAS and commanded the engines to GA thrust. I never flew an Airbus , but I'am sure many of you pilots out there know the logics of this machine. Q. Do the brakes get signals from the ground/air sensor. Could it be they had a T/O warning as the flaps were up and somebody tripped the ground/air cb to silence the warning. I realise there are a lot of maybe's and if's , but it could be a good starting point.
I like to hear your comments on this.
Good Flying!
