Thanks for the inputs. So, we still do not have a clear-cut reason for this action.
I suppose will just have to follow the recommendation of the Ops Liaison Meeting. However, it is quite unlikely that spoilers are left in the out position after ldg; aircraft is taxiied in and switched off; then it is started up ( with the spoilers still in the out position) and taxiied out and now when the Auto brake is armed the aircraft comes to a screeching halt.
