I think this aberdeen incident was due mostly to the fact that the crew used a line up technique that was unecessarely close to the runway edge,along with a static take off not for ice shedding but supposely for a performance issue that was not existant.
The airline was reminded that a static take off doesnt do much for take off perf other than possibly damaging the aircraft the way it did.
Rolling take off (ie take off thrust with brakes released) is recommended.
If i have to ice shed, i will advise pax before push back or if conditions change ,before doing the procedure so they know what is going on.
It may worry first time and regular passengers for different reasons.
