Poor Airbus design if icing comes out to be the reason.
How is it "poor design"? it is the most fundemantal law of Pitot Static system and ASIs
If it did Ice Up, and ASI fell to (near zero), particularly in descent, then the design seems perfect to me
This is taught, certainly at CPL level, but I suspect PPL level as well... Whilst, on a dubious post, I would be reluctant to criticise the crew, 12000'/m down and full power seems to be ringing one or 2 bells to me
