Up to 447, momentary loss of airspeed data had occurred in thirty-one other A330 a/c, all of which landed uneventfully with a log-book entry made.
Nothing changes regarding actual a/c velocity with loss of ”indications” of velocity. If Bonin had done nothing, this almost certainly would have been just another logbook entry.
Revisiting the accident with a view to theorising or even just offering observations first requires the respectful familiarisation with the substantial public record here and elsewhere, all available data from the recorders and the entire range of BEA work accomplished.
