The only relation this incident has to AF447 is that the aircraft was an A332 and UAS was due to ice in the static port. A stall warning did not enter the equation, but similar warnings were generated. The crew followed the QRH and the graphic below shows the outcome.
The dip in altitude is not real, and for an explanation see the
ATSB Report.
NB The graphic above is larger than that published in the report.
