@amazeifystore: The stall warning went quiet. The aircraft was still stalled. On Air France 447, iced pitot probes disrupted reliable speed readings. When recorded speed fell below 60 knots, the warning system treated angle-of-attack data as invalid and inhibited the alert. Silence didn’t mean the danger had passed.
