The following nine procedures are general recommendations. Each operator's flight operations manuals will include more specific directions.
Reduce thrust to idle immediately.
Turn the autothrottles off. This prevents the engines from increasing thrust above idle.
Exit the ash cloud as quickly as possible. A 180-deg turn out of the ash cloud using a descending turn is the quickest exit strategy.
Excellent. Have they any suggestions on how to subdue the passengers who've just seen their aircraft enter an ash cloud, the engines lose power and the aircraft "spin out of control...aaarghhh!"
?
