Thanks reptile,
vilas, a critical aspect of such a scenario is how a failure could occur and then how the crew might detect it.
After identification the aircraft procedures can be followed with appropriate consideration of which system aspects remain and / or are required.
If this type of failure is extremely remote then the value in training might be limited, further still its pointless to read a checklist if the failure has been 'announced' - expected.
The training value in extreme situations is the detection and understanding of the failure and the flight condition, these should lead to the correct checklist. (AF447 followed an inappropriate part of the checklist - failed to understand the situation. What was trained / refreshed to meet the updated regulatory requirement. Who checked if this was done / understood.)
