If you decide to keep the engine running with severe vibration, is there a risk of breaking the engine mounts, and losing the engine? That would lead to an impossible c of g situation
Its a hard call lesser of two evils. I didnt determine that the vibrations where too severe to cause engine mounts to break

but decided that with the feel of the aircraft shutting one down would have meant down and only down so kept it going for a while!
As it was things turned out OK as it was the right descision in that particular situation.
When you are in a real situation like that you will know what I mean.
