In my company, if you have an engine failiure in a 2 engine aeroplane (thus becoming a single engine aeroplane) you land at the nearest suitable airfield (not continue 100 miles to destination when over head a place like Manch)
(Edited to add)
On the other hand from FL310 you could probably glide from overhead Manch to Dublin
