TAG, bird strike is a possibility but don't forget the engines have the "chip baskets" in front of them so unlike fixed wing, the engines are less vulnerable and travelling much slower. Also, taking out 1 engine shouldn't bring it down.
TLN - moving map? Well worth spending lots of dosh on to show a big screen of blue north sea! Anyway lots of airframes now have EGPWS map displays, and Nav displays showing waypoints and navaids. Can you explain what contribution a moving map display would bring to the party?
