Ok so you have a prop failed to feather ,again a well practised and very common sim scenario, in that case why shut down #2 for surging if you are slow? Surging is not a mandatory shut down in a P3 , there are several things you could try to stop the surging Td system , prop govenor , mean while you have either got #1 to feather or set yourself up in a safe flight regime before you bag #2 They had at least 5000 ft so it still begs the question why they ended up slow with 2 engines shut down spinning towards the sea .
