When I did my initial Instrument Rating I remember one of the other students going from Perth (school PH based) to Rottnest Island and shutting one of the Duchess' engines down as part of the training.
They were unable to get the engine restarted and elected to return to PH assymetric. An uneventful single engine landing was completed.
Did the PIC make the right decision? If by returning to PH and saving the company a costly retrieval we might think of the "commercial considerations" and say yes; if they'd crashed we'd all say no.
Is this the dilema which faced Andrew?
