Thank you emratty and Hi_Tech for a much needed dose of knowledge and good common sense. I spent my whole career flying long-haul 4 engine aircraft and totally agree with you.
I remember, on a 747 Classic shutting down an engine because of reducing oil pressure when over Nova Scotia. It was a simple precautionary shut down. We continued to London where the weather was good rather than landing in Canada in winter. In those days there were no data links and it didn't require any discussion with HQ, the decision was obvious and totally safe.
