Moleslayer (and Alf) - I would suggesty that you CAN modify the brief if you feel it enhances safety - in fact that is the Captain's responsibility. To attempt, as PH, to identify a burning engine in minimal vis by looking in would almost certainly result in an excursion, and I need to know BEFORE I stop which way to turn my aircraft, hence PNH should identify the engine. If I am able, I can confirm that, if not, I'll turn as necessary. It is too late when you have stopped straight ahead with a right quarter wind to find out you should have turned to the right!
