I agree with lomapaseo, crews must deal with the high priority issues before considering alleviations to less likely situations. Much of the discussion has been focused on a fire external to the engine zone, yet aircraft certification has stringent requirements for fire containment and extinguishing; some of these depend on correct crew action.
The Manchester accident was a very rare occurrence, and one single incident should not drive ’vital’ procedures unless the investigation identified major weaknesses. Stopping safely, shutting the fuel off, and evacuating the aircraft are vital actions; they should not be compromised by further restricting the mental processes, already under stress due to the surprising situation, with consideration of wind etc. Note that in the Manchester event, most if not all of the deaths were due to smoke and not fire; the uncontained fire was outside the cabin and only subsequently burnt the aircraft.
Turning into wind is a good safety procedure, but it is a nicety, and thus should not detract from the critical issues of stopping, fuel off and evacuating.
