De facto ... As I said I'm talking about 100 or 129 ft difference and not 1000 ft difference (read my 1st post please ) .... In aviation and more specifically in abnormal situations ... We must THINK and analyse our current status as abnormal and emergency procedures cover about 95 to 99 % of the possible scenarios but not every particular case with any unpredictable factor (multiple failures etc) .If you apply only the theory and you don't adjust your theory knowledge + your skills to the rest 5-1 % you may end to a disaster ...
Don't forget ... After some incidents the abnormal / emergency procedures may change and follow the "non standard actions" of the crew involved if proven more efficient than the current procedure
My answer is not a guideline as you said but just an answer about the initial question... We must have a practical way of thinking ....
