Why isn't there an explicit SOP to deal with such situation?
Ask the training department?
Then you get''where is that written'' on a line check. Sound familiar?
Aviation is full of deficiencies and especially at airline level. That deficiency is often filled implicitly by the crew's skill and knowledge.They exercise judgement based on?
When they fail to fill this deficiency as some many here have clearly demonstrated in theory, then the airline has no option (due to ass covering) to put it down to pilot error.
For the real answer seek guidance from the Chief pilot and in writing, should you are unable to come up with an answer at the bar!
