Calm down everyone.
This
is the Tech Log so it's perfectly reasonable to ask questions whether or not such information is available elsewhere.
The manuals generally do not give detailed explanations for non-normal procedures and training departments are generally primarily/solely interested in recurrent training, checking and recruiting.
LCC have nothing to do with this. I know of countless former LCC pilots who were eagerly recruited by the legacy carriers and former charter airlines. Most pilots have learned their basics in the same FTOs anyway.
However, those asking questions ought to show humility when talking to their peers.
As for the actual point raised: I suspect McBruce is right. I'd only add that controllability and stall margins undoubdtedly favour a higher speed and
less tampering with the configuration.
