Public Transport Landing Factor
Something was brought to my attention when converting onto a new type earlier this year that the 1.43 public transport safety factor is only relevant at the planning stage. Once airborne this goes out the window so to speak and you no longer need to apply it.
My question is why can we disregard this once airborne? I get the point that you may have to be more flexible when airborne due changing circumstances, abnormal procedures etc but that's the case with many other things too and why we can operate outside of SOP's when it can be justified of course. Maybe I'm over thinking it and should just accept it as it is but just wondered if anybody else has any ideas on this performance subject?
