Catabolic IBS
I don't have access to the Ryan Ops manual (I assume its that to which your refer?) but it is certainly not in my company's ops manual or any of the other rather numerous airlines I have worked for. Also my post did refer to all airline managers not just Ryan's.
Are you saying the manual states that crews must not heed any such threats? That would greatly surprise me but if indeed it is in Ryan's manual and exactly as I said (or near enough in exact meaning) then I would agree with you.
