What I was alluding to was not the use of checklists (a topic that could occupy a Masters Dissertation!) but the fact that the flight crew carry out briefs, and that much of the content will also be familiar to them. Doesn't mean they are not carried out, albeit that on a multi sector day, once the a full brief has been given it may be acceptable to refer to "standard brief" for that particular phase, within the same crew.
Not only is a brief given, but questions are also asked (depending on company SOP) e.g. Capt to F/O "what will be your actions in the event of an engine failure prior to V1."
Anyway, sorry - as professional pilot - to try and tell pax how they should respond to safety briefs. I'll continue to listen to them and make damm sure I know what my actions will be, when I'm travelling as pax (which is pretty frequently)
