What is the purpose of any briefing?
One reasonable definition is that a briefing serves to:
verify that the cockpit set-up is as required;
highlight specific threats and how to manage them;
share ones mental model in order to align expectations;
rehearse any specific discrete procedures, e.g. engine-out SID;
agree on possible plans of action in the event of a ‘non-normal’; and
set an open tone that will encourage either crew member to speak up and question any deviation from SOPs or the plan outlined during the briefing.
A good way to achieve the above is to keep briefings short and relevant. The ‘briefer’ should facilitate active engagement of the other party by asking open questions that require the ‘receiver’ to think for themselves.
A good example in the video clip is when the Captain states, “there are no NOTAMS to affect our taxi route” (or words to that effect). A better style would be to ask the First Officer, “which NOTAMS did you see that might affect our taxi route?”
