I get up early, to prepare MYSELF for the flight. I do all the homework and treat it like I’m a professional. When I get to the van, I assume my flying partner has done the same. We don’t need to talk about it on the ride to work. We aren’t planning a lunar expedition. We don’t need to prebrief the brief, and then DEBRIEF the brief. Threat and error management, along with good CRM. At some point, if you saturate me with explaining how you fly an airplane….I’m no longer listening to you. Is THAT an effective means of briefing?
