There were the checks they do before starting the engines, before pulling away from the gate, before taxiing to the runway, and so on. In all, these took up just three pages. The rest of the handbook consisted of the “non-normal” checklists covering every conceivable emergency situation a pilot might run into: smoke in the cockpit, different warning lights turning on, a dead radio, a copilot becoming disabled, and engine failure, to name just a few. They addressed situations most pilots never encounter in their entire careers. But the checklists were there should they need them.
