I think it’s important to integrate checklist use into the flow of tasks in the cockpit.
According to the ATSB report the Kingair pilot at Essendon had a similar attitude to people in this thread (checklists are over the top, waste of time, don’t need em). It must feel good to be so wise.
But then he took off with the rudder trim mis-set and everyone died. The checklist could have prevented this.
