How often is a checklist item answered without the actual condition being confirmed... "clear left/right!... without anyone looking, standard callouts being made without the requisite action being taken that is supposed to be verified/reinforced by the callout
Agree. See it often in the Boeing 737 where the preflight, before start, before taxi and after takeoff checklists have the PM not only doing the majority of the switching but then proceeds to challenge his own actions and responds to his own actions. Makes the true principle of challenge and response a joke. Why Boeing threw out the original challenge by one pilot and response by the other pilot, beats me
