Ok, i'll bite. Such as?
Well, maybe every airliner isn't as "busy" as others, but the 747 had a hell of a long checklist just to get to the runway. LONG LIST!! And once in the air its not just flaps up, gear up and fly, with an "after take-off checklist" with 8 items on it. It was quite extensive with "exact" challenge/response callouts we had to give. Corp jets are not like that. Without comparing a 747 and a Learjet checklist side-by-side, from brake release to level off at cruise altitude....................................
Corporate jets, compared to that is a picnic..
