RAAF CT4 checklists
Capt Sand Dune
I have heard that part of the reason for the longer-than-need-be (and messy) CT4 checklist is to help weed out those who can't memorise a checklist (considered to be of importance for single pilot ops).
Have heard of flights being terminated at the threshold when checklists can't be recalled correctly ... followed by a very quiet cockpit for the return to ramp.
