It's a bit of a hobby horse of mine and I wanted to discuss that further and make clear my points because I think it's such an important discussion.
Fully agree with you ! I believe some problems arise from lack of proper documentation from BIZJET Manufacturers :
They offer AFM / POH / QRH full of notes for different types of avionic / modifications/installations and lot of AFM supplements.
No FCOM, No Real Check lists and No SOPs available.
Docs are often structured and printed without any regards of Human Factor ICAO standards and the term "checklist" used improperly to indicate "procedures".
Usually the Operator does'nt want any responsability / problems with CAA and copy those " procedures" on a plastic sheet pretending the use as "check list".
Results are long check list full of items not considered "critical" and items often left "to go" during Check List reading (eg. APR armed during take off roll or yaw damper off during landing).
The CAA is happy because it is a Manufacturer Check list !
