Horses for courses, as someone pointed out. Our company use checklists, tailored for the aircraft and conditions we fly in. Never had any problem in making it a little different to the manufacturers one, in fact we were encouraged to do so, simplifying and making it more relevant. True story. Check flight with CASA for C.P approval. "You going to use a checklist?"was the question. "Well yeah, this one was the reply" What?"That *uckin great big book?"
Well yeah......
"Here, I'll give you one we used to use, based on your manufacturers one. You modify it according to your needs., and give me a look at what you come up with."
Äh ok then."
3 years later, 3 audits, not one NCN.
Sometimes the government is there to help you know, and checklists used the right way are a lifesaver.
