Although the aircraft checklist has long been regarded as the foundation of pilot standardization and
cockpit safety, it has escaped the scrutiny of the human factors profession. The improper use, or the
non-use, of the normal checklist by flight crews is often cited as the probable cause or at least a
contributing factor to aircraft accidents.

In all honesty I feel that the checklist has been a detriment to all aircraft types that I have flown so far. In each GA commercial operation that I have had the privledge to be involved in, the CASA approved checklist has been a variation of the manufacturers checklist by the CP at the time.
Most recently, the checklist format of a complex aeroplane has been applied to a basic type within our company. What rubbish! !!!! like this, discourages checklist use because it is superflous.
Why does CASA approve variations of the manufacturers normal checklist to the extent that it does?
