Every aeroplane has checks, whether you memorise them, or write them down in a list, there is always a Check List.
The RAF make student pilots remember all of their checks; however, the average PPL does not fly frequently enough for them to memorise and retain all of this information. Consequently, the Check List is the norm and forms part of a schools standardisation.
Pilots should not be reading a Check List in the circuit, all important checks should be memorised. Less important items and subsequent actions are better carried out from a check list to ensure they are correct. How often do you have an alternator failure and is it reasonable for low houred pilots to memorise infrequent emergency drills?
Back to the original thread, there is no examination requirement that necessitates a pilot making a check list!
