There is some truth in the theory that you should only use a checklist when you know the checklist.
I stand to be corrected but I believe that was the RAF way
A strange comment maybe but with an element of truth.
The point that you are likely to miss something is usually the very time that you are under a lot of pressure, in bad weather, turbulence or your attention else where. I am talking single pilot.
Its hard to read a checklist single pilot at night in bad turbulence when you are flying a challenging approach and your hands and concentration are full
I have even known of one pilot in such conditions who dropped the checklist which lodged out of sight beneath the seat so learn the checklist and the aircraft till you know it blindfolded. Then the checklist becomes a confirmation not a fly by numbers manual
Multi crew is a different ball game
