'Before TAKE OFF checklist to the line'
'Before TAKE OFF checklist to the line complete'
'Cabin secure for TAKE OFF'
'Before TAKE OFF checklist below the line'
'Before TAKE OFF checklist below the line complete'
In our (mostly standard Airbus) SOP's the word takeoff is mentioned explicitly five times before we get the actual take off clearance. The company tries to mitigate this by adding 'line up only' or 'take off confirmed' after the last checklist...but that seems to me like putting the horse behind the cart.
