PA....how often have you landed AND taken off without carrying out the shutdown checklist...!!
I personally never have.And having instructed considerably on at least 6 different types of medium and heavy jets,i can tell you with well placed confidence that the ONLY time that i've done no shutdown checks or pre flight checks
after a landing and
prior to a take off is during touch n go's,which too are passe today in the day of the FFS and zero hour sims.
It seems you've strayed from the chain of thought a bit my friend....
