TOCW check.
Question to Mad Dog or any other pilots..do you always
a)perform functional check ie.preflight check with parameters out of limits so warning sounds OR
b)perform nuisance check..during taxi after configuring,quickly advance TL to ensure you wont have to abort OR
c)both
Also,do you see the check in (a) as mandatory before every takeoff and whether or not it can be performed by either pilot.Thank you for your answers.
