During approach and landing , the flying pilot should be guarding the controls and ready to take over any time , flying is an attiude and flying during critical stages of the flight needs more attention and good lookout, I've been watching pilots sitting x-legged and hands on top of each on chest , and many behaviours like looking for something in their briefcases relying on automation , removing their feet from rudder pedals.It does not look good and may be only one day in your life you'll find out it is very important.
