Ok, this is a real question not a joke. What does a pilot do when "nature calls"? Do you leave the cockpit and use the lav like any other passenger? Or is there some other setup?
On a similar note, what are the rules regarding pilots leaving the cockpit during flight? Obviously one person has to be there at all times but are both (or all 3) required to be present for the duration? I really can't think of a good non-emergency reason a pilot would have to leave the cockpit anyway, other than to be relieved at the end of a shift for the long-haulers.
