Question #114:

If there was an unruly passenger on board, how could pilots remedy the situation? Paraphrase: Imagine there is an aggressive passenger on board. Flight attendants ask for your help. What would you do?

Answer:

In this situation flight attendants are responsible for solving this problem, and if it doesn’t help, pilot will make an announcement by passenger addressing system to this passenger about penalties upon arrival. In worst cases the flight attendants should restrain this person and pilot should perform priority landing, advice ATC and call police upon arrival.
