Making vague and dogmatic assertions is unlikely to yield positive results, (at an event or in daily flying). Explain to the pilots clearly and concisely what you expect. Then expect questions from them. Remember that a question should not be considered an offense. Answer the questions. Converse. Make certain that the numerous parties do in fact understand each other. Be a leader. Leading often entails a certain amount of teaching and patience. Share your understanding with your brothers for you are their keeper.
To walk away in discuss because a question was asked, frankly, would be a failure on the part of the CD.
