I have attached a picture to avoid hijacking. It includes three pilots 2 pilots from one country and third (Special pilot with limited operations) one from another country. The cockpit should be spilt into two different parts. Special pilot cabin should be completely isolated from other pilots but he can observe some of the minimum and very important information. His position will have only one entry point and will not have access to anybody else. I have attached a pic which is a simple pic but tells lot of things.
