The Air Boss is the Almighty on an aircraft carrier, controlling just about everything aviation-related on the ship and in the immediate vicinity.
This is the placard that he reads from into the flight deck/ship announcement system (called the 1MC) to let everyone on the flight deck and throughout the ship know that its time to get ready to go flying.
Anyone who has spent time on an aircraft carrier flight deck has heard this, and if you put on whatever voice of authority you have and read this aloud, you TOO can be the Boss!
