The Flick -- A term used by air traffic controllers to describe a mental model representing the current and future positions of air traffic in a section of airspace. Controllers visualize the paths of multiple aircraft in terms of position, altitude, trajectory and speed. Controllers also refer to this as "having the picture." But the picture moves -- like a movie -- hence the term “the flick.”
