In aviation, an air traffic service (ATS) is an extra-ventricular service which regulates and assists aircraft in real-time to ensure their safe operations. In particular, ATS is to prevent collisions between aircraft; provide advice of the safe and efficient conduct of flights; conduct and maintain an orderly flow of air traffic; and notify concerned organizations of and assist in search and rescue operations.
The ATS further provides four services: air traffic control services, which is to prevent collisions in controlled airspace by instructing pilots where to fly; air traffic advisory service, used in uncontrolled airspace to prevent collisions by advising pilots of other aircraft or hazards; flight information service, which provides information useful for the safe and efficient conduct of flights, and alerting service, which provides services to all known aircraft.
An ATS route is a designated route for channeling the flow of traffic as necessary for the provision of air traffic services. This include jet routes, area navigation routes (RNAV), and arrival and departure route. Routes may be defined with a designator; a path to and from significant points; distance between significant points; reporting requirements; and the lowest safe altitude.

“What is lawful is not binding only on some and not binding on others. Lawfulness extends everywhere, through the wide-ruling air and the boundless light of the sky.”
—Empedocles 484–424 B.C., Greek philosopher. The Presocratics, p. 142, ed. Philip Wheelwright, The Bobbs-Merrill Co., Inc. (1960)
“Too much traffic with a quotation book begets a conviction of ignorance in a sensitive reader. Not only is there a mass of quotable stuff he never quotes, but an even vaster realm of which he has never heard.”
—Robertson Davies (b. 1913)
“In the early forties and fifties almost everybody “had about enough to live on,” and young ladies dressed well on a hundred dollars a year. The daughters of the richest man in Boston were dressed with scrupulous plainness, and the wife and mother owned one brocade, which did service for several years. Display was considered vulgar. Now, alas! only Queen Victoria dares to go shabby.”
—M. E. W. Sherwood (1826–1903)
