Procedural control is a method of providing air traffic control services without the use of radar. It is used in regions of the world, specifically sparsely-populated land areas and oceans, where radar coverage is either prohibitively expensive or is simply not feasible. It also may be used at very low-traffic airports, or at other airports at night when the traffic levels may not justify staffing the radar control positions, or as a back-up system in the case of radar failure.

Famous quotes containing the word control:
“Grown-up people do very little and say a great deal.... Toddlers say very little and do a great deal.... With a toddler you cannot explain, you have to show. You cannot send, you have to take. You cannot control with words, you have to use your body.”
—Penelope Leach (20th century)
