U.S. Controllers Can Use Radio, Books to Be Alert, FAA Says

U.S. air-traffic controllers can listen to radios and read to help stay awake during overnight shifts, the Federal Aviation Administration said.

The agency for now is keeping so-called 2-2-1 schedules that allow controllers to work two evenings, followed by two day shifts and an overnight period, which a U.S. safety board has said runs counter to normal sleep-wake patterns.
