The controllers normally work a thirty-six-hour week using radio, radar, electronic computers, telephone, traffic control light, and other devices for communication. Shift work is necessary. Each controller at Airport Control Tower is responsible, at separate times, for giving taxiing instructions to aircraft on the ground, take off instructions and air traffic clearances, and directing landing of incoming planes. These individual duties are rotated among the staff about every two hours at busy locations. At busy times, controllers must work rapidly, and mental detail demands increase as traffic mounts, especially when poor flying conditions occur and traffic stacks up. Brief rest periods provide some relief, but are not always possible. Radar controllers usually work in semi-darkness.
