The beta range is used for ground operations inclusive of slowing the aircraft after landing. Below flight idle, the power levers control the blade pitch directly. At the power lever ground idle position, blade pitch is such that the propeller produces its minimum level of thrust. By moving the power levers from the ground idle position towards maximum reverse, the propeller blades go into reverse pitch which directs the airflow from the propeller forward which will assist in reducing the aircraft speed during the landing roll or allow for intentionally moving the aircraft backwards.
