The use of thrust reversers during normal taxi operations and power back operations is?

• A. Required
• B. Prohibited
• C. Optional
• D. Not recommended

Answer: (B)

Thrust reversers are designed to help slow the airplane during the landing roll, not to power movement on the ground. Using reverse thrust while taxiing or doing a powerback can disrupt directional control at low speeds, create a strong reverse airflow that can kick up debris or strike ground equipment, and place unusual or damaging loads on the engines and nacelles. For safety and to protect equipment, the procedures prohibit deploying thrust reversers for normal taxiing or powerback. Hence, the correct stance is that this is prohibited.
