Thrust reversers are more effective at:

Thrust reversers are more effective at:

• A. Low speeds
• B. Medium speeds
• C. High speeds
• D. Idle

Answer: (C)

Thrust reversers work by redirecting the engine’s exhaust forward to create a braking force on the aircraft. The amount of braking they provide depends on how much air is moving through the engine and how effectively that airflow can be redirected. When the airplane is moving fast, a lot of air is flowing through, so turning that flow forward produces a larger decelerating force. As speed decreases, less air is moving through, so the reversible thrust contributes less to braking. Idle or no thrust reversal offers minimal additional braking. So the reverse thrust delivers the strongest braking effect at higher speeds.
