During landing, maximum reverse thrust is prohibited below which speed?

• A. 60 Knots
• B. 75 Knots
• C. 85 Knots
• D. 95 Knots

Answer: (B)

When an airplane lands, thrust reversers are used to help slow down by redirecting engine thrust forward. Their effectiveness depends on air flowing through the engines, which is tied to the aircraft’s speed. Below a certain speed, maximum reverse thrust doesn’t contribute much to deceleration and can even complicate control, so we limit its use to speeds where it’s actually beneficial and controllable. That’s why maximum reverse thrust is prohibited below 75 knots. Above that speed, the reversers provide meaningful deceleration to shorten landing distance and aid braking. Below that speed, pilots normally use idle reverse (or none) and rely more on wheel braking and aerodynamic drag for the final rollout.
