A displaced threshold can be used to provide what safety-related provision?

• A. Safety area dimensions.
• B. Parking area for emergency vehicles.
• C. Extra runway width.
• D. Lighting for night operations.

Answer: (A)

A displaced threshold creates a buffer at the end of the runway by moving where landings can begin. The pavement before that displaced threshold isn’t used for landing, but it can be used for takeoff, taxi, and rollout in certain operations. This setup provides a safety buffer in the approach and departure path, giving pilots additional clearance from obstacles and a defined safety area at the runway end. That’s why it’s described as providing safety area dimensions—the displaced threshold is there to ensure adequate obstacle clearance and safer operations near the end of the runway. The other options don’t reflect what a displaced threshold changes or provides.
