The concept of a displaced threshold is intended to ensure safety and compliance with which needs?

• A. Obstructions, noise abatement, and safety area requirements.
• B. Passenger comfort and aesthetic appeal.
• C. Fuel supply and storage.
• D. Terminal road traffic control.

Answer: (A)

A displaced threshold is used to protect safety around the runway by ensuring landing touch-down occurs at a point that provides enough obstacle clearance and complies with required safety areas. When the threshold is displaced, the portion of runway before it isn’t used for landing, but it can still be used for takeoff and taxi operations. This setup helps accommodate obstructions in the approach path and meet safety area requirements, and it can also support noise abatement objectives by altering where landings occur relative to sensitive areas. That’s why this concept is tied to obstructions, noise abatement, and safety area requirements.
