Which statement about displaced thresholds is correct?

• A. The displaced threshold indicates the threshold is moved forward; It cannot be used for landing, but can be used for taxiing, takeoff and rollout.
• B. Displaced threshold means landing is allowed on that portion
• C. Displaced threshold arrows guide taxiing only
• D. There is no effect on takeoff distance

Answer: (A)

Displaced threshold means the landing threshold is moved forward along the runway. The pavement before that displaced threshold cannot be used for landing, but it can be used for other operations like taxiing to the threshold and for the takeoff run. In other words, you touch down beyond the displaced threshold, using that forward portion only for takeoff and taxiing rather than for a landing. This is why the statement that the threshold is moved forward, you cannot land on that first segment, and you can use it for taxiing and for the takeoff run is the correct description. The other choices either say landing is allowed on that portion, limit the arrows to taxiing only, or claim there’s no effect on takeoff distance, all of which don’t fit the standard meaning.
