What is a displaced threshold?

• A. A threshold located at a point on the runway other than the designated beginning of the runway.
• B. A threshold located at the designated beginning of the runway.
• C. A threshold used only for taxiing.
• D. A threshold that cannot be used for takeoffs.

Answer: (A)

A displaced threshold means the starting point for landings is moved forward from the physical beginning of the runway. The pavement before that point exists, but it isn’t used for landing; it may be available for taxiing or for takeoffs, depending on markings and procedures.

That makes the statement describing a threshold located at a point on the runway other than the designated beginning the right one. The other options describe a standard threshold, or misstate how the area before the displaced threshold is used (it isn’t limited to taxiing only, and it can be used for takeoffs in many cases).
