Where is a displaced threshold located?

• A. At a point on the runway other than the designated beginning
• B. At the designated beginning
• C. At the end of the runway
• D. On a parallel runway

Answer: (A)

A displaced threshold means the point where landing begins isn’t at the physical start of the runway. It’s moved to a point somewhere along the runway, so the threshold is located at a place other than the designated beginning. Because of this, the pavement before the displaced threshold can still be used for takeoff runs or taxiing, but not for landing in that direction. The area after the displaced threshold is where landing distance available starts.

So, the statement that describes a displaced threshold best is that it’s located at a point on the runway other than the designated beginning. It isn’t at the official start, isn’t at the end, and isn’t on a parallel runway, which is why those other ideas don’t fit.
