Which term is charted as height above threshold elevation and indicates where to decide to continue or miss on a precision approach?

• A. Decision altitude
• B. Decision height
• C. Final approach fix
• D. Minimum descent altitude

Answer: (B)

On a precision approach, you follow the glide path to a specific height above the runway threshold. That height is called decision height. It marks the point at which you must decide whether you can continue to land using the required visual references; if those references aren’t visible by that height, you execute a missed approach. The other terms describe different concepts: the final approach fix is simply a point on the approach path where the final segment begins; the minimum descent altitude is the lowest allowable altitude on a non-precision approach before you must have the runway environment in sight; and decision altitude is the same idea as DH in some contexts but measured differently, not by height above threshold.
