LAHSO acceptance requires which type of guidance?

• A. Vertical Visual or Electronic Guidance
• B. Horizontal Visual only
• C. Instrument landing system
• D. No guidance required

Answer: (A)

LAHSO acceptance hinges on having a defined vertical reference to know exactly where to stop on the runway. Vertical guidance provides that reference, giving a precise descent path or instrument glide path so the crew can determine when to hold short safely. Relying only on horizontal cues or on no guidance leaves too much uncertainty about distance and height relative to the hold-short point, especially in instrument conditions or with higher workload. An instrument approach that includes vertical guidance (such as a glide path) or other electronic vertical guidance meets this requirement, whereas visual cues alone do not provide the necessary vertical reference.
