Night LAHSO is allowed only when which conditions are present?

• A. Hold-short lights and vertical guidance
• B. PAPI lights are available
• C. Full moon conditions
• D. No electronic guidance

Answer: (A)

Night LAHSO requires a clearly identifiable hold-short point and reliable guidance to ensure you can stop precisely at that point. The hold-short lights illuminate the hold-short line, giving you a visible cue in darkness to stop at the correct location. In addition, vertical guidance—such as a precision approach path—provides a defined glide path and altitude information, helping you maintain the proper descent and know exactly when to stop at the hold-short point. Without these elements, nighttime LAHSO would be too risky. PAPI lights don’t mark the hold-short point, and lighting conditions like a full moon don’t establish the required instrumentation and cues. Likewise, having no electronic guidance would remove the necessary vertical guidance. Hence, the required condition is hold-short lights and vertical guidance.
