An aircraft is landing on a runway with a displaced threshold. What action should be taken?

• A. Touch down before the threshold
• B. Touch down after the threshold
• C. Maintain speed above stall
• D. Make a go-around

Answer: (A)

When an aircraft is landing on a runway with a displaced threshold, it is important for the pilot to ensure that the landing occurs at an appropriate distance relative to the threshold markings. Touching down before the threshold is the correct action because the displaced threshold indicates that the portion of the runway before that point is not available for landing due to obstructions or safety reasons. By landing before the threshold, the pilot ensures that the aircraft lands on a part of the runway that is safe and authorized for use. The displaced threshold serves as a visual cue to pilots, indicating where the usable runway begins for landing. Landing beyond this point could lead to potential hazards or runway incursions, especially if the space before the threshold is obstructed. Additionally, touching down before the threshold helps ensure there is adequate runway length available for a safe landing, especially crucial for heavy aircraft or in high-density altitude conditions. Maintaining speed above stall is essential in general for any landing, but it doesn't directly address the specific landing protocol required by the displaced threshold scenario. Making a go-around is also a valid maneuver if conditions deem the landing unsafe, but in this case, the correct procedure prescribes a specific touch down point that avoids the hazards of a displaced threshold.
