What is the wheel height limit for aircraft using a 3 bar VASI?

• A. Less than 10 meters
• B. Up to 14 meters
• C. Up to 10 meters
• D. More than 14 meters

Answer: (B)

The correct choice is based on the operational parameters established for the Visual Approach Slope Indicator (VASI) system, specifically the three-bar configuration. A 3-bar VASI is designed to assist pilots in maintaining the correct glide path during an approach to landing, and its functions are particularly suited for aircraft operating at certain heights. The height limit for aircraft utilizing a 3-bar VASI is established at a maximum of up to 14 meters. This ceiling provides a guideline ensuring that aircraft within this range can effectively perceive and follow the visual indicators, which are calibrated for optimal performance within that height threshold. Aircraft above the 14 meters mark may face challenges in receiving accurate visual guidance from the 3-bar VASI, as the system may not be designed to accommodate larger aircraft effectively. This limitation is important for maintaining safety and situational awareness during the landing phase, making the defined height limit critical for operational integrity. Given this context, the height limit of up to 14 meters ensures that the glide path information provided by the VASI remains reliable for pilots as they approach and land.
