Which system is intended to provide a means to transition from instrument to visual flight for landing?

• A. Visual Approach Slope Indicator (VASI)
• B. Chart
• C. Legend
• D. Approach Lighting System (ALS)

Answer: (D)

The idea here is that preparing to switch from relying on instruments to seeing the runway is aided by lighting that highlights the approach path and runway environment. An Approach Lighting System is designed to illuminate the approach and runway area, giving you clear visual cues as you near the airport so you can transition from instrument flight to visual flight for landing. It helps pilots acquire the runway visually in low visibility or at night, bridging the gap between IFR procedures and a visual touchdown. Visual indicators like a Visual Approach Slope Indicator provide guidance on whether you’re on the proper descent path once you already have the runway in sight, but they don’t supply the broader runway environment cues that begin the transition. Charts and legends are navigational aids, not lighting systems that assist with the actual transition to visual landings.
