ALSs provide what type of information?

• A. the basic means to transition from instrument flight to visual flight for landing
• B. visual descent guidance information during approach to a runway
• C. visual indication that all traffic is clear of the runway
• D. the basic means to communicate with air traffic control

Answer: (A)

Approach Lighting System provides a visual path and cues that help a pilot switch from instrument flight to visual flight for landing. It guides the pilot toward the runway and helps establish the runway environment as the aircraft nears the threshold, aiding distance and alignment perception as you transition to visual contact. It does not supply vertical descent guidance like an ILS, nor does it indicate when all traffic is clear of the runway, nor handle radio communication with ATC.
