airport operationsFAA-published sample question (ATM, Aug 2021)
A Runway Status Light (RWSL) System at an airport
A
relies on ASDE-X/Airport Surface Surveillance Capability (ASSC).✓ Correct Answer
B
allows ATC to override any RWSL false indications.
C
does not require pilots to tell ATC when executing a go-around.
Explanation
AIM 2-1-6 explains that RWSL is a fully automated system driven by surface and terminal surveillance (ASDE-X or ASSC) that illuminates runway entrance and takeoff hold lights. It is independent of ATC input, and pilots must still follow ATC instructions and report go-arounds as usual.
