Runway Status Lights (RWSL) are an automated safety system designed primarily to:
Answer: Alert pilots and drivers of unsafe runway entry conditions without ATC involvement
RWSL automatically illuminates red lights to warn of unsafe runway conditions, supplementing ATC clearances.
What color are in-pavement runway centerline lights in the last 3,000 feet of runway remaining?
Answer: Alternating red and white
Centerline lights transition from all-white to alternating red-and-white in the last 3,000 feet to warn of limited runway remaining.
During a runway visual range (RVR) reading of 600 feet, which lighting system intensity setting would ATC most likely select?
Answer: Step 5 (highest)
In very low visibility such as 600 RVR, maximum intensity (Step 5) is used to maximize pilot visibility of airfield lights.
What is the correct procedure when an airfield lighting outage affects an instrument runway during IFR conditions?
Answer: Issue a NOTAM, notify ATC, and restrict or close the runway as appropriate
An instrument runway lighting failure requires immediate NOTAM issuance, ATC notification, and possible closure to protect IFR operations.
Obstruction lights on structures near the airport must meet which color and flash requirements per FAA regulations?
Answer: Red (steady or flashing) or white strobe, as specified by FAA
FAA specifies red steady/flashing or high-intensity white strobes for obstruction lighting based on structure height and location.
What is the purpose of Stop Bar Lights at runway entrances in low-visibility operations?
Answer: Provide in-pavement red lights requiring vehicles and aircraft to stop until cleared
Stop bar lights are red in-pavement lights at runway entrances activated during low-visibility to prevent unauthorized runway entry.
When performing maintenance on an energized airfield lighting series circuit, technicians must follow which safety protocol?
Answer: Standard OSHA lockout/tagout and FAA-required electrical safety procedures
Lockout/tagout combined with FAA safety procedures is mandatory when working on airfield lighting circuits to prevent electrocution.
