e. Pilot Actions: 1.When operating at airports with RWSL, pilots will operate with the transponder “On” when departing the gate or parking area until it is shutdown upon arrival at the gate or parking area. This ensures interaction with the FAA surveillance systems which provide information to the RWSL system. 2.Pilots must always inform the ATCT when they have either stopped, are verifying a landing clearance, or are executing a missed approach due to RWSL or FAROS indication that are in conflict with ATC instructions. Pilots must request clarification of the taxi, takeoff, or landing clearance. 2.1.8 Airport Lighting Aids 3.Never cross over illuminated red lights. Under normal circumstances, RWSL will confirm the pilot’s taxi or takeoff clearance. If RWSL indicates that it is unsafe to takeoff from or taxi across a runway, immediately notify ATC of the conflict and confirm your clearance. Never land if PAPI continues to flash or pulse. Execute a go around and notify ATC. 4.Do not proceed when lights have extin-guished without an ATC clearance. RWSL verifies an ATC clearance, it does not substitute for an ATC clearance. f. ATC Control of RWSL System: 1.Controllers can set in.pavement lights to one of five (5) brightness levels to assure maximum conspicuity under all visibility and lighting condi-tions. REL and THL subsystems may be independently set. 2.The system can be shutdown should RWSL operations impact the efficient movement of air traffic or contribute, in the opinion of the ATC Supervisor, to unsafe operations. REL, THL, and FAROS subsystems may be shutdown separately. Shutdown of the FAROS subsystem will not extinguish PAPI lights or impact its glide path function. Whenever the system or a component is shutdown, a NOTAM must be issued, and the Automatic Terminal Information System (ATIS) must be updated. 2.1.7. Control of Lighting Systems a.Operation of approach light systems and runway lighting is controlled by the control tower (ATCT). At some locations the FSS may control the lights where there is no control tower in operation. b.Pilots may request that lights be turned on or off. Runway edge lights, in-pavement lights and approach lights also have intensity controls which may be varied to meet the pilots request. Sequenced flashing lights (SFL) may be turned on and off. Some sequenced flashing light systems also have intens-ity control. 2.1.8. Pilot Control of Airport Lighting Radio control of lighting is available at selected airports to provide airborne control of lights by keying the aircraft’s microphone. Control of lighting systems is often available at locations without specified hours for lighting and where there is no control tower or FSS or when the tower or FSS is closed (locations with a part-time tower or FSS) or specified hours. All lighting systems which are radio controlled at an airport, whether on a single runway or multiple runways, operate on the same radio frequency. (See TBL 2.1.1 and TBL 2.1.2.)

On runways with both approach lighting and runway lighting (runway edge lights, taxiway lights, etc.) systems, the approach lighting system takes precedence for air-to-ground radio control over the runway lighting system which is set at a predetermined intensity step, based on expected visibility conditions. Runways without approach lighting may provide radio controlled intensity adjustments of runway edge lights. Other lighting systems, including VASI, REIL, and taxiway lights may be either controlled with the runway edge lights or controlled independently of the runway edge lights. b.The control system consists of a 3.step control responsive to 7, 5, and/or 3 microphone clicks. This 3.step control will turn on lighting facilities capable of either 3.step, 2.step or 1.step operation. The 3.step and 2.step lighting facilities can be altered in intensity, while the 1.step cannot. All lighting is illuminated for a period of 15 minutes from the most recent time of activation and may not be extinguished prior to end of the 15 minute period (except for 1.step and 2.step REILs which may be turned off when desired by keying the mike 5 or 3 times respectively). |
