is impractical for safety reasons, the crew should
proceed according to their best judgment while
understanding the illuminated lights indicate that
continuing the takeoff is unsafe. Contact ATC at the
earliest possible opportunity.

Pilot Actions:
1.
When operating at airports with RWSL, pilots
will operate with the transponder/ADS
−
B “On” when
departing the gate or parking area until it is shut down
upon arrival at the gate or parking area. This ensures
interaction with the FAA surveillance systems such
as ASDE-X/Airport Surface Surveillance Capability
(ASSC) which provide information to the RWSL
system.
2.
Pilots must always inform the ATCT when
they have stopped due to an RWSL indication that is
in conflict with ATC instructions. Pilots must request
clarification of the taxi or takeoff clearance.
3.
Never cross over illuminated red lights.
Under normal circumstances, RWSL will confirm the
pilot’s taxi or takeoff clearance previously issued by
ATC. If RWSL indicates that it is unsafe to takeoff
from, land on, cross, or enter a runway, immediately
notify ATC of the conflict and re-confirm the
clearance.
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.
5.
Never land if PAPI continues to flash.
Execute a go around and notify ATC.
e.
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.
System lights can be disabled should RWSL
operations impact the efficient movement of air
traffic or contribute, in the opinion of the assigned
ATC Manager, to unsafe operations. REL and THL
light fixtures may be disabled separately. Whenever
the system or a component is disabled, a NOTAM
must be issued, and the Automatic Terminal
Information System (ATIS) must be updated.

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 intensity
control.

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
