With AFL (Airfield Lighting) from Siemens combined with ALCS (Airfield
Lighting Control System) and dedicated sensors installed on the airfield,
Siemens provides highly efficient and effective solutions for control and
monitoring of visual aids and ground traffic movements.
Through AFL, intelligence is distributed over the airside area, allowing control
and monitoring of individual lights. Decentral sensors detect movements of
aircraft and other vehicles on the ground. The signals from individual lights
and sensors are communicated via AFL and are comprehensively visualized for the
operators in the tower through an ALCS.
AFL enables the controllers to optimize the use of the entire airfield lighting
system: through flexible control of each segment of the runway, taxiway and
apron circuits, every component and individual lamp is exactly controllable. As
such, AFL provides excellent tools to perform control of aircraft ground
movements: taxiway routing, stopbar control, runway incursion detection are now
available for the operators in the tower. Safety of air traffic movements and
number of slots per day are significantly increased with this modern and
reliable control system.
Using
the power supply series circuit for reliable and high-speed communication
between substation and individual lamps, AFL detects and supervises the actual
status of each lamp and provides complete detailed information to the
operational control station. AFL continuously monitors all lamps controlled via
the system and identifies a lamp failure immediately, indicating the exact
position of the failed lamp. As a result, the need for regular visual
inspections is reduced and overall maintenance performance can be improved.
