NOTE
AFLCS is being incorporated into the Video Information
Distribution System (VIDS). VIDS will be discussed later in
this chapter.
AFLCS Description
AFLCS interfaces with electrical switchgear at various locations on an airfield to provide
ON or OFF and intensity control functions for airfield lighting systems. AFLCS consists
of two major groups:
Tower control equipment (TCE) Located in the control tower and displays the
status of the airfield lighting systems on a color monitor. The TCE also responds
to operator control inputs by sending coded commands to various remote control
equipment (RCE) distributed around the airfield.
Remote control equipment (RCE) Responds to commands from the TCE by
changing the status of certain airfield lighting circuits and reporting the new
status back to the TCE for display.
AFLCS Modes of Operation
The AFLCS has two operating modes:
Tower control mode In this position, the operator can directly control airfield
lighting from the tower cab
Local control mode In this position, the tower/local toggle switch disables tower
control of the switches for maintenance purposes.
The control mode is determined by the position of a tower/local toggle switch located on
each vault control unit. The AFLCS is normally operated in the tower control mode.
