Long Range Lineup System (LRLS)
Uses color-coded lasers to provide horizontal lineup information of approaching aircraft. The color and flashing rate of the laser indicate the angle with respect of the centreline.
Steady amber indicates aligned with the centerline
An increasing rate of flashing indicates that the aircraft is deviating away from the centerline.
Green indicates an angle of deviation towards the Starboard side
Red indicates an angle of deviation towards the Port side
