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
