# 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.&#x20;
