A PLASI system usually has an effective visual range of 5 nm during the day and up to 20 nm at night. When on the correct vertical profile, a steady white light will be seen, if above it, the white light will flash and if below it, a steady red light will show.

The PLASI, Pulse Light Approach Slope Indicator, is a ground-installed, self-contained device, which visually provides vertical glide path information including correct position and direction, as well as degree of deviation and rate of change of deviation from the correct glide path.
