"Meatball"

Tagged:  

Meatball — This series of lights aids the pilot in lining up for the landing. In the center are amber and red lights with Fresnel lenses. Although the lights are always on, the Fresnel lens only makes one light at a time seem to glow, as the angle at which the pilot looks at the lights changes. If the lights appear above the green horizontal bar, the pilot is too high. If it is below, the pilot is too low, and if the lights are red, the pilot is very low. If the red lights on either side of the amber vertical bar are flashing, it is a wave off.
