Line 5:
A normal glidepath is indicated by an even split in red and white lights. If an airplane is beneath the glidepath, more red lights are visible to the pilots; if an airplane is above the glidepath, more white lights are visible.
 
During aircraft [[descent]], this system, along with other airport lights, may be activated by the [[aviator|pilot]] by keying the airplane [[microphone]] with the airplane's communication radio tuned to the [[CTAF]].
