Staying Out of Danger
Consider a scenario in which an airplane is flying at low altitude, potentially near canyons,
lakes, rivers, or airports. In such cases, the aircraft may collide with power lines that are not
immediately apparent. To prevent this, the Federal Aviation Administration (FAA) requires the placement
of these aerial marker balls on power lines that traverse regions with low-flying aircraft activity. By installing these indicators, we make the area safer for both aviators and individuals on the ground.
Colors that catch the eye
Have you ever wondered why marker balls come in a variety of colors? The solution rests on increasing visibility. The colors used—often orange, white, and yellow—are carefully chosen to contrast with varied settings. When flying across the sky, pilots want markers that are impossible to overlook. These bold colors ensure that the markings stand out and warn them to the existence of electrical wires.
