Air traffic control signal light gun in use at base flight tower. In the case of a radio failure or aircraft not equipped with a radio, or in the case of a deaf pilot, air traffic control may use a signal lamp (called a "signal light gun" or "light gun" by the FAA [1] [2]) to direct the aircraft.
OCAS uses a low power ground-based radar to provide detection and tracking of an aircraft's proximity to an obstacle such as high buildings, power line crossings, telecom towers or wind turbines. This capability allows the visual warning lights to remain passive until an aircraft is detected and known to be tracking on an unsafe heading.
Air traffic obstacles have to be marked in most cases with red and white colored markings and with aircraft warning lights at night. On larger structures blinking lights are required. An example of an air traffic obstacle is the air traffic control tower. In the past lamps similar to those used on lighthouses were sometimes used.
Lighting on a Houston radio tower reportedly failed just days before it was hit by a helicopter on Sunday, killing four people in a fiery explosion that toppled the tower and left debris scattered ...
When you have a number of aircraft obstruction warning lights near each other (for example, several antennas, the two towers typical of suspension bridges, or a row of lights on a tall antenna tower) the lights must flash together.
An annunciator panel, also known in some aircraft as the Centralized Warning Panel (CWP) or Caution Advisory Panel (CAP), is a group of lights used as a central indicator of status of equipment or systems in an aircraft, industrial process, building or other installation. Usually, the annunciator panel includes a main warning lamp or audible ...
