    en.wikipedia.org/wiki/Aviation_light_signals

    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.

    en.wikipedia.org/wiki/Air_traffic_control_radar...

    The antenna system of a typical air traffic control radar, the ASR-9. The curved reflector antenna on the bottom is the primary surveillance radar (PSR), and the flat antenna on top of it is the secondary surveillance radar (SSR). In operation the antenna rotates about a vertical axis, sweeping a vertical fan-shaped beam of microwaves around ...

  7. Optical communication - Wikipedia

    en.wikipedia.org/wiki/Optical_communication

    An air traffic controller holding a signal light gun that can be used to direct aircraft experiencing a radio failure (2007). Signal lamps (such as Aldis lamps), are visual signaling devices for optical communication (typically using Morse code). Modern signal lamps are a focused lamp which can produce a pulse of light.

  8. Marker beacon - Wikipedia

    en.wikipedia.org/wiki/Marker_beacon

    It is typically located about 1 NM (1.85 km) inside the point where the glideslope intercepts the intermediate altitude and transmits a 400 Hz tone signal on a low-powered (3 watts), 75 MHz carrier signal. Its antenna is highly directional, and is pointed straight up. The valid signal area is a 2,400 ft (730 m) × 4,200 ft (1,280 m) ellipse (as ...

  9. Airfield traffic pattern - Wikipedia

    en.wikipedia.org/wiki/Airfield_traffic_pattern

    By using a consistent flight pattern, pilots will know from where to expect other air traffic and be able to see and avoid it. Pilots flying under visual flight rules (VFR) may not be separated by air traffic control, so this consistent predictable pattern is a vital way to keep things orderly. At tower-controlled airports, air traffic control ...
