  2. Runway status lights - Wikipedia

    en.wikipedia.org/wiki/Runway_status_lights

    With few exceptions (like an aircraft occupying a runway under a "line up and wait" clearance), an active runway is typically used by only one entity at a time. When an unauthorized person or vehicle enters a runway, whether intentional or accidental, the conflict is known as a runway incursion . [ 3 ]

  3. Automatic Ground Collision Avoidance System - Wikipedia

    en.wikipedia.org/wiki/Automatic_Ground_Collision...

    The Automatic Ground Collision Avoidance System (Auto-GCAS) enhances safety by mitigating controlled flight into terrain (CFIT) accidents. [1] The Auto-GCAS team was awarded the 2018 Collier Trophy for the design-integration and flight testing in the F-35 , marking the year's greatest achievement in aeronautics. [ 2 ]

  4. ACARS - Wikipedia

    en.wikipedia.org/wiki/ACARS

    In aviation, ACARS (/ ˈ eɪ k ɑːr z /; an acronym for Aircraft Communications Addressing and Reporting System) is a digital datalink system for transmission of short messages between aircraft and ground stations via airband radio or satellite. The protocol was designed by ARINC and deployed in 1978, [1] using the Telex format.

    The ground controller frequency is open and is manned whilst the IFR clearance delivery frequency is closed and unmanned - clearance requests should be made to the ground controller. Transition level - flight level 65. Aircraft above Flight Level 65 (6500ft) should set their altimeters to QNH 1013.

  6. Autoland - Wikipedia

    en.wikipedia.org/wiki/Autoland

    Autoland systems were designed to make landing possible in visibility too poor to permit any form of visual landing, although they can be used at any level of visibility. . They are usually used when visibility is less than 600 meters runway visual range and/or in adverse weather conditions, although limitations do apply for most aircraft—for example, for a Boeing 747-400 the limitations are ...

  7. Flight service station - Wikipedia

    en.wikipedia.org/wiki/Flight_service_station

    The Lone Rock Flight Service Station from 1928 to 1985, in the EAA Aviation Museum. A flight service station (FSS) [1] is an air traffic facility that provides information and services to aircraft pilots before, during, and after flights, but unlike air traffic control (ATC), is not responsible for giving instructions or clearances or providing separation.

  8. Standard Terminal Automation Replacement System - Wikipedia

    en.wikipedia.org/wiki/Standard_Terminal...

    STARS replaced the Automated Radar Terminal System (ARTS) at FAA air traffic control facilities across the US, as well as the previous automation systems employed by the DoD. The STARS system receives and processes target reports, weather, and other non-target messages from both terminal and en route digital sensors.

  9. Traffic collision avoidance system - Wikipedia

    en.wikipedia.org/wiki/Traffic_collision...

    A traffic alert and collision avoidance system (TCAS, pronounced / ˈ t iː k æ s / TEE-kas), also known as an Airborne Collision Avoidance System (ACAS), [1] is an aircraft collision avoidance system designed to reduce the incidence of mid-air collision (MAC) between aircraft.
