  1. What is the definition of 'conflict alert' in ATC radar systems?

    Answer: An automated warning that two aircraft are predicted to violate separation minima

    Conflict alert is an automated radar function that warns controllers when two tracked aircraft are predicted to lose required separation.

  2. During a ground stop, which aircraft are typically exempt from holding?

    Answer: Aircraft that declared a fuel emergency

    Aircraft declaring a fuel emergency are prioritized for landing regardless of ground stop or flow programs.

  3. What is the purpose of a LAHSO (Land and Hold Short Operations) clearance?

    Answer: To authorize simultaneous use of intersecting runways while maintaining separation

    LAHSO allows controllers to land aircraft on intersecting runways simultaneously by requiring aircraft to hold short of the intersection.

  4. A controller notices two aircraft on radar are converging at the same altitude. The first action should be to:

    Answer: Issue an immediate altitude change or turn to one or both aircraft to resolve the conflict

    The controller's first priority is to issue an immediate clearance to resolve the conflict and restore separation.

  5. What does 'IMC' stand for and how does it affect ATC responsibilities?

    Answer: Instrument Meteorological Conditions; ATC is responsible for all separation

    IMC means Instrument Meteorological Conditions, where visibility is too low for visual flight and ATC must provide all IFR separation.

  6. An aircraft on an IFR flight plan in controlled airspace requests a visual approach. What is required?

    Answer: The airport must be VFR and the pilot must have the airport or preceding traffic in sight

    A visual approach requires the airport to be VFR and the pilot to have either the airport or preceding traffic in sight.

  7. What is a 'handoff' in ATC operations?

    Answer: The transfer of radar identification and communications responsibility from one controller to another

    A handoff transfers radar identification and communication responsibility for an aircraft from one controller position to another.
