What is EDST (En Route Decision Support Tool) used for in ARTCC operations?
Answer: To assist controllers with conflict detection and trial planning in en route airspace
EDST is a decision support tool used at Air Route Traffic Control Centers (ARTCCs) that helps controllers detect conflicts and evaluate trial plans before issuing clearances to aircraft.
What is a 'handoff' in radar ATC operations?
Answer: The electronic transfer of radar track control from one sector to another
A handoff is the process of transferring radar identification and communications responsibility for an aircraft from one ATC sector or facility to the next as the aircraft progresses along its route.
What does ADS-B stand for and how does it differ from traditional radar?
Answer: Automatic Dependent Surveillance-Broadcast; aircraft broadcast their GPS position rather than being detected by ground radar
ADS-B (Automatic Dependent Surveillance-Broadcast) uses GPS to determine aircraft position, which the aircraft then broadcasts to ground stations and other aircraft, providing more precise tracking than traditional radar.
What is the purpose of a 'data block' on a radar display?
Answer: To display aircraft callsign, altitude, and speed next to a radar target
A data block (also called a 'tag') is the alphanumeric information displayed adjacent to a radar target showing the aircraft's callsign, altitude, and groundspeed to help controllers identify and monitor the flight.
What does 'radar vectoring' refer to in ATC operations?
Answer: Providing specific magnetic headings to navigate an aircraft to a desired point
Radar vectoring involves issuing specific compass headings to guide an aircraft to a particular point, such as an approach course, traffic pattern, or around weather, using the controller's radar picture.
What is a 'point out' in ATC radar operations?
Answer: A procedure where one controller notifies an adjacent controller of an aircraft entering or transiting their airspace
A point out is a coordination procedure where a controller notifies an adjacent sector that an aircraft will enter or transit their airspace, allowing the receiving controller to maintain awareness without assuming control.
