ATC ATC Radar and Technology 3

Question 1

What is EDST (En Route Decision Support Tool) used for in ARTCC operations?

Accepted Answer

To assist controllers with conflict detection and trial planning in en route airspace

Answer

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.

Question 2

What is a 'handoff' in radar ATC operations?

Accepted Answer

The electronic transfer of radar track control from one sector to another

Answer

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.

Question 3

What does ADS-B stand for and how does it differ from traditional radar?

Accepted Answer

Automatic Dependent Surveillance-Broadcast; aircraft broadcast their GPS position rather than being detected by ground radar

Answer

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.

Question 4

What is the purpose of a 'data block' on a radar display?

Accepted Answer

To display aircraft callsign, altitude, and speed next to a radar target

Answer

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.

Question 5

What does 'radar vectoring' refer to in ATC operations?

Accepted Answer

Providing specific magnetic headings to navigate an aircraft to a desired point

Answer

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.
