Definition
A radar simulation system used by air traffic controllers for training. It produces realistic synthetic aircraft targets on a radar display, allowing controllers to practice handling traffic scenarios without using live aircraft.
Plain English
A training tool that puts fake aircraft on a controller's radar screen so they can practice managing traffic safely on the ground before doing it for real.
Context Anchor
Seen in FAA acronym lists and in discussions of air traffic control surveillance and display systems; pilots normally encounter it in documents rather than as a cockpit control.
Derivation
‘Enhanced’ means improved over earlier versions; ‘target’ is the radar term for an object showing up on the scope (such as an aircraft); ‘generator’ means it produces or creates those targets. Together: a system that creates improved simulated radar returns for training.
Why Pilots Care
Pilots rarely interact with an ETG directly, but knowing the term helps when reading FAA material about how controllers are trained, which affects the quality and consistency of the ATC service pilots receive.
Intuition Check
“Target” here does not mean something to shoot at or aim for. It means an aircraft position shown on an air traffic control display.
Example Sentence 1
New air traffic controllers practice on the ETG before working live traffic, so they can build their skills in a safe environment.
Example Sentence 2
Instructors used the ETG to simulate heavy traffic patterns during controller qualification sessions.
