Definition
A cross-reference entry in the Aeronautical Information Manual glossary directing the reader to the main 'Radar' entry for the full definition. The parenthetical 'See Radar' indicates this is a pointer, not a standalone definition, and the reader should navigate to the primary 'Radar' entry to find the meaning.
Plain English
This is a 'look here instead' note in the glossary. It tells you the real definition of Radar is found at another entry — go there to read it.
Context Anchor
Pilots encounter radar in air traffic control services, weather displays, traffic advisories, and discussions of whether an aircraft is visible to a controller.
Derivation
Radar began as an acronym for “radio detection and ranging.” That origin helps because the core idea is exactly that: using radio waves to detect something and measure its distance.
Why Pilots Care
Radar gives pilots and controllers real-time information about nearby traffic and weather, directly supporting separation, avoidance, and route decisions.
Analogy
Radar is like calling out in a dark room and listening for the echo, except it uses radio waves instead of sound. The return tells the system that something is there and helps estimate where it is.
Intuition Check
Radar does not “see” like a human eye or camera. It detects returned radio signals and turns them into useful position or weather information.
Example Sentence 1
Looking up the term in the glossary, the pilot saw 'Radar (See Radar)' and turned to the main Radar entry for the full definition.
Example Sentence 2
The pilot monitored the weather radar for returns along the arrival route.
