Which term describes the signal a transponder sends back to the radar?

• A. Transmitted signal
• B. Responses
• C. Squawk code
• D. Interrogation

Answer: (B)

The term describing the signal a transponder sends back to the radar is "Responses." When a transponder receives an interrogation signal from ground radar, it responds with specific information about the aircraft, including its identity and altitude. This response is crucial for air traffic control (ATC) as it aids in the identification and tracking of the aircraft on a radar display. The transponder itself is a critical component of radar systems used in aviation. Its responses enhance situational awareness for both ATC and pilots by providing vital data regarding the aircraft’s status and movements. This information helps in managing airspace safely and efficiently. The other terms may relate to aspects of radar or transponder operations, but they do not accurately describe the signal that the transponder actively sends back. "Transmitted signal" is a broader term and does not specifically identify the nature of the signal from the transponder. "Squawk code" refers to the specific code set by the pilot or automatically assigned to the transponder, which is communicated during the response but does not capture the essence of the signal itself. "Interrogation" pertains to the initial signal sent by radar to the transponder, rather than the response signal that is sent back. Thus, "Responses" is the
