When requested to "squawk ident," what is a pilot expected to do?

When a pilot is requested to "squawk ident," the expected action is to transmit the identification code from the transponder. This request is typically made by Air Traffic Control (ATC) to help them identify the aircraft on radar. By activating the "ident" feature of the transponder, it will cause the aircraft's radar return to become more prominent, allowing ATC to recognize the specific flight more easily.

The transponder serves as a crucial tool in air traffic management, providing information such as the aircraft's altitude and identity. When the pilot responds to the request, they enhance situational awareness for both themselves and ATC, facilitating safer and more efficient air traffic control. This procedure is particularly important in busy airspace, ensuring that all aircraft are accounted for and correctly identified.

Other options, such as turning off the transponder, would inhibit the aircraft's visibility on radar, counteracting the purpose of the request. Increasing altitude or changing the flight plan does not relate to the specific action requested, which is solely about identifying the aircraft. Overall, squawking ident is a straightforward yet significant procedure to maintain clear communication and navigation within the controlled airspace.
