During a point out, which phrase indicates that the traffic restrictions have been understood and will be followed?

The phrase that indicates the traffic restrictions have been understood and will be followed is "Traffic acknowledged." This phrase is used in air traffic control communications to confirm receipt of the information regarding the traffic situation. When a controller indicates traffic to a pilot and the pilot responds with "Traffic acknowledged," it shows that the pilot has understood the traffic information and is fully aware of the applicable restrictions or actions required in response to that traffic. This creates clear and effective communication between the controller and the pilot, enhancing safety and situational awareness in the airspace.

In contrast, "Traffic observed" does not explicitly convey acknowledgment of restrictions or actions yet. "Restrictions noted" implies that the pilot is aware of restrictions, but it does not fully confirm that they will follow them. "Compliance confirmed" suggests that the pilot agrees to comply but is not standard phrasing for communicating acknowledgment of traffic information in real-time interactions.
