What should be done with "FUEL" or "NORDO" in radar operations?

In radar operations, important notifications such as "FUEL" or "NORDO" should be recorded in remarks and communicated verbally. This ensures that all relevant parties are aware of the aircraft's condition, which is critical for safety and operational efficiency.

Recording this information in the remarks helps maintain a comprehensive record of the situation, making it easier for air traffic controllers and other personnel to review and respond to the needs of the aircraft. Additionally, verbal communication reinforces the message and ensures that it is not overlooked, promoting better situational awareness among team members. This dual approach of documentation and vocal coordination enhances the safety and effectiveness of radar operations and ensures that all needed actions can be taken promptly and correctly.

The other options would fall short in ensuring full awareness and adequate response to such critical situations, potentially compromising safety.
