Which of the following is NOT an approved Field F entry without verbal coordination?

The option indicating "Traffic updates" is indeed classified as not an approved Field F entry without verbal coordination. In air traffic control, certain entries can automatically be processed in field F, while others require verbal coordination to ensure safety and clarity in communication.

Traffic updates involve dynamic changes that can significantly affect the aircraft's position and safety, requiring real-time assessment and communication between controllers and pilots. These updates may need immediate contextual awareness of both the traffic situation and the aircraft's intended actions, which is not guaranteed through automated entries.

In contrast, assigned speeds, headings, and weather deviations are relatively standardized inputs that can be communicated clearly through data entries in field F, as they are typically predetermined and do not require real-time dialogue to verify or clarify actions. This allows air traffic controllers to manage traffic more efficiently without the need for additional verbal coordination in these situations.
