When does the phraseology require that good judgment must be exercised?

The phraseology that requires good judgment to be exercised is typically associated with non-standard situations. This is because non-standard phraseology often refers to scenarios that are not covered by established protocols or guidelines, necessitating a more flexible and situational understanding of the circumstances at hand. In these cases, air traffic controllers must assess the unique aspects of the situation, such as weather conditions, traffic density, or the behavior of an aircraft, and make decisions based on their training, experience, and the specific details of the situation.

In contrast, standard phraseology refers to well-defined procedures that are universally understood, which do not require subjective judgment, while emergency situations may have established commands that guide actions. Controlled circumstances typically imply a clear structure where actions are less variable and more consistent, thus not requiring the exercise of personal judgment. In non-standard cases, the need for discretion and adaptability is paramount, highlighting the importance of good judgment.
