Which elements are required inside the AC symbol?

The correct answer outlines the key elements that must be included in the Airspace Control (AC) symbol. This symbol is essential for effective communication and coordination in air operations, particularly for defining the parameters of airspace and ensuring the safe and efficient use of that space.

Including "Name" is fundamental as it identifies the specific airspace or operation in question, which is crucial for clarity. The "Width" is necessary to define the lateral boundaries of the airspace, ensuring that all users are aware of the extent of the area in question. The "Min ALT" and "Max ALT" are critical as they specify the vertical limits of the airspace, which helps in managing altitude conflicts and ensuring safe operation below or above the defined airspace.

Together, these elements create a comprehensive framework for air operations, making it possible for various units to coordinate effectively and operate within the defined parameters, thus enhancing safety and mission effectiveness.
